Abstract
A control system for an engine transmission provided with a coupling mechanism for engaging or disengaging coupling of the transmission. The control system has one or more valves movable between two positions for controlling engagement and disengagement of the coupling mechanism. The valves are connected to an automatic control unit which has an intermittent signal supply trigger for supplying an intermittent pulsed signal to the valves, thereby providing an intermittent movement of the valves between the two positions.
