Having a leak in your transmission can be a dangerous thing. It may seem like a few drips here and there won’t end up being a problem, but let’s do the math. Assuming the puddle is big enough for you to notice, let’s say a puddle about the size of a dollar bill overnight, your transmission would lose about a quart of fluid every 10 days. If your transmission holds 4 quarts of oil in the pan, then that’s a quarter of your fluid capacity gone in 10 days, and almost all of it gone in a month!
Having low transmission fluid can cause a lot of expensive and frustrating problems. First, the lack of fluid can cause higher than usually transmission temperatures. The fluid in the transmission helps car heat away from friction points. Less fluid means a higher temperature and a reduced capacity to cool the friction components allowing them to wear faster and potentially fail sooner. An inadequate transmission fluid level also can mean poor lubrication if there is not enough fluid to reach the critical areas of the transmission also causing premature wear. Lastly, a low transmission fluid level can cause dangerous drivability issues for your vehicle. Transmission fluid is the high pressure operating fluid that cause gear smooth and accurate gear changes. A low level can allow your vehicle to behave unpredictably and possibly even dangerously.
If you maintain your vehicle well and notice the transmission fluid leak, you may consider continuing to top of the transmission fluid level ensuring you don’t end up damaging your transmission due to a low fluid level. Transmission fluid can range from 8$ a quart up to $15 a quart or more, so every 10 days you’re having to spend that much in replacement fluid, not to mention the time it takes to fill and check your fluid level every few days and continue to go to the auto parts store to purchase more fluid, funnels and clean up materials.
The most common leak points on automatic transmissions are the input and output shaft seals. There is a shaft on the front of the transmission that slides either into the clutch plate or the torque converter that has splines on it. This shaft transfers power from the engine to the gears in the transmission and will have an oil seal around it. The output shaft similarly will have a seal that goes around the shaft, a slip yoke or the CV axles depending on the type of vehicle. As these shafts or axles spin while your drive, over time they can start to wear down the seals around them. Also, old fluid, low fluid or a lack of driving can cause these seals to dry out, harden or crack causing leaks.
Replacing these seals can often be a costly venture, and depending on the age of your vehicle and how long you intend to continue driving it, it may not be cost effective to replace them entirely.
You do however have another option. Add BlueDevil Transmission Sealer next time you top off your automatic transmission fluid. BlueDevil Transmission Sealer is specially formulated to restore the seals on the input and output shafts of your transmission to their original size and soft condition to permanently seal your transmission leak. BlueDevil Transmission Sealer is guaranteed to seal your transmission leak! Depending on the speed of your transmission leak BlueDevil Transmission Sealer can pay for itself in 2 weeks or less by saving you money on replacement transmission fluid.

Yes, the BlueDevil Transmission Sealer would work to seal the leak you have described. You will not need a whole lot of product based on the small capacity. You should add 1 ounce of BlueDevil per every 1 quart of capacity. Expect to notice results after about 100 miles of driving.

What if your friend accidently adds the whole bottle? Is it going to mess the car up?

Do you think I have to put more blue devil? This can help me to save my car.

I have a 1997 Honda Accord with a bad front seal. The transmission fluid comes out as fast as you put it in. Will this product work on it and if so how many times will you have to add transmission fluid until it stops leaking?

Unfortunately, it sounds like the leak you have is too larger than what the product is intended for. If you are losing fluid just as quickly as you add it, you would lose the product just as quickly. A hard part repair may be your best option.

Roger-
The proper amount of BlueDevil Transmission Sealer to add to a 14 quart system would be 14 oz. You really only want to add the recommended amount of the product. However, the product does not harden or thicken in anyway, so it would not have any adverse affects on the system.

My transmission pan is overtightened and the gasket is smooshing out the sides some. It looks like it’s made of cardboard, as others have also mentioned elsewhere. OEM 1984 mediumduty truck. The plate seems nearly impossible to remove. Ever heard of a transmission stopleak fixing a leaky cardboard paper gasket oozing out the sides due. To overtorque? How long can the seal last?
John-
Unfortunately, we do not manufacture a product intended to treat cardboard or paper. Our BlueDevil Transmission Sealer is only intended for rubber seals/gaskets. Having the the gasket replaced sounds like it would be your best bet.

