It's too bad because it has good ratings and seems to work ...
Frank B.•September 19, 2017
Did not work on the transfer case on my Toyota 4Runner.
Even though it advertises that it works on gearboxes.
It's too bad because it has good ratings and seems to work for a lot of other people.
It didn't even slow my leak down.
I would not recommend it for a transfer case.

DO NOT USE THIS!!!

Avoid this product at all cost. I had a small drip under my car and after using this the car is undrivable. ATF pours out of the tranny as fast as I can pour it in. It totally ruined the seals. I will now have the luxury of spending thousands of dollars to have my transmission rebuilt.

Okay But Not Perfect
DANIEL L DALY•April 3, 2017
I added this to my Dodge Durango and it lasted about three days before I had to add more transmission fluid. It lasted longer than the other sealers I used but it is not perfect.

I put some of this in my 99 GMC 3500. It was leaking when I bought it. They guy I bought it from had replaced the seal, but thought that maybe it didn't seat properly. I wasn't sure if this would help, but thought it was worth a shot. Cheaper then having to pull everything off and replace the seal. For now at least. It seems to have helped. Doesn't seem to leak as much as it did before. There is still a little leak, but that's kind of expected for what I thought was really going on.
