Transmission Control Switch (TCS)

The Transmission Control Switch (TCS) is a momentary contact switch located on the selector lever knob. Pushing the TCS will either disengage or engage the overdrive function of the transmission. If OVERDRIVE is disengaged, the message Overdrive (O/D) OFF will illuminate on the Instrument Cluster (IC).
