Your car may have a transmission fluid leak for a variety of reasons, but before we talk about why you have a transmission fluid leak, it’s important to talk about how to identify one. You’ll notice a bad transmission fluid leak when parked when you see some funny color or funny smelling oil on the garage floor when you move your car. Transmission fluid is often red and has a distinctly unpleasant odor. This doesn’t guarantee a transmission leak, as many power steering systems also use transmission fluid as the working fluid. While you’ll likely notice when transmission fluid is leaking fast, if you’ve got a slow leak, you might be experiencing shifting problems or you might not have any other indication that something is wrong. Since these symptoms can be misleading, it’s important to actually check your transmission fluid level looking for signs of a leak.
On most cars, you can check your transmission fluid level using the dipstick much like checking your engine oil. The dipstick is often a different color or say “trans” on the handle and will be towards the middle or back of your engine bay. You have to check the fluid level when your car is warmed up, after a 20-30 minute drive, and with the engine idling in Park on level ground. If the level is low, the only cause could be a leak. It’s important to stop a leak quickly to keep your transmission fluid at the correct level to prevent damage to your transmission.
Causes of a Transmission Fluid Leak:
- Not changing transmission fluid often enough
- Impact or accident
- Normal wear and tear
Not changing fluid often enough
Since there aren’t a lot of ways for the transmission fluid to leak out, there aren’t many causes of leaks. One of the main culprits is simply not hanging your transmission fluid often enough. Your vehicle’s owner’s manual will give you the recommended service intervals for changing your transmission fluid under normal and extreme driving conditions. If you’re wondering how often you should change your transmission fluid, most vehicle’s owner’s manuals can be found online easily! As you drive, your transmission fluid picks up tiny bits of metal as the components inside wear. If you don’t change your fluid often, these bits of metal add up and can start wearing down the seals and gaskets in your transmission prematurely.
Impact or accident
If one of your wheels or axles is hit during an accident it can cause a transmission fluid leak. Your transmission has between 1 and 3 outputs shafts that are either driveshafts or CV axles leading differentials or out to your wheels. If any of these shafts are pushed into or jarred hard enough they can damage the seals in your transmission causing leaks after the accident. If you suspect this to be the cause of your leak, it’s often best to replace the seals and check the transmission casing for cracks or damage.
Normal Wear and Tear
Normal wear and tear can cause transmission fluids leaks simply due to the operating environment of your transmission. For example, the output shafts all come in direct contact with the seals around them so the motion of the shaft will eventually wear down the seal and cause a leak. Also, the temperature swings and constant shifting of the transmission can cause movement between the seals and gaskets in your transmission eventually leading to leaks as well.
Often times, replacing the leaking gaskets or seals in your transmission can be extremely expensive due to the labor cost associated with the repair. A less expensive way to seal your current leak, or prevent future issues with your car leaking transmission fluid, is to add BlueDevil Transmission Sealer to your transmission. BlueDevil Transmission Sealer is not like other transmission sealers that fill your transmission with powders or a thick sludge, to clog up your leaks, and consequently other parts of your transmission. BlueDevil Transmission Sealer is safe to leave in your transmission fluid until your next fluid change and will not clog or harm your transmission in any way. BlueDevil Transmission Sealer will expand and soften the seals and gaskets in your transmission to restore them to their original condition sealing your leaks permanently.

Very well, you have explained about transmission fluid leak and the ways listed in this article are amazing and easy to use. I have seen many people that haven’t proper knowledge of this transmission fluid leak but your information will properly guide them.
I am not sure if Trans oil e ough or need to ad up before i ad blue devil to stop leak if any….?
Ali-
You want to make sure that you do not overfill the transmission. When adding the product you will want to make sure the transmission has the proper amount of fluid, not too high or too low. You should add 1 ounce of BlueDevil Transmission Sealer to every 1 quart of fluid capacity.
Thank you!

It’s taken me 5 quarts to go40 milesit seems to be leaking outve the front seal out the tranny housing will that blue devil sealer still solve my problem 8f it’s leaking that much???
Chris-
Unfortunately, it seems like you may be losing fluid a little too quickly for the BlueDevil Transmission Sealer to be effective. Typically with the product, you would start to notice improvement after about 100-200 miles of driving. Based on your description, you may lose your full capacity before getting to that 100-200 miles. A hard part repair may be your best option.
Thank you!

My 99 f150 has a transmission leak , I had my transmission rebuilt two weeks ago . and my mechanic won’t pick up the phone . I’m not sure if your product is for me ?
Frank-
If the leak is coming from any of the rubber seals or gaskets in your Transmission then we do recommend using BlueDevil Transmission Sealer. The correct amount to use is 1 ounce of BlueDevil per every 1 quart of capacity. You can expect to start seeing results after about 100 miles of driving.

