摘要： Auxiliary transmission actuation mechanism 200 in a power transmission unit of a vehicle includes a transmission actuating gear 202, a gear driven bush 204, a gear actuating means 206, a shift fork 208, a shift rail 210, a clutch control valve actuating arm 212, a rail shifting means 214. The transmission actuating gear 202 is used to drive at least one of an even shaft and an odd shaft which in turn drives an output shaft through gears thereby propelling the vehicle when at least one of a dual clutch unit and a hydraulic system of vehicle is not functioning. The clutch control valve actuating arm 212 is adapted to engage a movable member of a clutch control valve assembly 100V thereby actuating clutch control valve 100V to de-actuate the dual clutch unit.
