Have Transmission Questions? Ask a Mechanic for Answers ASAP
Hello: what you are experencing is an open thermostat or a bad coolant sensor(for the transmission, located at the rear of engine), See these were designed to keep the transmissions from going into over-drive untill the computer sees normal operating temps, (to keep the over drive clutches from failing,) When you first start the car it should only take about 5to 10 mins, for it to reach normal temp on your gauge, If it is taking loner then that, Replace the thermostat!, If this is reading normal, and still have no over-drive then replace the transmission coolant sensor at rear of engine! Thanks, ***** ***** Very Merry Christmas!
Please let me know if I can be of any other help with this issue!
