1991 GMC Sonoma QuestionsWhy is transmission not shifting properly after I replaced starter? (1 answer)
Replaced the starter in my truck after it wouldn't start, but now the transmission is not shifting properly. When I started the truck, it was automatically in reverse, but not sure if shifter was in park or neutral. Gears appear to be off by one position?
When you turn off the wipers they stay in an up position how do I get them to stay on a down position
and I don't know why i just had my heads and my throttle body redone it was blowing clouds of white smoke every time I turned it on or let it sit while running now it does it only when it's cold or low on water.... need some ones opinion !
