A transmission leak isn’t the worst malady for a vehicle to have, but it’s still best to avoid them when possible. Most engines can hold four to six quarts of oil. Transitions, meanwhile, only hold one-and-a-half to three quarts of fluid. So, even a small leak can make a difference extremely quickly quickly. Not to mention, a leak can cost you between 100 and 200 dollars if you take your car to a shop (If you have to replace your transmission you’re looking at a lot more). Luckily, you can avoid a trip to the mechanic completely by following our guide. Everything you need to know about how to fix a transmission leak is right here! Additionally, BlueDevil transmission sealer is designed to stop transmission leaks in their tracks and get your transition back in working order. Find out more about our stop-leak product below!
Stop Your Transmission Leak Fast!
How to Fix a Transmission Leak
With a manual transmission, there are really only two things that can cause a transmission to fail prematurely other than normal wear and tear: poor driving habits and an improper level/type of transmission fluid. If you have issues with your automatic transmission, check out our blog on how to identify and fix a hard shifting automatic transmission.
Where Is the Leak Coming From?
If you’ve noticed transmission fluid leaking from the front of the car or sitting under your parked car, you’ve most likely got a leak. If you’re thinking about fixing the leak by hand, the first thing you need to do is locate the leak. Here are the most common places you’ll find a leak in your transmission:
- Cooler Lines
- Dipstick tube O-ring
- Input seal
- Output seal(s)
Cooler Lines
The most common transmission fluid leak location is from the transmission cooler lines. Every automatic transmission pumps the fluid either through a cooler in the vehicle’s radiator, an auxiliary cooler, or both to help warm the fluid when you first start driving and to help cool the fluid once it has reached normal operating temperatures. The lines to and from these coolers are simply rubber hoses that can leak at the connection and crimp points. It is usually easiest to find where these lines exit your transmission then follow them up to the front of your vehicle looking for leaks. If you find a leak the best thing to do is replace the line.
Dipstick Tube O-ring
The dipstick you use to measure the fluid level in your transmission fits into a tube or standpipe. That tube has an o-ring where it enters the transmission and as that o-ring gets old and dried out it can allow fluid to sneak past it and leak out. Dipstick tube o-rings often leak intermittently and more when your vehicle is parked on a hill or slope. Replacing this o-ring is often a very easy do-it-yourself job so you may consider tackling it if you find this as your leak location.
Input Shaft Seal
This is the least common leak point in any transmission because it is hidden behind inside the bellhousing where it is safe from dirt, dust and other things that destroy seals. If your input shaft seal is leaking, then you will see transmission fluid dripping from the front of your bellhousing. IReplacing the seal will require removing your transmission which can be an expensive job. If that doesn’t make sense for your or your vehicle, use BlueDevil Transmission Sealer to restore that seal and stop the leak.
Output Shaft Seal
Leaking output shaft seals is a very common leak point. If you have a transmission fluid leak at the output shaft seal you will see evidence of fluid leaks where your CV axle exits your transmission or where the driveshaft exits the transmission on a rear wheel drive vehicle. Replacing these seals does not require removing the transmission so check with your mechanic to see if that makes sense for you. If not, BlueDevil Transmission Sealer can seal this leak as well!
How to Quickly Fix Any Transmission Leak
Transmission Leaks can be costly issues that leave your car in the shop for days. With BlueDevil Transmission Sealer, they don’t have to be. Our expertly crafted sealing solution is designed to restore your transmission and seal leaks fast! For a fraction of the price and time that a visit to your nearest service shop will cost you, our sealant will put kick your transmission back into shape. Learn more below!

Does it have any harmful effect to the transmission, like, should I flush the transmission after the leak is sealed and replace the fluid, so that the residual sealer is purged? I’ve heard of other brands gumming up in the gears if the oil with the sealer in it wasn’t flushed.
Brian-
No, the BlueDevil Transmission Sealer will not harm the transmission or any other components in any way. The BlueDevil will not thicken or harden at any point. The Transmission Sealer can be left in for the life of the transmission fluid.
You should add 1 ounce of BlueDevil Transmission Sealer to every 1 quart of fluid capacity.

