could someone please tell me what the button is on the gear shift on a 97 cadillac cetera. and will it hurt to drive with it on? i have no manual so i don't know. another question i just got my trannsmision filter and fluids changed and when i hit 60 mph the quotation light comes on, and it came on before i had it done,can you tell me why. last time i put something on here about it a man said it was a range switch. anyone know where it is, so i can get it replaced. thank you.
