Automatic Transmission Multifunction Stalk Switch

wv dm 7.02.005

Some vehicles are equipped with a multifunction stalk switch shown in Fig. and see Fig.. This control can be used to request direction, neutral, low, manual shifts, change driving mode, preselect lower ranges, and set engine brake levels. Forward shifts can be made either automatically or by using manual mode. For an overview of control functionality, refer to Table..

Note: See Table for a description of control functionality.

  • Rotate for drive (D), neutral (N), or reverse (R).

  • Short press for automatic mode when in manual mode.

  • Long press to switch between economy or performance mode.

  • Pull for upshift (+) request.

  • Push for downshift (-) request.

    Note: On some vehicles, the engine brake only has off and high intensity options.

    The transmission has electronic shift controls that can be programmed to allow the use of different numbers of geared speeds. For instance, the transmission can be programmed to operate as a 4-speed, 5-speed, or 6-speed unit in the ‘primary’ shift mode. If needed, a ‘secondary’ shift mode can be programmed to provide another shift configuration to optimize vehicle use under different operating conditions. To activate a secondary shift mode, or other special functions programmed into the electronic control unit (ECU), briefly depress the mode switch on the multifunction stalk switch control. See Fig., Ref. B and Ref. C.
