None of the codes have anything to do with a transmission temp sensor... its saying the pcm is detecting high voltage on the power relay circuit for the transmission solenoids.. basically the cars is gonna be in limp mode.. you could be looking at a wiring problem or computer/tipm module problem... highly doubt the tranny needs rebuilt