I have a 2006 impala ss. It has a leak which I add a bottle off transmission fluid every to day. Not to mention rebuilt last year . tried to find the leak but all I saw was transmission fluid. Under but on the car and a little on the ground also on my exhaust could you tell me something about this problem
Robert-
Based on the amount of fluid you are losing we recommend having it taken to a transmission shop or dealership sooner than later. With a leak that large it would not take much for the fluid to become dangerously low which would potentially create the need for a transmission rebuild.
Thank you!
-BDP
I have a 2000 Ford expedition was driving cut it off transmission fluid started leaking out bad
Martha,
The first step will be to determine where the leak is coming from. Since you drive an SUV it should be easy to check under your truck and see if the fluid is leaking from the front, middle or back of your transmission. Depending on the speed of leak, we recommend using BlueDevil Transmission Sealer to stop your leak.

My transmission fluid is leaking from where the dip stick goes , will the blue devil stuff work for me ?
Netta-
The BlueDevil Transmission Sealer would only influence rubber seals/gaskets. If the leak was coming from a plastic or metal component, unfortunately, the product would not be able to seal.
Thank you!

Okay blue devil I read all of about your product.I have a 1996 Ford thunderbird and when I put transmission fueled in it comes right out what do you think the problem might be should I buy blue devil and put it in at the same time or do I need a new gasket or..?
Donsha-
Thank you for asking about your Ford Thunderbird. Based on your description, we do not recommend using BlueDevil in this case. Unfortunately, it seems you are losing fluid too quickly in order to get the benefit of using the product. A hard part repair may be your best option.

What can cause my stern wheel to pull to the left like I have a flat tire and and then I pulled it back in place and something broke or busted and put a hole in my transmission pan?? And I drive a 5 speed Suzuki Forenza 2005…
And also it all happened at once when I was driving on the highway and my car was not making no sound or nothing all at once when my stern wheel pulled to the left I drove it to McDonald’s and then my transmission pan had a hole in it and fluid was leaking out something broke!! Hope you can help me out??
Allen,
Thanks for your question about your Suzuki Forenza. Based on your description of what happen our best guess is that a tie rod or CV joint broke while you were driving. If CV joint broken it would make a lot of noise, so our guess is that you have a broken tie rod or another suspension component. Based on the damage you described you should be able to see what is wrong relatively easily by climbing under your vehicle and inspecting the suspension and drivetrain.
Thanks again for your question!

How do you add to a sealed one?
Cheryle-
Unfortunately, the only way to add fluid to a sealed transmission system would be to drop the pan. With not having a dipstick, it would be tough to tell how much room is in the system when adding the product, and could lead to overfilling issues. A hard part repair may be your best option.
Thank you!

The BlueDevil Transmission Sealer is intended for the rubber seals/gaskets in the system. As long as the leak is coming from one of those rubber seals/gaskets, you should be able to see some great results from the product. Typically, you should expect to see results after about 100-200 miles of driving.

I got a Chevy Malibu 2012 it’s been leaking transmisión oil for a couple of months but I try to add enough to keep it at average level
I can not identify where it is leaking from but it’s rite under the front side of driver side tire. Also I had a small accident on the door but i highly Doubt that could have cause the leak could any body help
Robert,
Thanks for your question about your 2012 Chevy Malibu. Based on your description of the leak location, our guess would be that your transmission is leaking from the output shaft seal or the seal that is around your CV axle on the driver’s side. You may consider replacing that seal or using BlueDevil Transmission Sealer to stop the leak so you don’t have to keep adding fluid.
Thanks again for your question!

the pan has been dented enough to crease a crack wich will leak or bolts need snugginh up tighter otherwise there is a level dcrew to chevk the gluid level on dideof housing if loosened and fluid comes out its over filled let it drain to drip then tighten bolt back in hole thats rite level of gluid could have a crack in aluminum near mount since its bolted to tire axke.
I have a 2005 Chevy blazer I had transmission fluid ,filter and two relays changed in it. Before I did I never lost any training fluid but now it has been done I am losing a quart of fluid about every two days but not seeing anything leaking. But only been driving it again for about a week now. Why am I losing fluid now after serving it. When before I service it never was it low
Misty-
Thank you for asking about your Chevy Blazer. Based on your description, one possibility is that a leak was already present in the system but, was being plugged up by debris/metal shavings and stopping the system from losing fluid. Once the fluid and filter was changed, it may have removed this debris and allowed fluid to leak through. To stop the loss of fluid, we recommend using the BlueDevil Transmission Sealer. You will use one oz. of the product per quart of fluid in the system, and should expect to start seeing results after 100-200 miles of driving.
Thank you!

