Have you ever looked under your car and found that it was leaking some sort of fluid that you didn’t even know your car had in it? Most of us know engine oil is brown or black, coolant is usually green, but you usually don’t see a red fluid. Automatic transmission fluid is still oil, but usually thinner than engine or gear oil and tinted red in color. If you’ve found this under your car, then you most likely have a transmission leak.
How to identify a transmission leak
To check for a leak in your automatic transmission, you can do a visual inspection to try and find the leak point. Here are some of the most likely places to check:
Automatic Transmission Leak Points:
- Drive shaft seal
- Transmission pan seal
- Input shaft seal
- Valve body seal
Checking your transmission fluid level can also be confusing. Unlike your engine oil your transmission fluid level needs to be checked while your vehicle is parked and running. The dip stick will often have a red cap on it and be towards the rear of the engine near the firewall. There will be 2 different level indications on the dipstick, one for when the fluid is cool, and one for when the fluid is warm. Your automatic transmission fluid level should indicate in the “cold” range when you first start your vehicle and haven’t yet driven. It should indicate inside the “hot” range after you’ve driven your vehicle relatively hard, for example, up a long hill, towing, or with the transmission in a lower gear to increase engine RPM.
Once you’ve identified your leak either by a low fluid level or visual inspection, the next question is: How much will this cost to fix? If you let your transmission operate with a low fluid level, it will cause it to start shifting hard, but eventually will cause permanent damage and could cost thousands to replace.
How to fix a transmission leak and avoid high transmission leak repair costs
If you’ve ever had to learn the hard way just how much it costs to fix a transmission leak you’re well aware for the need to avoid that expense again. The best way to prevent these high transmission repair costs, and avoid having to add transmission fluid every few days to your vehicle is to use BlueDevil Transmission Sealer. BlueDevil Transmission sealer is added directly to your automatic transmission with no need to do a fluid change. Just add BlueDevil Transmission Sealer and it will work as you drive to seal your leak. As you drive, Transmission Sealer will be absorbed into the worn out seals and gaskets in your transmission restoring them to their original size and sealing properties.
You can purchase BlueDevil Transmission Sealer from the manufacturer here: Transmission Sealer, or find it at your local parts stores like:
- Bennett Auto Supply
- Prime Automotive
- O’Reilly Auto Parts
- Pepboys
- Car Quest Auto Parts
- Advance Auto Parts
- NAPA

My 2003 Chevy Avalanche just stopped accelerating while driving, when I pulled the truck over I noticed all of the transmission fluid has leaked out. I purchased a brand new transmission in 2009 and I don’t think I should need a new one so soon. Do you think simply adding more fluid could fix the prob or are there any other cheaper alternatives other than purchasing a new transmission.?
Anthony-
Thank you for asking about your Chevy Avalanche. Unfortunately, it does not sound like simply adding more fluid would correct the problem. We recommend using the BlueDevil Transmission Sealer, http://store.gobdp.com/transmission-sealer-00236/. You would fill the system with transmission fluid, leaving just enough room for the recommended amount of the product. You will be using one oz. of the product per quart of fluid in the system. You should expect to see results after about 100-200 miles of driving.
Thank you!

I have a Ford F-150 2003 and it’s leaking a red liquid substance underneath my truck how will I able to fix that on my own then taking it to a mechanic.
Christian,
Thanks for your question about your Ford F-150. If the fluid is red then on your truck it would either be power steering fluid or transmission fluid. Your transmission is back behind your motor so if it is leaking you would most likely see drips about in the middle of your truck. Your power steering system is in front of your motor so if you see drips up by the wheels or towards the front of your truck. If you look underneath and find out where the leak is, simply add the appropriate leak stop product to that component and you’ll be on your way to fixing your issue!
Thanks again for your question!

Penny-
I assume you are referring to a transmission fluid leak. If that is the case then we recommend adding the proper amount of BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/). Based on the transmission capacity of your Ford Escape you should add 10 ounces of BlueDevil.

