Component Description: Notes

When the driver needs to change gear position the driver selects PRND or M by rotating a GSM dial. The GSM senses the dial position and sends a request over the Subnet Network, and the High Speed Controller Area Network 2 (HS2-CAN) through the GWM over the High Speed Controller Area Network 1 (HS1-CAN) to the TCM. The TCM receives the input from the GSM, combines in vehicle conditions and moves the transmission to the commanded position. The TCM reads the transmission range sensor (TRS) and confirms the correct position has been achieved.

There is a redundant Transmission Controller Area Network (TRANS-CAN) that allows the GSM to communicate directly with the TCM in the event of a malfunction in the HS1-CAN, the HS2-CAN or the GWM.