check the lines that are connected to radiator as they are coolant lines flowing fluid through a seperaye raduator than the 2 youre coolant does
Thank you so much for the info on leading transmissions. It was extremely helpful and I appreciated having the info when I was unable to speak with my mechanic.
I have a 1964 flat head 4 cly Rambler 330.It has transmission fluid that comes up through the dip stick.Can you tell me why this is going on?Thanks a lot.
Tony-
Thanks for your question about your 64 Rambler! Transmission fluid flowing out of the dip stick can only happen if your transmission fluid is over full or if the pressure in your transmission is too high due to a clog or stuck valve. The best place to start would be to change your transmission fluid and filter and then check to make sure the level is correct. If you still have fluid flowing out of your dip stick tube then you probably have a significant clog and may need to rebuild your transmission.
Thank You!
-BDP

Hi there, i have 2009 hyundai verna, it leak a transmission oil from excessive opening beside dip stick which cover by a rubber thing (originally) and that is happening only with air-conditioning run, what could be possible reasons?
Medhat,
Thanks for your question about your Hyundai. When you have the air conditioning on your engine idles at a higher RPM which would raise your transmission pressure and could cause the leak to get worse. Based on your description I don’t think BlueDevil Transmission Sealer will seal your leak. We would recommend purchasing a replacement grommet for your transmission dipstick tube to stop the leak.
Thanks again for your question!

Mario-
Yes, the BlueDevil Transmission Fluid can be used in and is compatible with manual transmissions. You should add 1 ounce of BlueDevil to every 1 quart of fluid capacity (you will not need the full bottle). Expect to notice results after about 100 miles of driving.
Thank You!

I have a 2002 Ford expedition and had it at the shop to see why it acts like it don’t want to take the gas. They had it hooked up to the machine and was giving it some gas no codes came on and they let it run for a might and next thing we know transmission fluid was pouring out. Why would it do that? I wasn’t even there for my transmission.
April-
The problems you are having may be related. If your engine wasn’t giving you any codes but wasn’t working right, it could have been the transmission that was holding your truck back and making it feel like the gas wasn’t working. The fact that it suddenly started leaking transmission fluid is an indication that something relatively serious went wrong in your transmission like a failed bearing or broken gear. Hopefully the shop you were at will be able to help you figure out to repair your transmission.
Thanks!

I have a 2000 Pontiac Bonneville and its leaking fluid bad from the transmission. And it was acting as if it didn’t want to keep driving as the gas pedal went all the way to the floor. And slowed down a little As I was driving but pick back up speed after a couple of seconds. So I parked it I haven’t drove it since. Can you tell me what it could be please.
Kywana-
It may be due to how low your fluid level had gotten. It sounds like the leak you have is beyond what our product, BlueDevil Transmission Sealer, is intended to seal. We recommend having a transmission specialist take a look at it.
Thank You!

Hi,
I have recently purchased a 1994 Holden station wagon VR. There is a transmission leak. That’s all i know.How do i find out where the leak is and what is responsible for it? How much roughly would it cost to get it fixed via a mechanic compared with bluedevil transmission sealer?
Dylan-
It is possible that one of the seals in your transmission system has deteriorated and cracked and thus, a leak has started. The BlueDevil Transmission Sealer, found here http://store.gobdp.com/transmission-sealer-00236/, is intended for leaks in the system that are seeping or dripping. As long as your leak isn’t too large, we would recommend using the BlueDevil Transmission Sealer. Feel free to contact us at 888-863-0426 with any other questions.

Hello i have a 2003 eclipse i was wanting to know if maybe you can tell me what is wrong i recently changed my starter and i ran it about 15 miles and i parked my car overnight and all my transmission fluid was leaked out can you maybe tell me why this happened. Thank you
Heather,
Thanks for your question about your 2003 Eclipse. The only way we could see these two problems being related is that your transmission bolts are slightly loose allowing your transmission to move in relation to the engine. your starter bolts are usually part of what holds the transmission to the engine, so if they were also loose it could allow your transmission to move enough to ruin the input shaft seal or your torque converter. Since you mentioned all the fluid leaked out over night, it sounds like you have a pretty substantial leak and may be better off replacing the seals. It is also possible that your starter replacement and transmission leak are unrelated and just a coincidence.
Thanks again for your question!

