It sounds like two different issues. First, as far as the engine temp, make sure the coolant is full and clean. Also, has the thermostat ever been replaced?
As far as the transmission, if it isn't shifting soon enough, it could be over reving the engine causing it to overheat.
Now the trans, there are a few things. It could be the trans countrol module (TCM), a bad shift solenoid, or it may be time for an overhaul. Can you describe what it is doing?