I have 1997 dodge ram 1500 2 wheel drive 5.9 letters. I started having issues with the transmission. I have noticed that every now and then the reverse gear will not kick in. If I drive it forward a bit, then reverse it, it will work. I went underneath the truck and noticed that the transmission pan is a wet. It has been leaking fluid. What do you recommend I do?
BlueDevil Transmission Sealer would be appropriate to stop your leak. The reason the transmission may be hesitating is because of the fluid being to low.
When you add the product, be sure to use one ounce of BlueDevil per one quart of fluid capacity.
will adding more then one per quart make it leak worse ?
Dustin-
Adding more than one oz of the Transmission Sealer per quart of fluid may make the leak worse if you are overfilling the system. It is not one of those things where more of the product would be better, so you really only want to add the recommended amount. Also, you should not overfill the system, as this could cause further issues.
Thank you!

Thanks for your question. It’s difficult to tell from your description what your car is leaking. Try reading our article listing all the different fluids your car uses and how to tell them apart to find out what your car is leaking.

leak coming from the front. Says it could be anything from seals to the differential or more. I can’t afford $650-700 to repair it. Would this sealant really work? And do I wait until the fluid is low before adding it?
Yes, the BlueDevil Transmission Sealer has a very high success rate and will work for the type of leak you have described. You should add 1 ounce of BlueDevil to every 1 quart of transmission fluid (for instance if your vehicle holds 5 quarts of trans fluid then you should add 5 ounces of BlueDevil.

The dealer replaced the transmission on my 2nd vehicle, a 2006 Lincoln Mark LT a few months ago. Now it is sluggish when accelerating all over again and I have been told that it is leaking Diffrential fluid because it leaves transmission fluid on my driveway when I drive it. Is this a seperate issue or should it be covered under the warranty that came with the new transmission? Did they tighten or seal something improperly?
Charla-
I would first confront the dealer that did the transmission work to see if they can cover the repair under warranty. If not, we recommend adding the proper amount of BlueDevil Oil Stop Leak to help stop the leak from your differential. You will not need the whole bottle, add 1 ounce of BlueDevil per 1 quart of fluid; most likely you will only need to add 2 – 3 ounces of BlueDevil.
We hope this helps!

Rosita-
We recommend adding about 8 ounces of the BlueDevil Transmission Sealer to your transmission fluid. The should eliminate the leak and prevent you from having to add transmission fluid in the future. Keep in mind, it may take about 100 miles of driving before you see full results; if you do not drive a whole lot it can take a couple of days.

I have a 2005 GM 3500 truck and the transmission fluid is leaking and I was wondering if the Blue Devil Stop Leak would help to stop the leak.
If so, would one bottle be good enough to stop the leak. Also if I use the product would it affect the vehicle warranty?
Thank you
Roger-
Yes, the BlueDevil Transmission Sealer would be appropriate and safe to use in your GM truck. You may want to check with the dealership on whether or not using this product will affect your warranty status. However, if the vehicle is under warranty you may be able to have the seal replaced at no cost.
If you do end up using the BlueDevil Transmission Sealer you should add about 10 ounces to your transmission fluid.
Thank You!

So the write-up describes your product being for automatics. Do you have another product for manual transmissions, or is this fine for manuals too?

The BlueDevil Transmission Sealer is compatible with automatic and manual transmissions. Keep in mind, you need to add 1 ounce of BlueDevil per every 1 quart of transmission fluid capacity; many times a manual transmission has a smaller capacity.

I have a 1998 Chrysler Sebring convertible and my transmission leaks and we tried tightening the hose but still leaks and are car will stall for a second sometimes because of the leak do you think your product would work
Amber-
If the leak is only coming out around the hose then this will not work. If the leak is coming out around any of the seals or gaskets then then the BlueDevil Transmission Sealer is recommended.

Hi, I drive a 1998 Ford F150 Automatic, I have a very slow transmission leak(10-20 drops overnight). Could BlueDevil Transmission Sealer stop the leak? Also, if BlueDevil doesn’t stop the leak, will it cause any harm to my transmission? I have had my differential done with 4:88 ratio in the rear to assist when towing. Please get back to asap. Thanks.

