The overdrive won't engage so I'm running near 3000 RPM when I reach 60 MPH. I read that I need to replace the Overdrive sensor or to ground the sensor. Has anyone faced this problem? How did you fix it? <img src="/forums/images/graemlins/scared.gif" alt="" />


I had an 89 that did this same thing, wouldn't shift into overdrive on the freeway. Turned out to just need a new thermostat. The temperature of the engine controlled when the vehicle would go into the highest gear. Good Luck
