I still need to have the engine scanned to have the cam retard set. I have an appointment Monday with my local GM dealership. But now after the same plastic gaskets were installed rather than the new ones that are metal . The trust is gone.
Has anyone here ever had a knock from the tranny? Not the normal start up knock. But a real knocking sounds like tapping with a ball peen hammer at different intervals.
Thanks in advance.
