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

Works
This completely stopped a small leak of transmission fluid.

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.

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.

Know what your using this for.
It may sound very simple, but this product is not a Fix all!! If you have a seal that maybe is slightly leaking, a dime or nickel size puddle under your vehicle overnight, this product works really well. If you have an 8 inch puddle under your vehicle, don’t use this product. Do it correctly and replace the seal. You can’t expect miracles for five bucks! I have used Bars products in the past. . If you keep it within the intended limits, it will do a great job for you.

Worked as advertised on a Ford manual transmission
This worked on a 5 speed manual transmission in a 2001 Mazda B3000 (Ford Ranger with Mazda lipstick) with 125,000 miles and a seeping front transmission seal. Trans was drained, 6 oz of stop leak was put in, then topped off with Mercon ATF the service manual calls for. After driving it 200 miles no noticeable leak was found. While this is like putting a band-aid on a broken arm, it is a good temporary fix for minor seepage or drips. Larger gasket or seal leaks may require actual repair; YMMV with this product but it worked great for my needs.

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.
