i've been pretty harsh on my truck. 84 22r with a G52 and the only real thing that's really happened is that now my 3rd gear will grind a bit when i try to shift quick with high RPMs. and i haven't had my tranny rebuilt or anything but a new clutches and pressure plates and bearings. my truck has got 195,400 miles. not sure what to tell you. can you remember the name of the place.