How to install sealer in a 2007 Toyota Prius? Is this a do it yourself job?
JoLynne-
The BlueDevil Transmission Sealer is an easy, do-it-yourself product. As long as you can locate the transmission fluid cap, you would be able to use the product. If the fluid level is currently at the max line, you would need to drain/siphon fluid out to allow room for the recommended amount of BlueDevil Transmission Sealer (1 oz. of the product per quart of transmission fluid). This would be the only reason you may need additional help. Feel free to contact our technical support line at 888-863-0426 with any other questions.

I have a 2002 Audi tt Quattro 225hp 6 Speed Transmission. I removed the tranny to replace the clutch and separated the front differential from the transmission and replaced the 3 seals connecting them with OEM products, however I’m noticing some seeping from those seals. What is the capacity of the transmission fluid (synthetic 75W 90) so I can purchase your product and add the correct amount. The fluid runs through the transmission and differential. Will it be safe for this type of setup?. Thank You.
Frank,
Thanks for your question about your Audi. First we would recommend checking the torque specs on the bolts you tightened around those gaskets to make sure everything is tightened properly. If you still have leaks after that, you can add BlueDevil Transmission Sealer along with the gear oil for your transmission and differential. BlueDevil Transmission Sealer will not significantly raise the fluid level in your transmission so you can add it safely to your transmission now.
Thanks again for your question!

My 1994 Mazda B3000 pickup has a manual transmission. However, it uses automatic transmission fluid. The transmission has a capacity of three quarts, and it leaks at a rate of around one quart every 4-6 weeks. The vehicle only has about 105,000 miles on it, so there’s a good chance that it set idle for an extended period of time.
I’m interested in trying your product, by I need to know…
1. Will it work on automatic transmission fluid in a standard transmission?
2. If so, would it be able to stop this rate of leakage?
Thanks.
Joey-
Yes, BlueDevil Transmission Sealer will work with Automatic Transmission Fluid in a standard transmission. Based on the capacity, you should use 3 ounces of BlueDevil to treat the Mazda. The leak you have is fairly large but not too large fro what BlueDevil is intended to fix. Once the product is added you can expect to start seeing results after about 100 miles of driving.

Question: 94 f150 new clutch, peddle became soft a month in. Added brake fluid to top it off did this once a week then became an everyday occurrance, then I couldn’t shift at alk. Thought it needed to be bled but then noticed when you push the peddle to the floor I saw the fluid poor out the center of the bell housing. The seal is leaking correct? Would your product help at least get it home? It’s stuck in a parking lot about 5 mikes away. To be honest, this would be the cheapest fix for me. Not made of money so cheap is the only way for me. Thank you for reading!
Jaelynn-
Thank you for asking about your Ford F-150. Unfortunately, it sounds like you are losing fluid a little too quickly for the BlueDevil Transmission Sealer to be affective. Typically with the product, you would start to see results after about 100-200 miles of driving. If you are losing fluid to the extent that you would lose your fluid capacity before 100-200 miles, then the leak you have may be a little too extreme. A hard part repair may be your best option.

Hi There
I have a 1971 Triumph TR6 with a 4 speed manual gearbox and A type overdrive. The gearbox was recently overhauled however I now find that it has a leak from one of the the overdrive seals. Its a huge job to get to this and basically requires gearbox out. The gearbox is filled with 2.7litres (2.85 quarts ?) of Penrite HPR 30 engine oil which is SAE 20W-60. Is the Blue Devil Transmission Sealer suitable for this situation and how much should be used if suitable. Are there any negative side effects in this application ?
Regards Spiro Agius – Melbourne Australia
Spiro-
Thank you for asking about your Triumph TR6. Yes, the BlueDevil Transmission Sealer would be safe and compatible to use for this type of application.
