Ford Fusion: Automatic Transmission External Controls - 6-Speed Automatic Transmission – 6F35 / External Controls - Overview. Description and Operation
Overview
The shift by wire system uses a rotary dial mounted on top of 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 a rotary dial 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.
