The invention relates to a method for adapting a pressure characteristic line (6) of a friction-locking shifting element of a transmission of a motor vehicle. A rapid filling time is adapted for a rapid filling pressure via a process of adapting the rapid filling time of the friction-locking shifting element, and the reaction of the transmission to the rapid filling time adaptation is ascertained. The method has the following steps: a characteristic point on the pressure characteristic line (6) to be adapted is selected or taken on as the characteristic point to be adapted, said characteristic point then being adjusted when the shifting element is actuated in order to be closed using the rapid filling pressure for an actuation duration which is shorter than the adapted rapid filling time by a defined period of time; in order to adapt the pressure for said characteristic point, the shifting element is first actuated in order to be closed using the rapid filling pressure for a first duration, wherein the first duration is shorter than the adapted rapid filling time by the defined period of time; the shifting element is then actuated using a waiting pressure, which is lower than the rapid filling pressure, for a waiting time duration; the shifting element is then actuated using the rapid filling pressure for a second duration which corresponds to the defined period of time, and the reaction of the transmission to the adaptation is ascertained in the process; and if it is then ascertained that the reaction to the adaptation corresponds to the reaction to the rapid filling time adaptation, the current waiting pressure is defined as the pressure to be adapted for the characteristic point to be adapted of the pressure characteristic line to be adapted.
