Two applications worked
This product really works... Took about a week for all the fluid to leak out of transmission... Added 1 bottle and a week later the fluid leaked out again It stopped leaking after I added a second bottle... After a week checked transmission fluid level... And level read FULL... Hasn't leaked since

It did not help a minor seal leak on manual transmission
I had shifter a shaft seal leaking on a four speed. It did not cure it. It did not help it.

Worked well.

Works, for now anyways
It's not a permanent fix, but it slowed the leak down to hardly anything, depending on what you need. My truck is old with high mileage, so not putting more money into her, but this stop gap is worth a try.

Didn't work
Didn't work at all. I read the reviews and followed the instructions and it leaked out as fast as before I put it in.

i bought this product, not for anything to do with automobiles, but for caring for, and repairing the seals in my Air rifles and Air pistols. Bar's Leaks Transmission Stop Leak is a miracle product for restoring your various inner seals that make an Airgun work!

Had a minor leak. One application and good to go. Not a spot from my transmission for over two weeks.

Slowed down the leak but didn't stop it. Mechanical problems and requires repair

Put this stuff in a leaky transmission. Did not want to junk the car yet but it’s old to fix it. It slowed the leak for now. Smells pretty poisonous.