Typically, you would start to see results after about 100-200 miles of driving. It does not have to be a continuous drive. You are fine to drive in 5,10 mile intervals, here and there.

I Have a trans leak caused by bushing wear in my 2004 cad deville.Tech says it needs third clutch housing replaced($1600)
Friends told me about Blue Devil for head gaskets.Will your trans sealer correct my problem
Sonny,
Thanks for your question about your Cadillac Deville. If your leak is still just a dripping leak for a gasket or seal then BlueDevil Transmission Sealer will restore the seal and stop your leak. You need to make sure to replace the worn bushing to get everything back into alignment before you try to seal your leak.
Thanks again for your question!
-BD Auto Pro
I have a 97 Ford Taurus I don’t see a Leck or anything but it takes a long time to catch gear I already put 4 bottles of transmission fluid in it
Dwayne-
The best place to start would be to change your transmission fluid and filter and then double check to make sure the fluid level is correct. Having the transmission fluid level too high or too low can cause the transmission to act up and not shift properly.
If you are still experiencing the hard shifting after changing the fluid and filter and topping to to the proper level then you may want to have your Taurus looked at by a transmission specialist.
Thanks!

I have a inner seal leak will it work it’s leaking pretty bad
Ashley-
The BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping from the system. Based on your description, you may be losing fluid a little too quickly for the product. Typically you would start to see results after about 100-200 miles of driving. If you would be losing all of your fluid before you got to that point, you would not be able to keep the sealer in the system long enough to get the benefit of it.
Thank you!

Hello I have a 2002 Hyundai elentra. I have a transmission leak and was told that I needed to have my seal replaced. Sometimes I have a puddle of transmission fluid and other times there are just drops. It drives okay.

I have a 1994 Ford Explorer. It is leaking about 1 quart of fluid every 2-1/2 days. Im not ready to have to go thru the extensive labor especially without a lift to the drop the transmission right now inorder to replace the front transmission seal. I wanted to know if your Blue Devil Transmission Sealer would do the job and hopefully save me the grief of having to drop the transmission at this time for a leaking seal. Once again it leaks about 1 quart of transmission fluid every 2 to 3 days, which is a pretty serious leak and costly. Im hope your product will be my savior.
James-
Yes, based on your description we do recommend adding the proper amount of BlueDevil Transmission Sealer to your Explorer. You should add 1 ounce of BlueDevil per every 1 quart of fluid capacity. Once the product is added you can expect to start seeing results after about 100 miles of driving.

I posted on your blog just two days ago. I went ahead and purchased the Blue Devil Transmissin sealer that very same morning. I added the proper amount of the product as instructed and drove the car 250 miles sense then. Right away I seen that the puddle of tansmission fluid that was being left on my drive way was getting less and less. This morning I was parked in a new spot over night and now would’nt you know, I didnt find one bit of transmission fluid on the ground under the car.
This is great news for me and I hope it will last for a long while. Im impressed considering I have already tried many different brands of transmission sealers that are on the shelves with no results to fix the problem. Just more wasted money was all. If I had only tried Blue Devil first I would have saved more money. I deffinitly will tell everyone I know that has these type of leaks to try Blue Devil first to fix there problems. I cant thank the people who came up with and made this product enough. Thank You So Very Much. Sincerly, James Muir.
A Very Satisfied Consumer.

Thank you for asking about your Cadillac Deville. Based on your description, we recommend using the BlueDevil Oil Stop Leak. The Oil Stop Leak is a universal application and would treat leaks coming from the oil pan gasket, valve cover seal, rear main seal, transmission, etc. As long as you are not losing fluid too quickly, you would be a good candidate for the product.

Well, I meant the trans, anyway I put 8oz. In & drove 140 miles. The cars been sitting now for 24 hrs & I $h!+ you not there’s not a drop on the floor!
I am genuinely shocked! For anyone who has a bad tranny leak, be advised, my case / pans are not cracked, the tranny was rebuilt @ 2 years ago, & operating very well. I think my gaskets started cracking after sitting in below freezing temp at @ 8000 ft above sea level. My question to bdp at this point, how does the tranny seal effect the oil & the mechanics within the transmission? How can you prove it?
Mark-
Thank you for the excellent feedback, we are glad the BlueDevil Transmission Sealer was able to stop the leak in your vehicle! The product is only affecting the rubbers in the system. It is revitalizing and reconditioning the rubber seals or gasket, and will swell them up or expand them back to their original state. The product would not have any affect on the oil or the mechanics within the transmission itself.
Thank you!

