Bar's Leaks1420 Transmission Stop Leak - 11 oz. , Grey

It a chemical stop leak a last resort use only before pulling out the transmission will see 50/50 chance it does something maybe slow down the transmission leak at the main seal

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 againIt stopped leaking after I added a second bottle... After a week checked transmission fluid level... And level read FULL... Hasn't leaked since

This completely stopped a small leak of transmission fluid.

Appears to be working fine.

did not work for me

Bar's concentrate transmission stop leak is vary effective on pneumatic BB and pellet guns two or three drops on the pump seal and you should notice the difference on the chronograph. As Tom Gaylord claimed.

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 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.
