Zusammenfassung:A device for the hydraulic control of an automatic transmission, especially a continuously variable automatic transmission. The control system comprises a forward/reverse drive unit, which is controlled by way of at least a first and a second shifting component. The shifting components are in turn controlled via at least two valves, which are pressurized by way of a pressurized medium pump. A gear selector device selection is made among at least a forward gear (D), a neutral gear (N) and a reverse gear (R), wherein the selector device possesses a non-mechanical connection to the transmission control system.
