i have heard that this stuff is really good. But i just wanted to get some opinons on it. Cause i have heard of people putting this in with like a bad 2nd gear synchro and it helping out a lot. IS this true

just give some of your opinons and if u have ever used it or not?

one more ques? is it and additive that was what im not sure on also

 

I know that Redline tranny fluid can cure some synchro problems temporarily, so maybe it does. Anyone try the GM stuff?
