Re: PCM troubles
I'm sorry for the confusion, in the other thread I was just answering your questions about the PCM, and explaining why your transmission was acting like that, I didn't mean that the PCM was the problem.
As GMMerlin said, those codes indicate a loss of power to the tranny and it typically is the ignition switch that causes the loss of power.
With the switch on, check for voltage at fuse #11 (cluster). If no voltage or low voltage is present, then I would suspect the ignition switch (or faulty wiring for a remote starter if you have one)
If you have voltage there, try turning the switch on and off a few times to make sure that it remains constant.
If the voltage is present and stays constant, then inspect the wiring going to the transmission.
