There is some stuff you can play with but since you have a 700r4 tranny thats not electronic the shift points have to be done by a shift kit.


Welcome to the site, I also have a 87 blazer. Mines 2.8, auto, 4x4.

Its been good all but it has ate the drive gear in the transfer case and its a part with GM has decided to quit making. Know anybody with a spare np207 that was in a truck with 3.73-1 gears they wanna part out, lol.
