Re: Transmission issues?
Regarding the transmission, eventhough a new problem can allways occur, i still would suspect some problem with the governor circuit or sensor circuit. Maybe a not well connected connector?
Regarding the O2 sensor, now that it is disconnected, the bank 1 will now run in open loop, which will increase the fuel consumption. Eventhough the sensor can be bad, it can also be that the wiring has melted due to contact with a hot exhaust part. The heater circuit can then feed the sensor circuit and a too high voltage will be sensed by the PCM.
The P0113 code didnīt show up before? It is a good thing when new codes pop up, to reset them and see if they come back again.
I didnīt know that the O2 and the governor sensor share the same ground. I would check the O2 sensor wiring first, because a melted isolation could cause a voltage input back to the governor sensor circuit and cause strange problems.
