Abstract
A remote controller for the transmission of a material handling vehicle having a lower chassis on which is mounted a truck cab, an engine and the transmission and which pivotally supports an upper structure including an upper cab and a material handling implement is provided. A three-way rocker switch is mounted on a joystick in the upper cab and is connected via a single control wire through a single slip ring to the main shift controller. The rocker switch is normally biased with a reference voltage which, when the switch is actuated to its other positions is either increased or grounded. First and second comparators in the main shift controller monitor the voltage in the control wire and cause a counter to increase or decrease the number stored in its memory on the basis of increases or decreases in the control wire voltage. The main shift controller then outputs a signal to the shift solenoids of the transmission based on the number stored in the counter.
