i am going to put in a high stall converter in my car and was wondering if the car needs to be tuned. i am probly getting a TCI 3500 and a trans go shift kit. is there a wright up on how to pull the tranny to put conv. in? how hard is the shift kit to install? what cooler should i get for the car? and will i need a tune for all this or will i be fine without one?
