The apparatus comprises a selection knob rotatable between angular positions for selecting an operating mode P, R, N, D of the transmission controller; and a knob-rotation-control mechanism configured to engage and hold the knob in the angular positions; and to move the knob automatically back to a desired (park) position when particular vehicle conditions are met. In first embodiment, a reversible motor operably coupled with the knob-rotation-control mechanism is configured to slidingly move the knob-rotation-control mechanism between a locked position that prevents knob rotation, an unlocked position that allows knob rotation and gear selection, and a second unlocked position (with feel positioner released) for automatic return to the gear position when predetermined vehicle conditions are met. In another embodiment, a reversible motor and a linear actuator provide coordinated operation to accomplish a similar result as the first embodiment. |
