I am getting a code P0712 on my 2002 Ford F150 5.4 automatic 4x4........ Dealer said transmission temperature sensor was
bad, installed new sensor and cleared codes, pulled trailer and OD light started flashing and code is back.Also constantly shifth in and out of OD when driving a steady speed between 30 mph and 50 and is worse when cold.Any suggestionswould be greatly appreciated. Also voltage readings when engine is warn are 0 volts to 1.7 if you rev up the motor. Temp sensor displays 380 degrees all the time.
