I know that the earlier 90's Z's have the problem with the grinding gears in 4th and 5th. I have that problem although it is not that bad (doesn't grind when upshifting unless im racing/accelerating at a high rate). Only grinds if i try to go from 5th to 4th above about 42mph.

Are all the transmissions from the 90-96 Z32's compatable on all the years?

So for example, i could get a 96 tranny on my 91 (with little/no modifications to install) to elimiate this problem?

 

yes.........

 

JUST MAKING SURE!

 

NO! you cant intermix between NA and TT missions without modification However, same type missions work on any year Z32 as napoleanzking says.
