Abstract
A transmission controller is provided for use with a vehicle having a transmission including a plurality of gears. The transmission controller comprises an automatic gear selection control for developing control signals for controlling automatic selection of one of the plurality of gears. A throttle position sensor produces a throttle position signal corresponding to the position of a manually operated throttle of the vehicle, and an engine sensor produces rpm signals corresponding to the engine speed of an engine of the vehicle. The automatic gear selection control includes a control signal producing circuit responsive to the throttle position signals and to the rpm signals for producing signals for controlling the selection of a lower gear in the event the sensed engine speed comprises less than a preselected percentage of a predetermined no-load engine speed at the sensed throttle position.
