ABSTRACT:
A method and apparatus for electrically activating range shift apparatus in transmissions of trucks or the like wherein such activation is customarily accomplished by actuation of valves on air lines from the shift apparatus knob to the proximity of the transmission, such air lines, or the like, are directed along a shift bar from the transmission area up to the knob of the shift bar and then along the shift bar to the point of actuating shift changes in the transmission. In the present case electrical switch apparatus in the knob of the shift bar is provided which electrically actuates a low voltage solenoid valve arrangement which controls the transmission's air actuated shifting means without the need of relays, and the like.
