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

Did i really use this stuff?? Yeah
Cant believe I used this stuff as i always repair correctly but this is a 200K mile engine and to replace the head gaskets is a huge job and not worth it so this was a very last resort effort before I junked the car. My coolant was getting that rust looking crud in it and I did a test to confirm there were combustion gases getting in it. Used this for several driving cycles and after about a week, no more over pressuring! Did another gas test and its clean! This was a year ago and Im still driving it. I do not take it on long road trips but it does errands and short highway drives everyday.

Great product
I used this in my manual transmission and within 2 hours the leak stopped. By the time I did drive the mileage recommended, the leak had been long gone, great price.

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.

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.

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

Supplier delivered on time
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.

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