So I’m at a stop light and have to stop. So I stop. Then when the light runs green I try to go! The rpms go up, but I barely go anywhere. Then all of a sudden a jolt forward and go. Feels like it’s shifting weird. Then, I get home, have my bf check it out. My transmission fluid leaked all out. So we put more tranny fluid in. Went to put it in drive it wouldn’t move. Reverse, wouldn’t move.
Waited a little. Put it in drive, it went forward a little. Put it in reverse and IT WENT FORWARD.
I need help!!!!
Janella-
We recommend that the vehicle is taken to a certified transmission specialist. Based on your description it is likely that the transmission will need to be rebuilt.

I have a ’93 Chevy Silverado, 305 engine and a 4L60E Transmission that keeps leaking form the speed sensor and end shaft. I put a new speed sensor in it and a new rear shaft seal, but still leaks…what you suggest ?
Dennis,
Thanks for your question about your Silverado. We would recommend you use BlueDevil Transmission Sealer (available here: http://store.gobdp.com/transmission-sealer-00236/) to seal those leaks. BlueDevil Transmission Sealer will enlarge the shaft seal to seal that leak and your speed sensor is sealed by an o-ring, which should be sealed by BlueDevil Transmission Sealer as well.
Thanks again for your question!

Embarrassing but my wife added the oil stop leak to the transmission fluid. Do I need to get the transmission fluid flushed now? 08 bone x5 4.0
Shaun-
The BlueDevil Oil Stop Leak is actually a universal application, and can be used in the transmission system. As long as the system was not overfilled and you are not losing fluid too quickly, you should be alright and the product should be able to help seal your leak.
Thank you!
-BDP
I am not sure what the capacity is for a 2006 ford f150 with automatic trans but after driving last night— this morning I have a puddle underneath my truck and I was going to get some blue devil to put in with the additional fluid needed but I got confused on how much to add since I was not sure what the capacity is. can you tell me if I need to add more than one quart should I add say for instance 2 quarts of oil I would add (2 )1oz of the blue devil is this how it works? my truck is old but I need to keep it going as long as I can. thank you
Angela,
Thanks for your question about your F150. You should add enough BlueDevil Transmission Sealer for the total amount of transmission fluid in your truck. Your transmission actually holds over 13 quarts of fluid so you can safely add a full bottle of BlueDevil Transmission Sealer. After you add BlueDevil Transmission Sealer, top off your transmission fluid with the proper type by checking the level on the dipstick. The transmission fluid dipstick is yellow and on the passenger side of your engine bay behind your oil cap. You should check the level with your truck running and in “park”.
Thanks again for your question!

Hi I have a 2007 nissan altima I am leaking transmission fluid. It is a fast leak. Will blue devil work for it?
Marla-
Yes, BlueDevil Transmission Sealer is specifically designed to stop transmission fluid leaks. As long as it is not pouring through transmission fluid there is a very good chance BlueDevil can seal it. Please note that 1 ounce of BlueDevil treats 1 quart of transmission fluid so often times you will not need to add the full 16 ounce bottle (more is not better). Once the product is added you can expect to start seeing results after about 100 miles of driving.
Thank you!

By using the Blue Devil, won”t it keep expanding the seals and make them too soft if product is left in??

Hello, I have a 2000 Chevy Tahoe and have been noticing transmission oil on the ground. And driving out yesterday I heard a crackle sound like I rolled over a water bottle. But I didn’t though, I noticed my truck wasn’t speeding up as fast like when I was pushing on the gas paddle. After returning home right away, I tried to head back out and noticed the truck will not go in reverse but will go forward…..HELP does this mean my transmission is gone? I really hope not!!!! Can I use our product and it will fix the problem…..
Tomika-
Thank you for asking about your Chevy Tahoe. Based on your description, we would recommend using the BlueDevil Transmission Sealer for your leak. You may want to change the transmission fluid in the system first, as any build up or foreign substances in the system could cause transmission issues. You should expect to see results after about 100-200 miles of driving.

I have 2007 Nissan Altima 3.5 cvt transmission is leaking. Is safe use blue Devil To stop leaking…?
Jesus-
Unfortunately, we do not recommend using BlueDevil in a CVT transmission. Continuously Variable Transmissions are very specific as to the type of fluid that is compatible.
Thank you!
-BDP
You say “do not recommend” … Is that because is hasn’t been tested in a CVT or do you know for fact that it is harmful?
Rich-
CVT Transmission require very specific transmission fluid that should not be mixed with anything else. We definitely do not recommend the use of BlueDevil Transmission Sealer in a CVT Transmission.

