A method for releasing a tooth-on-tooth position of an interlocking shift element (6) of a transmission (5) or an interlocking shift element between two transmissions, such that the tooth-on-tooth position is released by using an actuator, in particular by using a transmission brake (8) or a drive clutch (7), and when a tooth-on-tooth position to be released is recognized, then depending on a drive-side or input-side rotational speed of the interlocking shift element (6), depending on a synchronous speed of the same and as a function of the actuators (3, 7, 8) available for releasing a tooth-on-tooth position, at least one actuator is selected, by using which the drive-side or input-side speed of the interlocking shift element (6) is approximated to its synchronous speed.
