Transmission Control Switch (TCS)

The transmission control switch (TCS) is a momentary contact switch that is located on the transmission range selector lever. The transmission control indicator lamp (TCIL) is located in the instrument cluster. Pushing the TCS will either disengage or engage the overdrive function of the transmission. When overdrive is disengaged, the TCIL will illuminate the word OFF. Each time the ignition switch is placed in the RUN position, the transmission will automatically provide overdrive operation regardless of TCS position the last time the vehicle was running.
