There is provided a method for setting an operating pressure of a transmission, the transmission having at least one of clutches, brakes, actuators, a hydrodynamic clutch, and a hydrodynamic converter, to which a medium conducting the operating pressure can selectively be applied, in order to vary a transmission ratio of at least one of a speed and a torque between a transmission input shaft and a transmission output shaft by opening and closing at least one of the clutches and the brakes, by actuating the actuators, and/or by a hydrodynamic power transmission using at least one of the hydrodynamic clutch and the hydrodynamic converter, wherein the operating pressure being switchable between a constant nominal value and a constant decreased value that is smaller in relation thereto, or the operating pressure being reducible in three or more steps or continuously from a nominal value to a decreased value.