I have a 2001 honda accord i went to get a oil change and they told me that my gasest /transmission was leaking,i have not notice any leakage in my driveway or garage,but i have notice a hesitation when taking off,can you. tell why this is happeing
Dreena,
Thanks for your question about your Honda Accord. It is possible that your transmission is leaking only when you’re driving so you don’t notice the drips in one place. We would recommend checking your transmission fluid level using the dipstick while the car is parked and idling. If you find a low fluid level, that would indicate a leak and explain the hesitation. If this is the case we would recommend adding BlueDevil Transmission Sealer (available here: http://store.gobdp.com/transmission-sealer-00236/) to seal the leak and keep your transmission fluid level normal.
Thanks again for your question!

I have a front seal that’s leaking. Will this blue devil stop it from leaking. I had a reconditioned transmission installed 12 months ago. It has 15,000 miles on this transmission right now. Thank you
Holly-
Yes, the BlueDevil Transmission Sealer is specifically designed to stop transmission fluid leaks coming from the seals/gaskets within your transmission. You should add 1 ounce of BlueDevil per every 1 quart of capacity; in many cases you do not need to add the full bottle. Once the product is added you can expect to start seeing results after about 100 miles of driving.

I read the article and I’ve been reading thru the comments and just have a question. I have a 1998 nissan 200sx/se. It just started slowly leaking small drops of what I believe is transmission fluid. It’s coming from the front middle underneath the car. I want to try the Blue devil and see if that helps. My teansmission fluid is at the full mark tho is it still okay to put the Blue devil in? Or will it overfill it?
Kristian-
It is very important not to overfill the transmission system. If you are at capacity, you would want to drain enough fluid out to allow for the recommended amount of the BlueDevil Transmission Sealer. You will be using one ounce of the product per quart of fluid in the system.
Thank you!

I’m not sure as to what to d . Any suggestions??
Carla-
As long as the leak is only seeping or dripping out, you would be able to use the BlueDevil Transmission Sealer. You will use one ounce of the product per quart of fluid in the system. If the leak is a little larger, you may want to bring the vehicle in to a transmission specialist.
Thank you!

Red granny fluid on the engine pan underneath the front suspension. Some harder shifts than usual. Any ideas?
Adam-
A good place to start would be to check your transmission fluid level. Chances are it may be a little low based on the fact that you have seen some transmission fluid leak out. Having the transmission fluid level too high or too low will often cause the transmission to act erratic. We recommend adding the proper amount of the BlueDevil Transmission Sealer to address the leak and then be sure the transmission fluid is filled to the correct level.
Thank you!

I own a 2009 Nissan Rogue. I took it to the dealer and they said I have cracks and that transmission fluid is leaking but I haven’t noticed any on the floor. Should I use the transmission sealer just in case?
Andrea-
The BlueDevil Transmission Sealer is made specifically to rejuvenate & recondition the seals and gaskets within the transmission. If you leak is coming from a crack rather than from around the seals/gaskets then the BlueDevil would not be appropriate to use. You may want to confirm with the mechanic where exactly the leaks are coming from so that you will be able to determine whether or not BlueDevil would be a good option.
Thank you!

I have an 03 suburban with a 4l60e.The torque convertor seal is slightly leaking.It is not dripping off just pooling to a drip.The fluid is topped off and seems to be fine every time i check it.How much would i use of the blue devil.I know 1 ounce per quart but what the total amount and with the fluid topped off will it be ok to still pour in?????
James,
Thanks for your question about your 2003 Suburban. Your transmission holds quite a bit of fluid but the pan only holds about 3 quarts so we would recommend adding BlueDevil Transmission Sealer 3 ounces at a time and continuing to check your fluid level. If the first 3 ounces is enough to seal the leak, you can stop there, but if the leak continues, add 3 ounces again once the fluid level has dropped slightly.
Thanks again for your question!

Trina-
For the oil loss we recommend adding one 8 ounce bottle of the BlueDevil Oil Stop Leak. This will help rejuvenate the seals and gaskets in the system to eliminate any leaks.
For the transmission fluid leak you are experiencing we recommend using the proper amount of BlueDevil Transmission Sealer (1 ounce of BlueDevil treats 1 quart of capacity). With both products you can expect to start seeing results after about 100 miles of driving.

Hello. My daughter is driving a recently purchased used 2005 Mazda 3. After driving it for only 1 week we noticed the transmission fluid is leaking into the engine oil. Any suggestions on why this happened or what to do?
Shelley and Jeff,
Thanks for your question about your daughters 2005 Mazda 3. Thinking through your question, we’re having a very difficult time imagining a scenario where the transmission fluid could get into your engine oil. Your engine should be a sealed system that would be very difficult to get any liquid into. Also, to our knowledge, there isn’t any location on your car where your engine oil and transmission fluid (or any other fluid) come in close proximity. We would recommend changing your engine oil to make sure it is pure as transmission fluid could thin it out your engine oil and start to cause damage.
Thanks again for your question!

