Shift Indicator - A/T: Description and Operation

SHIFT INDICATOR

The instrument panel cluster (IPC) illuminates the shift indicator when the engine control module (ECM)/powertrain control module (PCM) determines that the vehicle should be shifted to the next higher gear. The IPC receives a class 2 message from the ECM/PCM requesting illumination.
