The invention relates to a method for setting the operating pressure of a transmission, in particular a motor vehicle shift transmission, the transmission having clutches, brakes, actuators, a hydrodynamic clutch, and/or a hydrodynamic converter, to which a medium that conducts the operating pressure can alternately be applied in order to vary the transmission ratio of the speed and/or the torque between a transmission input shaft and a transmission output shaft by opening and closing the clutches and/or brakes, by actuating the actuators, and/or by hydrodynamic power transmission using the hydrodynamic clutch and/or the hydrodynamic converter, the operating pressure being switchable between a constant nominal value and a constant decreased value 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. The invention is characterized in that a speed difference between the transmission input shaft and the transmission output shaft and/or between the input side and output side of at least one clutch, one brake, the hydrodynamic clutch, and/or the hydrodynamic converter is detected and compared to a predefined target difference, and the switching or reduction of the operating pressure is performed as a function of the result of the comparison. |