Where and why would my transmission pour out all its fluid. It was not pouring out of the dip stick. I parked the car for 10 hours then added fluid and drove the car about five miles and it drove fine and it wasn’t leaking
Cole,
Thanks for your question about your transmission fluid. The most likely places for a leak would be at the axle or driveshaft seals so you can check there for damage or evidence of a leak point. It seems very unusual for a leak that severe to suddenly stop, so the only other thing we would recommend checking is your power steering system. In many cars power steering fluid can look a lot like, or actually be transmission fluid so it is possible that is your leak point.
Thanks again for your question!
-BD Auto Pro
I have a 2003 Pontiac Aztek and I have transmission fluid pouring out of the transmission in the front bottom of my car what can it be?
Jonathan Boyd,
It sounds like you’ve got a pretty major leak based on your description. If the leak is from your transmission, the most likely location would be at one of your axle seals. Look for the CV axles running from you wheels up to the transmission and seeing if you find the leak where the axle enters the transmission. If the leak is as bad as you make it sound, you most likely need to replace the seal. The other possibility is that you actually have a power steering leak. Your power steering system operates at a high pressure so a leak will allow a lot of fluid to run out. Check your power steering fluid reservoir level. If it is extremely low, your leak could be from your high pressure line, or from the rack and pinion. Again, if it is as fast as you describe you’re probably better off replacing the line or seal.
Thanks again for your question!
-BD Auto Pro
can bad cvs cause atf leaks have changed seals on my toyota spacio bt stil leaking
Bonny,
It is possible that a bad CV axle could cause a transmission fluid leak. If the joint is extremely worn it could cause small vibrations which could quickly wear down the shaft seal in your transmission causing a leak.
Thanks again for your question!

2010 Chrysler town and country started smoking. Lifted the hood and pink fluid dripping everywhere..on top of the engine, the battery. No warning lights came on. Had a tire changed the other day, but nothing else…thoughts?
LD,
Thanks for your question about your 2010 Town and Country. It’s difficult to tell what sort of fluid your car is leaking based on your description. it could be pink coolant like DEX-Cool, or it could be transmission fluid or power steering fluid. Our recommendation would be to check all of your fluid levels to try and determine where the leak is coming from. If the smoke you saw looked more like steam, we’d recommend starting with checking your cooling system. If it was heavy or smelled very burnt we would recommend starting with your power steering system.
Thanks again for your question!

Hi I recently purchased a 2009 Ford Escape I noticed the transmission has been leaking I also noticed the dipstick is not attached tight I’ve noticed the leaking starts from the top of the dipstick could it be just the dipstick or something more ?
Daniel-
Thank you for asking about your Ford Escape. The fact that the dipstick was not attached tightly could have allowed fluid to escape more easily. We would recommend tightening the dipstick or replacing it if need be and re-evaluating the situation after that. If you are still noticing a leak after taking this step, you would be a good candidate for the BlueDevil Transmission Sealer.
Thank you!

I have a 2000 Jeep Cherokee 4×4 with 126,000miles. I bought my vehicle back in September and it sat, up until this month. I live in Buffalo,NY, so it sat for the majority of winter. I’ve haven’t even driven it for 2weeks. The previous owner said he replaced the tranny fluid about a year ago. I was driving yesterday and it didn’t seem like my car was having trouble. It felt a tad sluggish maybe. It’s my first vehicle so I’m not accustomed to it yet.
Anyway, last night I was driving and all of a sudden the car wouldn’t accelerate. I was going about 40mph had to break for a brief second so someone could make a turn. When I tried to resume my speed the car wouldn’t accelerate. So I stopped the car and shut it off and restarted it. It drove about 5mph and I was able to get it on a side street before it just completely stopped advancing. I got out pushed it so I wouldn’t be so close to the corner and there was a huge red puddle.
I popped the hood and the very front corner driver side area under the hood was wet. It looked like fluid leaked out on my front driverside tire, and also appeared to leak around the front driver side headlight.
What could be the cause, and how much will it cost me?
Angelica,
Thanks for your question about your 2000 Jeep Cherokee. It sounds like you’ve blown a transmission cooler line on your Jeep. Your jeep has a hose that runs the transmission fluid up to your radiator, then back to the transmission. This system helps keep your transmission fluid cool on long drives or when your towing something. Hopefully, this is simply the case of a broken hose which allowed all your transmission fluid to be pumped out onto the ground and your vehicle to stop driving. If this is the case, the fix is simply a new hose and to refill your transmission with fluid.

