The invention concerns a transmission shift system with a synchronizing arrangement. A rotary shaft and a gear rotating at different speeds can be coupled together with positive engagement at synchronous speed, by means of an annular sliding sleeve axially movable by a gearshift force, wherein a clutch gearing of the sliding sleeve meshes in a corresponding clutch gearing of the gear or of a clutch body connected with the gear. Between the sliding sleeve and the gear is situated a synchronizer ring. Parts of the gear or of the clutch body together with parts of the synchronizer ring form a positively engaged clutch. In the absence of synchronism, the axial movement of the sliding sleeve is locked by blocking faces of a locking device, the clutch gearing (4, 12) and the locking device (8, 16) being separated from each other. The clutch gearing (4) of the sliding sleeve (6) and the clutch gearing (12) of the gear or clutch body (14) have stub ends. At least one elastic element (26) is provided for dampening the clutch gearing (4, 12). The initial gearshift force (18) can be stored. A ratchet device (20) can be provided to hold fast the sliding sleeve (6) against the force of the elastic element (26) after elimination of the gearshift force (18)(FIG. 4D).
