I have a 1998 Chevy Cavalier, and when it gets hot out the check engine light comes on and while driving in town my temp gauge drops from normal to cold, and when it does that my trans shifts hard. But when the light come on and im driving on the highway nothing esle happen it drives fine. Any sugestions?

Replying to: morris2008 (Apr 12, 2008 9:40 am) If you have the Trac Off light coming on at random times and the transmission jumping into low gear here is the answer: Replace the TPS (Throttle Position Sensor). $30 to $40 if you do it yourself or $70 to $95 if you have a service station do it. Of course you can pay a dealer to do it but they will charge you hundreds of dollars, (just my opinion). This will fix all of your problems related to the TRAC OFF light and transmission shifting into low gear.