My son notice some red fluid on the garage floor my car is not giving me any problems except for it idles high I don’t know where the fluid is coming from do you think it is the transmission it just started leaking but it’s a lot
Win-
The reddish color of the fluid usually indicates transmission fluid. We recommend adding the proper amount of BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/) to your transmission; you should add 1 ounce of BlueDevil per every 1 quart of capacity. Once added, you can expect to start seeing results after about 100 miles of driving.
Thank you!

Is there any sulfur in this product? Will it work in a pre-war brass car with felt seals & Lubritech SP-600 gear oil?
Modern lubricants with Sulfur are very hard on brass parts.
Sir-
Thank you for asking about your 1911 Buick. The BlueDevil Transmission Sealer is only intended for the rubber seals in the system. Unfortunately, it would not have any effect on felt seals. We’re sorry we couldn’t be of more help on this one.

My car, a 2005 Nissan Quest does have transmission oil leakage which I reported to my mechanic. I was told that it was the seal around the converter that was bad; and after it was changed, I discovered that the leakage has not stopped. Could you please advise accordingly? Regards.
Olusegun-
Thank you for asking about your Nissan Quest. As long as you are not losing transission fluid too quickly, you would be a good candidate for the BlueDevil Transmission Sealer. You should expect to see results after about 100-200 miles of driving.

Hi there , I have a 2005 Nissan pathfinder I haven’t had it long but noticed a small oil leak and the garage advised me that it was transition fluid and also my fluid was low so must be that , they said it might cost a few thousand as they will have to disconnect the auto gearbox from the engine and fully diagnose il the leak . It just looks like a small droplet under the trans cover another guy said it didn’t look serious . Should I give your product a go

Will Blue Devil fix the leak in my 2011 Honda Accord transmission leak? My recent visit to STS Tires revealed that my car has such leak. I observed puddles of some funny color or funny smelling oil on the ground where I am parked.
Thanks.

I have a 1999 gmc jimmy. I was driving around a turn and all the sudden my truck stalled. I pulled over with my buddy who was following behind Me. We didn’t think anything of it. We start going again and about 5 feet down the road he is high beeming me. I full over to see smoke poring up from under the passenger side. I look under my car. And tranmition fluid is being dumped onto my muffler causing it to smoke. After it stopped smoking I started her up and checked the transmition fluid. There was some in there but not enough. I know something poped out of place. And I know it’s somewhere on top of the grand cause there is still fluid on my dipstick. (And yes I checked it in gear). Anybody got any answer to what could have happened or what could possible have poped off. Or what hose could be disconnected. And this wasn’t no tipical trans drip is was coming out full force
Jake,
Thanks for your question about your Jimmy. Depending on the motor and transmission you have the leak could be coming from a few different places. With the amount of fluid you saw leaking our recommendation would be to replace or repair the leak as soon as possible. The most likely causes for the leak like you described Would be a break in a transmission cooler line so we would recommend inspecting those first.
Thanks again for your question!

Hi Blue Devil, I have a 98 Ford F150 4X4 Lariat. I was sitting with my Trans in Drive with my foot on the brake stopped for about 30-45mins and all of a sudden I noticed what looked like an ocean of red Trans fluid flowing out from under my truck! I quickly drove to the nearest auto parts store thinking I must’ve blown a Trans cooler line. I also noticed a trail behind me as I drove. When I got to the store & looked to see where the leak was I was surprised to see it wasn’t a cooler line it was coming from the bell housing area where the Engine & Trans meet. So I shut off the truck & let it sit for about 3hrs b4 I tried to start & drive it again. When I finally started it back up & checked for leaks I was shocked to see it was no longer leaking. I filled my trans which was 3qts low & it’s been about 5 days now with no leaks that I’ve noticed. Any ideas as to what happened to cause the leak & how it stopped on it’s own? Thanks so much.
Brandon,
Thanks for your question about your F150. As your transmission heats up the fluid can expand significantly, which is why your transmission dip stick has a “hot” and a “cold” range. It sounds like while you were stopped for so long your transmission got hot enough to push transmission fluid out somewhere as it expanded past where was normal. It could be that pressure got so high it was able to push fluid out past the input shaft seal or it could simply be that fluid was able to escape out of the expansion vent.
We would recommend changing your transmission fluid because if things got that hot, your fluid is probably burnt and new fluid will help your transmission running properly.
Thanks again for your question!

Height of a 2000 Pontiac Grand Voyager that has a terrible transmission leak I can’t figure out where it is and the minute I try to give it gas it pours out as fast as I can put it in when I put it in it’ll drive fine for about 5 minutes and then it won’t go at all and I have to put transmission fluid about every 5 to 10 miles I have to stop and put more fluid in because it’s leaking out that fast where can my leak be
Jill-
Thank you for asking about your Pontiac Grand Voyager. Unfortunately, it sounds like you may be losing fluid a little too quickly for the BlueDevil Transmission Sealer to be effective. It would be kind of tough to say specifically where the leak is coming from, so we recommend bringing the vehicle to a Transmission Specialist for a proper diagnosis.
Hope this helps!

