yes on neg cable extra clean. when I got the truck it had a broken ob2 connector[under dash] it has a replacement exhaust with straight thru, no muffle etc looks like 5 inch. with busted connector I suspect it had a programmer or some thing. Have checked codes only code is the one for too much boost got a junk yard connector and using Your wiring diagram replaced it. [thank you for posting that] That link and kit is probably how I will go.there is a wire from edge of pcm? next to air cleaner and it goes to a block ground, cleaned it I spent almost 8 hours on cleaning wires, and all connectors. Truck was used to travel the country picking up old/ antique motorcycles on a 20 ft trailer. Looks like good care but think trans, and a ps gearbox going out made the guy trade it to his friends motorcycle shop for a newer truck.

All ready did all grounds clamps any wire I could get too,even power contol modual wiring and grounds,have not done anything with trans wires from under truck ty for replys,again I keep seeing stuff about solenoids in trans pan

I have a 99 24v 2500 2wd Mostly happens when truck warmed up' It will drop out of OD and sometimes then drop to 2nd. I have dome all the cleaning up etc. I have fresh pink fluid no slipping just wont stay in od mostly. A funny thing is when it does this if you set the cruise it will take off running faster.Trans was rebuilt according to previous owner but don't know who. I have been told that the shifts are controlled by electric in trans. Have not but do intend to replace VSS, but got a feeling it is more then that. Thank you for any help [i do have a new alternator on way for lock/unlock problem.
