Does anyone know what the correct shift speeds for a 2002Dodge diesel 2 wheel drive truck with 3.55 rear axle and the 47RE transmission should be? A few months ago the dealer rebuilt the trans (under warranty) and fiddled with the shift speeds. It shift 1st to 2nd at around 17 mph, 2nd to 3rd at 25 and into over drive after 40mph. I can coax it into OD a little early on flat road with constant speed by momentarily lifting off the accelerator and the pressing back on the accelerator again. It will usually shift into OD but any increase in throttle pressure will cause it to drop back into 3rd.
