Mine is the later 04. The icp is on the p/s valve cover. I'm taking it to a shop friday if it doesn't get any better. I will find the link to the trans and vgt re-learn and try to post it up tomorrow if I can figure out how to. Thanks again. The truck runs great if you get on it hard. But idles rough. If you hold the brake when stopped it smooths out and still shifts hard/slips? When easing on the gas but shifts good when on the gas hard.
