To make any auto trans shift faster... your gonna need a different "valve body" for the AT. Those guys in CA probably know what to do. Athough I am not sure IF they offer an package like that. The solenoids in the valve body need upgrading. Maybe even a different stall speed for the Tq converter too.
I think just about everyone here just runs the OE setup. Maybe they change teh trans fluid. But thats it. And there are a lot of guys here with autos and FOB's(full bolt on's),,,
