The RE means Rear wheel Drive E means electronically controlled as opposed to RH which would indicate hydraulic control. Fourth gear (overdrive) is electronically controlled and hydraulically activated. A variety of sensor inputs are supplied to the PCM, which operates valve body solenoids. The overdrive control switch is located in the instrument panel. In the On position, automatic shifts into fourth gear overdrive will occur. In the Off position, the switch overrides the electronic control module, preventing a shift into fourth gear. So what if you turn off the overdrive manually will it exhibit the same condition?
