Ok I got a 16v coming and I am undecied on the trans the one i can get readily is a 4 spd Auto (which means I need the computer) since it would basically be 100% kick I would not have to do anything to the wiring harness (input??) or should I find the 3spd auto and convert the harness and be done with it I was told i need the kick computer in order for the 4spd auto to work properly,,
