ABSTRACT:
A hydraulic control unit for an automotive transmission has a change gear operating mechanism and a clutch operating mechanism. All component parts of the control unit are incorporated into one body. These include a first hydraulic actuator for gear shifting and gear selection of the speed change gear, solenoid valves for controlling the first hydraulic actuator, position sensors for sensing positions of the first hydraulic actuator indicative of the selected gear position and shifted gear position of the speed change gear, a second hydraulic actuator for engagement and disengagement of the clutch, solenoid valves for controlling the second hydraulic actuator, and a position sensor for sensing the position of the second hydraulic actuator indicative of engagement and disengagement of the clutch. An air breather provided on the control unit housing on the side of the speed change gear communicates with an air chamber of the second hydraulic actuator through a passage formed within the control unit housing, to also serve as an air breather for the same chamber.
