ABSTRACT:
An apparatus for indicating the position of a gearshift mechanism of a transmission which includes a plurality of forward-speed shift bars contained in and movable within a transmission housing; a number of microswitches are mounted in the housing for selective engagement by the shift bars. The microswitches feed a coding device which generates unique binary codes depending upon the microswitch or switches engaged by the shift bars when the latter are moved into position by a gearshift selector lever, for engaging one of a number of gears of the multiple gear transmission. The binary coded signals are decoded in a decoder/driver which in turn is connected to a digital display device for numerically displaying the selected gear.
