I have a 2004 Dakota 2WD with V6, Automatic Trans and 13K on the odometer.
The transmission usually starts off normal, going through all the gears but some miles down the road the tach starts to drift higher as the engine speeds up. Example: On cruise at 50 mph, on level ground, the tach should show 1400 rpm. After a few miles, however, it will, for no apparent reason, start to drift higher, up to 2000 rpm. If I shift the gear lever into 2 and back to 3 the tack will quickly come back down to 1400 and stay there for a few miles before drifting up again.
The dealer said there was a diagnostic code indicating a problem with the transmission but they didn't believe it so they attempted to correct the problem by re-booting the computer. That didn't solve the problem so I took it back. Next time they told me that this behavior is normal and there is nothing wrong with the transmission.
I can't accept this diagnosis as I know it is not normal. Can you tell me what the cause is or how I can go about getting it resolved?
I will be pleased to make a donation if I get a meaningful solution to the problem
