The motor vehicle gearbox has multiple pinions mounted on a rotary shaft (2) and a hydraulic actuator to selectively connect one pinion to the shaft. Hydraulic fluid passages (19,20,22) are formed in the shaft to connect with different actuators and are supplied with pressure fluid. The shaft has an axial internal seating (13) to receive a fixed hub (14) which has the passages within it. |
