Anyone know the final drive ratio for 3x4 trans? .77 I think? How about a 6 speed and auto? thanks
You mean the 4+3?
Mine is 0.68 in it's final gear. There is another version that is 0.60. I believe the 0.60 version was used on non-Z51 cars. The only differential option was a 3.07 gear with all 4+3 trannies.
