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 that your car is leaking oil and it fits this description, 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!
-BD Auto Pro

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!

I was driving one day in my Nissan Altima & then i won’t not drive more for 15sec.I turned my car Off & then i started my car and it drove perfectly.I went to NAPA & they told me that I had no transmission fluid more ,they put transmission fluid for me.It have been 1week all & everyday in the morning i see a little leak of transmission leak (5 cm a 5 cm) .But during the day it doesn’t leak ,would this work?
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.

Skyler-
Yes, the BlueDevil Transmission Sealer is made specifically for stopping transmission fluid leaks. It sounds like you are catching the leak fairly early so you should have no problem stopping it with BlueDevil. You should be adding 1 ounce of BlueDevil per every 1 quart of transmission capacity.

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!

Yes, it would be recommended to add the BlueDevil Transmission Sealer; you should add 1 ounce of BlueDevil per every 1 quart of capacity.

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? Mine is an old (’89) 5 speed, not exactly sure of leak(s) locations, but leak might be at rate of about 2 oz a week (?). sound potentially in the range of Blue Devil’s ability to remedy? thanks!
Gary-
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.

The BlueDevil Transmission Sealer is not intended to stop a fluid leak coming from the actual dipstick. We recommend having it replaced.

Have a 1996 Chevy Impala SS – all original with 4L60E transmission. Has 62000 miles on it. Has developed a small transmission fluid leak. It sits in garage most of time. After a month a small amount of fluid witting on plastic under transmission. I want to use your product but need to make sure it will not cause any damage. Also do you think it will work.
