2000 buick regal GS performance shift button not working
I push the performance shift button the light in dash comes on but nothing
changes. how do I fix what ever is wrong ... Module?
Not sure on the Buick, but the performance shift button usually allows the transmission to hold the gear longer when you accelerate quickly. So your not noticing the extra few seconds it stays in the lower gears?
this is my 2nd GS and that is correct it does not hold the gear, therefore the performance shift is not active even when the light comes on from me pushing the button
so its not the button its what ever the button activates or a broke wire ... But where and what makes the tranny hold the gear longer