I have a leak in the transfer case of my 4×4. The transfer case uses 75w-90 gear oil. The leak appears to be coming from the gasket between the transfer case halves (the case is splittable when disassembled). I believe the gasket is paper, not rubber. The case is NOT leaking from the rubber input or output shaft seals. Will the transmission sealer work on the paper gasket between the transfer case halves?

I have a 2002 audi a4 Quattro the other day I was backing out and the car died an I stared it and drove about 5 miles and looked back smoke was barreling out the back from the fluid being lost looked under and transmission was pouring out fluid looked under and it was coming out from between the bellhousing and engian block so I’m thinking blew the input shaft seal you think this might help I reall don’t want to pull the trans
Eric,
Thanks for your question about your Audi A4. The real question for us is why your car started leaking so much fluid so quickly. If you’ve had a slow leak for a long time that has been getting steadily worse then you might try using BlueDevil Transmission Sealer to stop the leak. If the leak has suddenly gotten worse it may be an indication of a bigger problem like a worn bearing allowing the shaft to wobble or or something else misaligned so it may be wise to remove and inspect the transmission to ensure there aren’t any bigger problems.
Thanks again for your question!

The capacity of the Transmission on your Chevy Trailblazer is 11.2 quarts. We recommend adding 11 ounces of BlueDevil Transmission Sealer to properly treat your vehicle. Expect to start seeing results after about 100 miles of driving.
Thanks!

I have a 2004 Dodge Stratus, 2.7 V6 with 260,000 miles on it. I appears my transmission pan is leaking, will this seal that long enough until I can get my car in the shop to have the seal?d
Debbie-
Thank you for asking about your Dodge Stratus. As long as you are not losing transmission fluid too quickly, you would be a great candidate for the BlueDevil Transmission Sealer. Typically, you would start to see results after about 100-200 miles of driving.
Thank you!

I got a question for you and Blue Devil…I have a 1994 gmc sonoma the transmission started leaking terribly on my way to work one night. I wasn’t sure what the problem was (still don’t). It is leaking quite a lot of fluid between front of pan and cover plate on trans. My question is: will Blue Devil seal this problem? p.s. it only leaks when engine is running
Chuck-
Thank you for asking about your GMC Sonoma. Based on your description, you may be losing fluid a little too quickly for the BlueDevil Transmission Sealer to be effective. Typically, you would start to see improvement after about 100-200 miles of driving. Unfortunately, it sounds like you may lose the product before it would get a chance to seal. A hard part repair may be your best option.
Thank you!

do you think if i add more and more product as i add trans fluid it might repair it in 100-200 miles?
1 ounce to 1 quart trans fluid?
Chuck-
You really only want to add the recommended amount of the product. You will use 1 oz. of the product per quart of fluid in the system. Unfortunately, if you are losing fluid too quickly, you would lose the product just as quickly, and wouldn’t really be able to keep it in the system long enough in order to get the benefit of using the product. Feel free to contact our technical support line at 888-863-0426 with any other questions.
Thank you!

KD-
Thank you for asking about your Ford Explorer. Based on your description, you may be losing fluid a little too quickly for the BlueDevil Transmission Sealer. Typically, you would start to see improvement after about 100-200 miles of driving with the product. Unfortunately, you may be losing the product too quickly in order to really get the benefit of using it. A hard part repair may be your best option.

I have an 01 ford Taurus. I started noticing it a few days ago but don’t know how long it has been leaking for. Today as I was driving it, it started jumping hard trying to get into gear, I’m assuming due to low fluid levels. I noticed a puddle because I immediately stopped driving it and had it towed home. Would this help fix the leak?
Ashley-
Thank you for asking about your Ford Taurus. Unfortunately, it sounds 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 results after about 100-200 miles of driving. If you are losing fluid to the point where you would be losing the product before you got to 100-200 miles of driving, you wouldn’t really be able to keep the product in the system long enough in order to get the benefit of using it. A hard part repair may be your best option.

