Hello- I just read the new TDR and saw a question about the transmission not shifting into or out of OD. My problem is a little different. I have a 1998 3500, 4 WD. When I start the truck up, and drive into town (about 13 miles of staright driving, no stops) the truck will shift into OD when the tramsmission is cold. I have all gauges installed, so my transmission temp is monitored. At the first stop sign, when I accelerate, the truck will not shift into OD at all. I have checked the fluid level, its good. The fluid does not smell burnt. The OD button is and has been intermittent. When I read my MX manual, it said the transmission will not shift out of OD until the transmission temp reaches 148 F. I then try the OD button and it seems to be intermittent as compared to when I bought the truck. Could it be that simple? What else can I check?
Thanks.
Kenny
