ABSTRACT:
A vehicular steering and transmission shifting control mechanism includes a transversally rockable control handle and a steering actuator element connected at the bottom thereof to selectively depress either a left or right actuating plunger of a hydraulic pilot valve assembly for effecting steering. The control handle is contoured to be easily grasped and to position an electrical switch actuating element for comfortable movement by an operator's thumb to change the speed of a multi-speed transmission through an associated electronic transmission control system. A three-way electrical switch actuating element at the front of the control handle is adapted to be rocked to select one of forward, neutral, and reverse modes of the transmission.
