I've asked this (as I'm sure others have) but I'm wondering how the various Patterns x, y, z work in reference to shift scheduling pattern A and B (and normal of course, all work together (if they even do) based on trac lock off vs stabl atrak off (or on).
Is there some way that the trans tune can be made to recognize a different shift patter for one or both of these settings being on or off?
Even under Shift General you have pattern type A and B which have choices like tow or performance.
An example is my 2000 Regal GS, if you pushed the "Performance Shift" button on the shifter it used a whole different tune spec.
So, short question, how does our TCC and Stl atrak buttons turned off affect our tune, or can it?
