See What Our Customers Are Saying View More Testimonials
This additive really works! While I was changing my transmission fluid I discovered a leak coming from the side of the transmission where the shift leveler connects to the tranny. It would leak a few drops of atf every morning, the mechanic quoted me $600 just to change the stupid little seal. I decided to try this product but I only poured less than half since the leak wasn't too bad and after 3 days of driving the leak complety stopped, thanks for saving me $$$ great product!! - Anyonio - Salinas, Ca
- Will Bar’s Leaks Transmission Stop Leak clog my filter?
No. Unlike our cooling system product, Bar’s Leaks Transmission Stop Leak has no particles to plug the leak, it works chemically to stop leaks in gaskets and seals.
- Will Bar’s Leaks work with all types of transmission fluid?
Yes, Bar’s Leaks is one of the only transmission stop leaks that is compatible with all petroleum-based transmission fluids including synthetics. Use in regular automatic or manual transmissions. Do not use in CVT transmissions.
- How does Bar’s Leaks Transmission Stop Leak work?
After time, transmission seals tend to dry out and shrink. Bar’s Leaks revitalizes these seals and makes them soft and pliable again.
- How much do I install?
Our 1420 (11 oz.) is designed for one bottle to be installed in a passenger car or light truck. For larger systems use one 1 bottle for every 10 quarts of fluid.
- If first application does not completely stop leak, may I add another bottle?
Yes, you can install a second application for hard to stop leaks. If your leak still persists after a second application, then mechanical attention may be required.
- If I install more than the required amount, will it work faster or better?
No, we have formulated our product to work best at the suggested dosage amount.
- How long does it take to start working?
Bar’s Leaks Transmission Stop Leak starts working the minute you install and start driving the vehicle. You will usually see results in about 200 miles or three (3) days of driving.
- Can Bar’s Leaks Transmission Stop Leak be used in a standard (manual) transmission?
Yes, you can use this product to help stop leaks in a manual transmission. Use approximately 2 ounces per quart of capacity.

“I want to thank you for making products that work. My transmission had a front pump seal that leaked out 4 quarts of fluid in about 300 feet. So I went to the auto store to get some fluid and see if I could find some stop leak. I wont put just anything in my car either. While looking around I found one that said Bar's I thought if anything will work this will. So I put it in and about 3.5 quarts of fluid and drove the car 30 some miles back home. I will replace the seal. But I did not need a wrecker. Thank you.”
