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 selector lever 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 selector lever cable.
• a mechanical selector lever cable that connects the TRCM to the transmission manual control lever.

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