Leaking transfer case

I towed my 4x4 Grand Cherokee about 500 miles with the steering wheel locked before I realized what I'd done! Oh snap! The transfer case ALMOST separated from the differential but miraculously I was able to save it just by gently shoving it back in and forcing the gears to hit. From that point on the tranny started to slip. It would go from 1st gear straight into a hard 3rd and I thought I'd toasted the tranny for sure. I just added my 2nd bottle of Bars Leaks and while it's not completely factory-grade repaired it has gotten me another solid 600 miles that I didn't expect and I'm not quitting til she's up on blocks! I live by this product.

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 won’t 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.

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!!

About one year ago, I purchased a bottle of Bar's Leaks power steering stop leak concentrate and it solved my power steering leak problem.

About two months ago, I was experienced a loss of prime on my automatic transmission when I stopped at traffic lights (Buick Terraza). I decided it was either internal leaks or scored pump. I put in a bottle of your Bar's Leaks transmission stop leak concentrate and my problems have disappeared. Apparently some internal seals were softened up enough to again do their job.. Your technology is good for more than power steering! You probably already know this but I just wanted to thank you!
