Transmission Control Switch

Transmission Control Switch (TCS) may also be referred to as overdrive (O/D) cancel switch. The TCS signals the PCM with keypower whenever the TCS is pressed. TCS position is controlled by vehicle operator. If overdrive is disengaged, O/D OFF indicator located on instrument panel, or Transmission Control Indicator Light (TCIL) located on shift lever, will illuminate.
