Winter Mode Switch

In the Winter mode, the TCM changes the shift solenoid states in order to start the transmission in 3rd gear. By starting to move the vehicle with the transmission in 3rd gear, less torque is created, thereby reducing tire slippage on ice and snow. When the driver selects the Winter mode, the TCM overrides the selection of the Economy or the Sport modes. The TCM only enters the Winter mode when the following conditions are met:
- The selector lever is in the Drive Range (D).
- The vehicle speed is less than 10 km/h (6 mph).
- The transmission fluid temperature is less than 130° C (266° F).
- The wide open throttle (WOT) switch is off and throttle opening is less than 7 percent.

The Winter mode cancels if any of the following conditions are met:
- The Winter mode button is depressed.
- The selector lever is moved to the Park position or the lower drive ranges (the TCM will remain in Winter mode in Neutral and Reverse).
- The ignition key is off.
- Transmission fluid temperature is greater than 130° C (266° F).
- The wide open throttle (WOT) switch is activated.

When the Winter mode cancels due to one of these conditions, the TCM returns to operating in Economy mode, regardless of the operating mode before selecting Winter mode.
