ABSTRACT:
A control system for a transmission is disclosed. The control system includes a high clutch and a low clutch. When the high clutch is engaged, the torque transmission path through a V-belt type continuously variable transmission mechanism is established, while when the low clutch is engaged, the torque transmission path through a gearing mechanism is established. The same hydraulic fluid pressure as prevailing in a driver pulley cylinder chamber is admitted to the high clutch directly or via a suitable selector valve (a neutral valve).