I have an 03 Pontiac grand am, when I put transmission fluid in it leaks out of the axle shaft and we just put a new seal on and its still leaking. What would cause that? Also would the blue devil be something to try?

Thank you for asking about your Pontiac Grand Am. As long as you are not losing transmission fluid too quickly, you would be a great candidate for the BlueDevil Transmission Sealer. You will be using one oz. of the product per quart of fluid in the system, and should start to see results after about 100-200 miles of driving.

I have a 2010 Buick LaCrosse. I put transmission flood in it because it was running rough and when I checked it had no flood. It was fine when I ran it it went around the block. But when I took a longer ride and the car warmed up a little, I turned the car off at my destination and when I got back in the car the flood was all over the ground.. what could be the problem?
Dawn-
It sounds like you have a severe leak coming from your transmission. Due to how quickly you are losing fluid we can not recommend our product as it would be lost before you gained any benefit from it.
We recommend that the vehicle is taken in to be looked at by a transmission specialist.
Thank you!

I have a 06 altima I just had front pump seal replaced meanwhile I had him replace two Axel seals well the day after I picked it up it was pouring like it was . He said he glued the seal in because it was almost out of transmission. So now I’ve paid the mechanic to fix this problem I still have problem and no money! Any thoughts to what this could be?
Kristen,
Thanks for your question about your Altima. Our encouragement would be to take your vehicle back to the mechanic who did the work and ask him to check his work and get things right. If you’ve got new seals and your transmission is still pouring fluid it is possible that you’ve got some bad bearings in your transmission. If a bearing is bad it will allow the shafts to wobble and fluid to come out of even new seals. The other possibility is that your shafts are worn down from use and even a new seal cannot create a good seal and you’ll need output shafts as well. Hopefully, your mechanic simply used an incorrect part or installed something incorrectly and it will be an easy fix.
Thanks again for your question!

Hello. My ford escape car transmission oil overflow and leak out when driving and when accelerated it produces an unusual sharp sound like a miss firing sort from the exhaust pipe. Please help me out .
Pius,
Thanks for your question about your Ford Escape. The first step in stopping your oil leak would be to identify where it is coming from. Using a flashlight, start at the bottom of your engine and work your way up until you don’t see anymore more evidence of a leak. At the highest point, look for a gasket, hose or seal that the oil might be coming from. If the leak is from a gasket or a seal, you can use BlueDevil Oil Stop Leak (available here: http://store.gobdp.com/oil-stop-leak-49499/) to stop the leak.
As for the sharp sound you’re hearing it could indeed be a misfire or a backfire. If either of these things is happening, your car should have a check engine light on. If so, we would recommend taking your car to your local auto parts store and having them read your engine codes to help you figure out whats going on. If you don’t have a check engine light on, we would recommend starting with a good tune up including changing your engine air filter, fuel filter, spark plugs and using BlueDevil Fuel System Cleaner (available here: http://store.gobdp.com/fuel-system-cleaner-00202/) to make sure your car is running at peak performance.
Thanks again for your question!

Hi I have a 2004 Chevy Classic and I’ve been noticing that my vehicle is humming and I’ve noticed on my driveway that I have two different spots very close to each other of transmission fluid not very big spots do you think your product will work in my case I added a half a quart of transmission fluid today the transmission is not humming no more but I am still leaking

I have a Toyota Camry 2008 model. After driving a long distance, i discovered there was a huge spill of transmission fluid under the car which spilled on the exhaust pipe. Could this fault be fixed with the application of bluedevil transmission sealer?
Agbeniyi-
Thank you for asking about your Toyota Camry. Based on your description, it sounds like you are losing fluid a little too quickly for the product to be affective, unfortunately. The BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping from the system. A hard part repair may be your best option.
Thank you!

After reading about this product I tried it and wow it worked so well . Still driving as good as it did when first brought the car now my son is driving it hopefully for a long time without trans having to be rebuilt . Thanks again …
Nate-
Thank you for the wonderful feedback! Once the product seals, it would be a permanent seal, so you should be good to go at this point. We appreciate your positive review.

