The TPS tells the PCM how much pressure to use in the transmission. While at idle very low pressure and low heat generated.

Erratic shifting I would understand, but I don't get not going into gear.
If it is not an E4OD then his problem is inside the transmission.
After rethinking all of this you are more than likely right and it is not the TPS.
It would be one of the items on the list below if it is an E4OD.
Delayed engagement -- neutral to drive and neutral to reverse.

well i dont know about other guys tranny but mine is the e4od. Your list is pretty scary, so i think il try the sensors u mentioned first, seeing how there is a pick you part here il grab a few of each sensors and see if the problem persists. I relly hope it doesnt require more than changing the fluid and filter. If it does than might as well replace the whole thing.
