Sorry I have a 1998 Pontiac Grand Prix GTP and the problem is my "Perfect Shift" light wont illuminate. I believe the Perfect Shift is when the button on the shift lever is depressed. It is in Perfomance Shift Mode when the button is released it might be reversed. I cant tell my wont illuminate at all. The guy I purchased the car from did do some Mods to the car. Carbon Fiber Hood, Headers, and the vehicle was was lowered and Performance Struts installed. And now I cant contact him to ask if he disconnected the button.
