Component Description

WARNING: This page is about a different variant/trim than selected.

When changing gear position, the driver selects PRND or M by rotating a GSM dial. The GSM senses the dial position and sends a request to the TCM. The TCM receives the input from the GSM, combines in vehicle conditions to determine commanded transmission range then sends a command to the solenoids in the transmission. The transmission acts on the command from the TCM by moving the transmission to the commanded position via internal solenoids. The TCM reads the Transmission Range (TR) sensor and confirms the correct position has been achieved. The TCM then sends a message to the GSM and the IPC to display the current transmission range.

GSM

Each GSM rotary dial has Hall-effect sensors that are used as inputs that the dial has been rotated. When park is selected above 8 km/h (5 mph), neutral is provided along with a message in the IPC.
