A synchronized manual transmission of a motor vehicle is actuated by a shift roller. The transmission gears can be shifted only by the simultaneous closing of two synchronizer clutches. At least one sliding sleeve of a synchronizer clutch is adjustable independently of the position of the shift roller into the neutral position and inversely from the neutral position into the position determined by the shift roller.
