not holding overdrive???
hey guys if anyone can help me out this would be great.
I have a 07.5 cummins with the smarty jr. all deletes done and a 4 in tbe. I have had no problems with the tranny and have had in inspected by a transmission guy here in town and there is no problem with the tranny itself. and have had it into a dodge dealership thinking it was the ecm and even with that we had no luck in solving this problem. the ecm and the tranny seem to be right where they need to be.
the problem is the truck staying in overdrive while loaded or without hauling. it is possible to get the truck into OD for a brief period of time until a hill of any size or grade comes up and an automatic drop in gear while sending the rpms flying up. from a stop the truck performs awesome with grabbing gears and putting the power to the ground. just having problems when at higher speeds and trying to hold it in OD. automatic trans of course.
if anyone has had this happen or knows anything about why this would be happening a little info would be great.
thanks
