The Transmission Control Switch (TCS):

• is located on the end of the selector lever.
  • The TCS  is not removable from the selector lever. Install a new selector lever if a new TCS  is required.
• is a momentary contact switch.
• commands the PCM to disengage or engage the Overdrive (O/D) function of the transmission.
  • When O/D  is disengaged, the message O/D  OFF will illuminate on the Instrument Cluster (IC).
