Title: Method for adapting a torque converter lock-up clutch

Abstract: For a torque converter lock-up clutch (7) a method is proposed in which an application pressure is adapted. To this end, within a first interval, a pressure change is output after a transition function and the existence of the reaction of the torque converter lock-up clutch is tested after output of the application pressure during an application phase from an electronic gear control (13). In the absence of reaction, additional intervals are then output. The application phase is then terminated when the reaction of the torque converter lock-up clutch occurs. The control/regulating phase for the torque converter lock-up clutch (7) follows after the application phase terminates.
