What’s your battery voltage, and your alternator voltage? Transmission ECU is especially picky about the voltage it gets. You have quite a few faults that could possibly be caused by slightly low voltage. (This is the first thing I would check).

 

Thanks Trek. Voltage for battery is 12.5 and alternator is 13.9

 

Is that 12.5 at the bat with the engine off or engine running? And, of course, 13.9 at alt is with the engine running?

 

This was while the engine was running.

 

OK, well that's a problem. With the engine running, measuring across the battery should give you the same voltage as the alternator output. What is the bat voltage with the engine off? It is important to be deliberate about where you are taking voltage measurements. If you are in the engine compartment, you should make your measurements from the battery neg term to whatever you are measuring. As you dig deeper into a question, you might well want to measure from a different reference point, but start with your negative voltmeter lead on the negative terminal of the battery. Measure your engine off battery voltage; then start and measure bat again; and measure your alternator voltage with the same battery gnd terminal reference.

 

Thanks for the information! I will do that. I also cleaned the codes- got a bank 1 fail - ordered a new O2 upstream sensor. It then gave a cylinder 3 misfire after I drone it for a min.
