I have found that my performance shift light has come on, at times, by itself. I'm not sure if i hit the button by accident, or if it is a problem with some other gp's. just trying to find out what the heck it could be. i notice that it comes on after i agressively hit the gas, and my tranny seems to be a little sloppy. is there any suggestions on the light and maybe sprucing up my tranny (without removing and rebuilding with high performance parts). cash flow is tight, as i'm sure alot of you know.
