ABSTRACT:
In a vehicle multi-ratio transmission comprising a plurality of change-speed gear trains, including a backward directional gear train, with which synchronizer clutches are associated for actuating same, two multidisc-type synchronizer clutches (12) are employed for actuating one of forward directional gear trains, which is operated under a heavy condition, and for actuating the backward directional gear train. Cone-type synchronizer clutches (11) are employed for actuating the other gear trains. Seizing of clutch members as well as an unexpected start of the vehicle at a neutral condition of the transmission are well prevented and increase of cost for securing these advantages is suppressed.