Quick question:
I have a 2007 Nissan Maxima that I use on a 1/4 mile track. The car is all stock and it is an amateur race where you just gut the car out and race. The engine and tranny are all stock. Yesterday during the race tranny fluid leaked all over the place and while I was racing. I smelled the fluid on the exhaust. When the race came to a stop I was unable to move. I was pushed off the track and after sitting for a while I started the car it it was able to drive itself onto the trailer. After a few minutes the tranny was slipping again. We looked at the tranny and it looks like the leak was from somewhere on top of the tranny. There is a hose that is unhooked on the top (breather hose???? for tranny). Not sure if the fluid came out of here. I put only a quart of fluid in and I was able to back the car down my driveway into the garage. I plan on starting the car this week and try and diagnose the problem. I looked under the car and I do not see any leaks. Is it possible the tranny was overfilled? What should I do with that hose?etc. What would cause the car not to go in gear? THanks
Sorry for posting again I just want to clarify from above comment:
The car does move now. After the race I put about 1 quart in and I was able to drive it into my driveway. 1 quart seems like not a lot of fluid to have to add back in. It seems to be going into gear fine now. I will test it this week. I am just worried it might happen again in next race.
FG,
Thanks for your question about your 2007 Maxima. It would be surprising if 1 quart of fluid was low enough to get the car not to move, but a low transmission fluid level would cause your car not to move. Your transmission does likely have a breather hose and if you were racing it could have overheated the transmission fluid, which would cause it to expand and possibly overflow. The other hoses on your transmission could be going to a transmission cooler, possibly integral with the radiator so you could check those hoses for leaks as well.
Thanks again for your question!

Would you recommend this product for a recently purchased used vehicle that seems to be having no issues? In other words, would this be preventive for engine or transmission problems in an older vehicle?
PeterB-
Yes, the BlueDevil Transmission Sealer can be used as a preventative maintenance. It will revitalize and recondition the rubber seals in the system to get them back to their original state. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I drive a 88 Chevy van. Only drive about 2 times a month. It is a handicapped accessible van with only 75000 miles. About a year ago I put it in reverse and lost about a pint of transmission fluid. None since then. Yesterday I put it in reverse and lost about another pint. Drove it about 100 miles to the Dr and didn’t lose any more. Do you know what would cause it to only lose it when put in reverse?
Floyd,
Thanks for your question about your Chevy van. Only losing fluid in reverse is definitely an odd symptom. It would help if you can tell where the leak is coming from. The most common place for a transmission fluid leak is the output shaft seal. Since your van is older with low miles that seal could be old and hard. When you put it into reverse the shaft spins the opposite direction so it could stretch that seal allowing for a bit of a leak. If that is the case, BlueDevil Transmission Sealer can soften that seal and stop that leak.
Thanks again for your question!

I have a ’71 Chevy G10 van with a rebuilt TH350. The van spends a lot of time sitting without use and my mechanic informed me that I was low on transmission fluid. Upon picking the van up I noticed that fluid was leaking from the rear of the transmission pan. I park the van on a forward grade of approx. 5%, my mechanic made some comment about fluid leaking from the torque converter over time. The transmission shifts firm and goes into gear positively. How should I proceed?
Van Little-
Thank you for asking about your Chevy G10. Based on your description, we recommend using the BlueDevil Transmission Sealer (https://store.gobdp.com/transmission-sealer-00236/).

I have a 2006 Chrysler town and country I am leaking transmission fluid along to front end of my car. Looks like just beneath the radiator. It’s drops of it along the whole front not just one spot. What do you think is causing this?
Stephanie-
Thank you for asking about your Chrysler Town & Country. Based on your description, it would be difficult to say exactly where the leak is coming from. The most common areas where leaks can occur would be the transmission pan gasket, cooler lines or one of the converter seals. If the leak you are experiencing is not more than a seep or a light drip, you would be a good candidate for the BlueDevil Transmission Sealer (https://store.gobdp.com/transmission-sealer-00236/). Add one oz. of the product per quart of fluid in the system, and expect to see results after approximately 100-200 miles of driving.

Hi BDP Team,
I am using Honda Accord about 60000+ Kilo meters. Last 2 days I was experiencing engine raise while accelerating in some unusual manner. Today when I was driving, it does not pick in line with gear change and finally I was not able to shift the gear. I through it may be due to Clutch plate damage.I have toyed the vehicle to a Garage where they said there is fluid leak in the back. They said it transmission needs grounding to repair the Oil leak.
Let me know whether this can be solved by BDP ?.
Thanks & Regards
Kishor
Krishor-
Thank you for asking about your Honda Accord. Are you having the same shifting issues when the fluid is topped off to the proper level? Keep in mind, you will need to be able to drive the vehicle in order to get the benefit of using the product. BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping. As long as you are not losing fluid too quickly, and shifting is fine with the fluid topped off, you would be a good candidate for the product.
Thank you!
