Transmission Control Switch (TCS)

The transmission control switch (TCS) is a momentary contact switch located on the floor shifter knob. Pushing the transmission control switch (TCS) will either disengage or engage the overdrive function of the transmission. If the overdrive (D) is disengaged, the message O/D OFF will illuminate on the instrument panel.
