Hello,
I have a 2002 Dodge Dually 4x4 Cummins, automatic transmission; boost, tranny temp and exhaust temp gauges. I have a K&N air filter (clean), 4" smooth bend exhaust and one of those computer override gizmos on it: I think it is an EZ-Edge. I am the original owner.
I drive it mostly empty, but occasionally drag a 10,000 pound or so boat.
Last weekend, after I dumped the boat into the water at the boat ramp, I could hardly pull the trailer up the ramp. I had the thing floored in 4x4 high mode, the turbo boost was up to 20 PSI, but it would hardly move. After I put it into 4x4 low, then it pulled it up just fine, although very slowly. The ramp is in decent shape and the trailer was not hung up on anything.
Then, the thing would rev way too high before shifting into second and drive while pulling the trailer to the parking area.
I took the boat out and came back about 6 hours or so later and the truck dragged the boat up the ramp just fine. Then, on the way home, which is about a 50 mile ride, it took forever to shift when starting out from a dead stop when I was about 1/2 way home. When I got home, I put the thing in park and just let it idle for a bit. The tranny temp gauge was up about 100 degrees more then normal; where normally it will cool right down when idling. I left the boat out on the yard so I could wash it the next day. The engine temp was in the low end of the normal range and the exhaust temp had settled down to about 350 degrees after idling for a bit, but was just about 1,000 when dragging the boat.
The next morning (we are talking Monday now), I wash the boat and then park the boat in the barn. The truck drags it around the yard just fine and seems to shift just fine.
Then, today, while driving to work (empty), it shifted just fine too. The tranny temp gauge hardly registers which is 'normal'.
The truck has about 85,000 on it, and this is the first time I noticed this problem.
What's the consensus: Tranny problem or something else?
Thanks for any tips.
