External Controls - Overview: Overview

The shift by wire system uses push buttons called the GSM to command an actuator called the TRCM to change gear lever positions via a shift cable connected to the manual control lever located on the transmission.

The shift by wire system consists of:

• a GSM that uses push buttons to select the desired gear.
• a TRCM that changes the gear position via a shift cable.
• a mechanical selector lever cable that connects the TRCM to the transmission.

Whenever the TRCM or selector lever cable is replaced the selector lever cable adjustment procedure must be performed.
