ABSTRACT:
A rugged and yet simple transmission gear selector apparatus includes a gear shift lever assembly having a lower lever portion mounted on a frame for pivotal movement about a first axis, an upper lever portion mounted on the lower lever portion for pivotal movement about a second axis normal the first axis, and with the upper level portion extending upwardly through a guide slot having a forward position and a reverse operating position therealong at the opposite sides of a longitudinal plane. An inhibitor mechanism is provided for blocking direct movement of the lever assembly between the positions and requiring a circuitous movement of the upper lever portion under an increased resistance in order to prevent the inadvertent selection of reverse speed by the vehicle operator.
