i have a 2006 2500 with the 5.9l diesel. to shift from 1st to 2nd i have to let off the accelerator then slowly press it to get into 2nd gear. on flat ground the problem is hardly noticeable, on hills though it seems more present. im wondering if anyone can give me any type of insight, its been doing this for a year, w/ no sign of a real transmission problem. im wondering if maybe the shift points got changed when the superchip was added (im not the 1st owner, and didnt install the programmer). also, the truck only has 96k on it. also, any sites that might have better info on this?
