So i got a 93 blazer sport with a 350 and an auto trans that wants to slip in the 3rd to 4th range. SO i also have a 91 chevy sport 4x4 with a goood trans and transfer that i want to install into my lifted blazer. i have done this many times with the 92 and older style but not on one with a 4l60e in it. I know about the clutch switch and so forth....... but what about the other wiring going to the trans. do i need to jumper bypass or just leave it hanging . or set it to shift selector in park and leave it be. just currious to what problems the computer will throw out and how to trick it to think everything is fine
