Your trans is controlled by the computer. A tuner will allow you to set shift pressure and shift points. When you buy a tune from a professional tuner it includes mods to the shift points and pressures.
No shift kits required.

+1. the old shift kits your thinking of with the springs and balls, and the adjustable vacuum shift mudulators for the old day auto trans, is a thing of the past and been replaced with electronics. now you just buy a tuner. tci has converters and shifters for the auto.