I have 2006 autonatic kia picanto. I saw leak in my garage don’t know if engine oil or transmission oil. I had just change oil lately. Is blue devil oil will stop the leak? Thank you.
Shirley-
Thank you for asking about your Kia Picanto. Based on your description, the BlueDevil Oil Stop Leak is the product you would want to use. The Oil Stop Leak is a universal application, so that would treat a leaking oil pan gasket, valve cover seal, rear main seal, transmission, power steering, etc. You may want to check your oil and transmission fluid levels prior, as that would be a pretty good indication as to where the leak was coming from.
Hope this helps!

My 2002 jeep grand cherokee leaks red near the front/middle, slightly towards passenger side maybe. I add fluid all the time. It smells bad sometimes and smokes out the front. The other day It started shaking and wouldn’t go good when I got to about 50. Shaking bad. It only did this twice? I’m a no-nothing and can’t afford things. Will BlueDevil help this problem?
Maryanne-
Thank you for asking about your Jeep Grand Cherokee. As long as you are not losing transmission fluid too quickly, you would be a good candidate for the BlueDevil Transmission Sealer. You should make sure the system is filled, leaving just enough room for the recommended amount of the product. You will be using one oz of the product per quart of fluid in the system. Feel free to contact our technical support line at 888=863-0426 with any other questions.

Is this safe for a Mercedes 722.607 transmission? if so the fluid level parameters are very specific and experts state that even a few ounces of transmission fluid over the limit for these transmissions can be damaging….somewhere around 6 or seven ounces of your product is required. Can your product substitute for 136 transmission fluid to bring it up to a desired level on the dip stick without damaging these transmissions?
Tony-
Yes, the BlueDevil Transmission Sealer is compatible in your Mercedes. You are correct in the fact that it is very important for you to not overfill the transmission. The product is not a substitute for your transmission fluid, so if your transmission fluid is already at capacity, you would want to drain enough fluid out in order to add the 6-7 ounces of the product needed for your vehicle. Feel free to contact our technical support line at 888-863-0426 with any other questions.

The front differential on my 1999 Chevy Silverado 4×4 is leaking. Do you have a product that can fix this problem?

Thank you for asking about your Chevy Blazer. 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 to be effective. A hard part repair may be your best option.
Hope this helps!
-BDP
Please help! I was told to add the whole bottle to my transmission. Having trust in the person, i did. What do i do?!

First off, it will not harm the system. If it appears the transmission fluid level is above the “full” mark then you will want to siphon some out as the transmission may act up if it is too full.

April-
Thank you for asking about your Saturn. The BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping from the system. Typically, you should expect to see results after about 100-200 miles of driving. If you are losing transmission fluid to the extent that you would lose your capacity before you got to 200 miles or so of driving, you would more than likely lose the product in that time, and would not be able to keep it in the system long enough in order to get the benefit of using it.

Sabrina-
Thank you for asking about your Dodge Neon. You will be using one oz. of the product per quart of fluid in the system.

I just purchased a 1988 Chevy C1500 Cheyenne pickup truck. It has a slow dripping leak of transmission fluid. Would it be safe to try BlueDevil Transmission Sealer to see if it takes care of the leak before taking it into a mechanic? If okay, how much should I add?
~ Thanks
Nik-

Based on your description, you would be a great candidate for the BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/). You will be adding one oz. of the product per quart of fluid (capacity) in the system and should expect to see results after about 100-200 miles of driving.

Hi I have a 2010 nissan cube with a cvt. There is a small crack in the lip of the pan. will this get me out of a crappy dealership so I can get towed? Possibly 100 ft?
Anna-
Thank you for asking about your Nissan Cube. Unfortunately BlueDevil Transmission Sealer is not compatible to use in CVT transmissions. We do not manufacture a product that will work on that type of transmission. CVT transmissions require a very specific type of transmission fluid that can not be contaminated with any other type of fluid. A hard part repair may be your best option.
Thank you!

