Abstract

A motor vehicle transmission device is described. The transmission has an actuating unit, used for canceling a tooth-on-tooth position of coupling elements, wherein the actuating unit actuates a transmission brake when the tooth-on-tooth position is detected. The transmission also has a second actuating unit for actuating a disconnect clutch, the second actuating unit actuating the disconnect clutch when the tooth-on-tooth position is detected. The actuating unit for actuating the transmission brake and the second actuating unit for actuating the disconnect clutch are actuated in coordination with one another, in order to cancel the tooth-on-tooth position.