My ’03 Infiniti g35 Sedan started revving high all of a sudden and sometimes not catching the gear. I have flushed the transmission fluid completely but as soon as my wife drove it to Walmart (which is only 1 mile from home) it started acting how it did before I flushed it and the Check Engine Light came on. The place said I had a small oil leak but I never see any spots in my driveway so it must be very small if there is one. Will Blue Devil work in my situation?
David-
Thank you for asking about your Infiniti g35. Based on your description, we recommend using the BlueDevil Oil Stop Leak, found here on our website: http://store.gobdp.com/oil-stop-leak-49499/. The BlueDevil Oil Stop Leak is more concentrated and is the universal application that will work for oil pan leaks, rear main leaks, valve cover gasket leaks, etc. Being that it doesn’t sound like you’re exactly sure where the leak is coming from, the Oil Stop Leak is what you would want to use.
Thank you!

I’m wondering will blue devil seal the hole in my transmission?also will it hurt my transmission?it’s not a big hole and it ain’t to long happened my car is a 2001 saturn sedan sl2 please help
Roachelle-
Thank you for asking about your Saturn. The BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping from the system. As long as you are not losing fluid too quickly, you would be a great candidate for the product. The product does not harden or thicken in anyway, so it will not have any adverse affect on the system.
Thank you!

I have a 2002 gmc Jimmy sls 4×4, I have a leak coming from the transmission pan gasket. Will the product work for my problem, and how much should I use since I don’t know how much fluid in total it takes to fill my system? Also, when I put more transmission fluid in to refill the system, do I need to add more blue devil then as well?
Jamie-
Thank you for asking about your GMC Jimmy. It appears your vehicle has about an 11 quart capacity for transmission fluid, so you would want to use about 11 oz. of the product. You should only need to add the product once. Be sure to leave enough room for the recommended amount of the product.
Thank you!

Well
I have an 04 sienna and the transmission started to leak from the seal at the torque converter software I went and replaced the seal thinking it will fix the problem but I assembled it and its still leaking so I thought maybe the seal isn’t tight enough so I got a new seal and just shortened the spring to make the seal a little tighter. Put that all together and again it’s leaking I’m just alreadyet running out of ideas what it can be. Also it only leaks when the car is in gear reverse or forward… doesn’t leak when in park… what can it be?
Mike-
Thank you for asking about your Toyota Sienna. Based on your description, we recommend using the BlueDevil Transmission Sealer http://store.gobdp.com/transmission-sealer-00236/. Typically, you should expect to see results after about 100-200 miles of driving.

I have a 2006 Subaru Legacy 2.5i 4T. Is Blue Devil safe to use in CVT transmissions? Thanks
Bobby-
Thank you for asking about your Subaru Legacy. Unfortunately, BlueDevil Transmission Sealer is not compatible for use in CVT transmissions. We do not manufacture a product that will work on those types of transmissions. CVT transmissions require a very specific type of transmission fluid that can not be contaminated with any other type of fluid.
Thank you!

I’ve got a World Class T5 transmission from a 1991 V8 Camaro. Is BlueDevil sealer suitable for this car?
It is not leaking from the input or output shaft. It is leaking from the seam where two pieces of the case are bolted together with RTV. It leaks a couple drips every time I drive it. And it only leaks when driving it.
Will it seal this area?
Salvador-
Based on the location of your leak we do not recommend using BlueDevil Transmission Sealer. BlueDevil Transmission Sealer is specifically designed to stop fluid loss coming from any rubber seal or gasket but not from a seam.
Thank you!

I have a 2WD 97 Chevy s10 pickup truck with 2 leaks in the transmission one of the leaks is from the front seal and the other one is coming from gasket on the pan the leaks really aren’t that bad when driving around town but they get extremely bad if I drive on the highway will Blue Devil Transmission Sealer work for the leaks my truck is having?
Please let me know ASAP. I’d really appreciate it. The truck is the only thing I have to get around in and I really can’t afford to get a new car or the transmission repaired do to I’m on disability. Thanks in advance.