I had a small leak in the transmission of my 2007 Honda Odyssey. The fellow at the parts store told me to add the entire 16 oz bottle of your transmission sealant and it would fix the problem. I did jus tthat. But after looking closer at the directions it appears I put too much of your product in. I believe the ATF capacity for the Honda is 8 quarts, so I put 2oz in for each quart. Is this going to be a problem? Should I drain the transmission (3.3 quarts) and replace with straight ATF to dilute the solution? Thanks for your help.
Matt-
Thank your for asking about your Honda Odyssey. Unless the system was overfilled, adding too much of the product wouldn’t have caused any harm, however, it would kind of limit the effectiveness of the product. It is not one of those things where more of the product would be better. Have you driven the vehicle at all since this occurred? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

I found a transmission fluid leak under my car after I got off work. It was near the front of the car close to the driver side. I also saw a small brown oil leak as well, will this help. I have a 2004 Chrysler Sebring. The transmission leak was about a small fist size. Will this help my car?
Karen-
Thank you for asking about your Chrysler Sebring. Based on your description, you would be a great candidate for the BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/). You will use one oz. of the product per quart of fluid in the system.
For the oil leak you are experiencing, we recommend using the BlueDevil Oil Stop Leak (http://store.gobdp.com/oil-stop-leak-49499/). You should expect to see results after about 100-200 miles of driving.

I need clarification on how to use this product. I have a 1989 Chevy Cheyenne pick up truck.
I noticed a huge red puddle under my truck (even after the mechanic “fixed” this issue), and I think most of the transmission fluid has leaked out.
1. How much of the BlueDevil transmission sealer bottle should I add, AND
2. How much new transmission fluid should I add?
I’m so confused and miss driving my truck… thanks for your help!
Lexielou-
Thank you for asking about your Chevy Cheyenne. The system should be filled almost too capacity with transmission fluid, leaving just enough room for the recommended amount of the product. You will use one oz. of the product per quart of fluid in the system. It is important not to overfill the system, so you may want to add the recommended amount of the product first, and then top it off with transmission fluid as needed.
Thank you!

I am finalizing a restoration of a ’69 Chevy C10 with a TH350 transmission. The truck has been driven about 50 miles in the last year however it was off the road undergoing a frame off restoration for several years. No leaks were apparent during the build and test drives or sitting after running. I recently drove it a bit and sat idling for a long while after picking up some parts. I noticed on the end of the 3 mile ride home that the transmission fluid was leaking out substantially. I have refilled and driven a mile or two since with only minor leaks however I don’t want to pull the transmission and replace seals, etc. unless necessary. Would your products help me attempt to avoid this? Note the leak is NOT coming from the linkage, cooler line inputs (capped), transmission pan, dipstick area or any other area where a trail is noticed. It had to have come from under the cover plate meaning front seal, pump or torque converter. The truck still drives and shifts fine…
Keith-
Thank you for asking about your Chevy C10. Based on your description, we do recommend using the BlueDevil Transmission Sealer. The product works by revitalizing and reconditioning the rubber seals/gaskets. As long as you are not losing fluid too quickly, you would be a good candidate for the product. You should expect to see results after approximately 100-200 miles of driving.
Thank you!

I have a 1996 chevy blazer that has a main seal leak that leaks pretty bad. I already have put a lot of money into it and not really feeling like putting even more in to take the transmission out to get it fixed. I was told I have to take the oil pan off and everything. Would blue devil fix the seal or am i screwed?
Kyle-
Thank you for asking about your Chevy Blazer. Based on your description, we recommend using the BlueDevil Rear Main Sealer (https://store.gobdp.com/rear-main-sealer-00234/). As long as the leak is not more than a seep or a light drip, you would be a good candidate for the product. You should expect to see results after approximately 100-200 miles of driving.

Hey!
I have a Honda CRV 2007 with 280,000 miles. It has a front and back main seal transmission leak. I was told with all the leaks it would come out to be over $2000 in repairs which is not worth it considering how many miles it has. The leak I am worrying about it the transmission one since that is costing me a ton in transmission fluids weekly. Is there a possibility this product will work? How much should I put in for two main leaks? Thanks in advance!
Gerri-
Thank you for asking about your Honda CRV. As long as the leaks you are experiencing are not more than a seep or lightly dripping, you would be a good candidate for the BlueDevil Transmission Sealer.
