1990 SPG transmission replacement questions..... Posted by vsfoxe [Email] (#1025) [Profile/Gallery] (more from vsfoxe) on Sat, 7 Sep 2019 12:54:31 Members do not see ads below this line. - Help Keep This Site Online - Signup |
My '90 SPG seems to want a replacement - 5th gear synchronizer is bad. It has a GM55704 transmission ('90 Turbo transmission). On floor in garage I have a GM45712 ('89 NA transmission). Are there differences in the 2 transmissions? Will parts interchange between the two?

I noticed yesterday that the front motor mount is bad. The engine lifts up under power with brakes on. I will change that front mount before I go any further. Is hydraulic mount more smooth than the solid mount?
Opinions or suggestions, please? Vern
