Are you referring to the gage reading hot? Obviously I'm not there so forgive the thoughts here... Is it actually hot i.e. do you smell anything, does it operate ok, etc? Is the fluid burnt i.e. dark, smell funny, etc? If it is operating OK then it could be the gage. If it is a message from the message pane then it could be other items i.e. sensor, wiring, etc... I'd be careful here money and safety-wise... Good luck

Ok checked the fluid and that seemed fine but it definitely smelt burnt. It was a pinkish color though. Drive around the block this morning, shifts fine until you hit 30mph then revs up and doesn't want to shift? !!
Transmission shop not open till Monday. Any suggestions on what it could be?
Thanks for your replys.
