A clutch is operated by an actuating pressure pressure during an engaging process of the clutch. The actuating pressure is controlled over time such that predetermined characteristics for an engagement of said clutch are approximated by starting a process for changing a rotational speed of an output shaft of the torque converter for an adaptation of the rotational speed to an actual velocity of the vehicle during engagement of the clutch. An ideal signal for the rotational speed is determined which corresponds to an estimate for an engagement of the clutch with the predetermined characteristics. An actual signal of the rotational speed of the output shaft over time is measured during said process. Deviations are determined between the actual signal and the ideal signal. Finally the signal of the actuating pressure over time is automatically changed in order to reduce the deviations between the actual signal and the ideal signal if the deviations exceed a threshold.
