OK....today I went on my second road trip after the OD light blinked that one time. Both trips were a couple hundred miles and no problems at all. The tranny never shifted funny or anything. The light blinked that one time and one time only. I noticed it blinking and it seemed to run OK so I drove to the campground maybe 50 miles and it seemed alright. The dealer said the TQ slip code came up. Maybe the tranny is still good.??????? I will wait till I pull my trailer back up to Clermont again and it may start blinking again under load. If not, what do you think.? The truck is maxed out with a 20,000 pound trailer so I could understand it if it needs replaced.
