<p>A manually operated transmission, for commercial vehicles having a plurality of synchronized forward gears and one unsynchronized reverse gear and optionally one unsynchronized crawler gear with synchronizer packets for the forward gears and locking plates, has a locking part (3) upon the gearshift bar (1) for the unsynchronized reverse gear or the gearshift bar for the unsynchronized crawler gear disposed in a manner such that when selecting the gate for the reverse gear or the crawler gear it engages without force in the adjacent gearshift bar (1) for one of the synchronized forward gears so that they are driven along in the shifting direction and thereby an ansynchronization of the forward gear adjacent to the gearshift bar (2) occurs, but a complete gearshift of the forward gear is prevented.</p> |
