# Method for adapting a pressure characteristic line of a friction-locking shifting element of a transmission, and controller

## Abstract

A method for adapting a pressure characteristic curve of a friction-locking shift element of a transmission of a motor vehicle includes actuating the shift element using a rapid filling pressure for a first time, shorter than an adapted rapid filling time by a defined period of time. The method further includes subsequently actuating the shift element using a waiting pressure for a waiting time, the waiting pressure being lower than the rapid filling pressure. The method further includes subsequently actuating the shift element using the rapid filling pressure during a second time, equal to the defined period of time, and ascertaining a reaction of the transmission to adaptation. Additionally, the method includes determining, when the reaction of the transmission to the adaptation corresponds to a reaction to the rapid filling time adaptation, a pressure at a characteristic point on the curve being adapted as the waiting pressure.
