Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Mostly, we see that happen with vehicles that are being driven in overdrive when either towing or carrying heavy loads - fluid heats up and OD clutches get burnt. Are you detecting any slippage or abnormal downshifting?
If there is no slippage, then the only other possibility would be most likely a bad connection at the 23-way connector on the valve body creating false signals that the PCM is interpreting as faults.
I know. sometimes these things drive us crazy... Just look at it this way; the connector is about the only thing left that you haven't either replaced or repaired that can cause the code.
I surely hope that's it and that you can fix it easily enough. Please let me know what you find.
Keeping my fingers crossed :-)
Sorry, but I'm all out of ideas. I'll opt out and re-open this up so other experts can chime in.
