Special Shift Programs

These specific condition shift maps are available to enhance the operation of the vehicle under specific driving conditions and are listed below in order of priority/title and operating condition.

1. Traction: When traction intervention is active.
2. Hot mode: Extreme engine/transmission temperatures.
3. Gradient: Under specific speeds and loads.
4. Cruise: During cruise control.
5. Manual: Shift map when the LH side of the "J-gate" is used.

Three specific condition shift maps have a higher priority than the two base shift maps and will intervene when appropriate conditions prevail for traction, gradient or cruise.

When traction control (engine or brake system derived) is operational the TCM will implement the traction map to maximize control of wheel slip.

The gradient maps are intended to enhance vehicle driveability when towing or climbing a gradient. The TCM will implement the maps when increased driving resistance is detected and enhanced driveability, cooling and increased performance is appropriate.

The cruise map is intended to minimize unwanted gearshifts and "hunting" and is activated when cruising near to the set speed, or resuming.
