A clutch pack system for transmission includes a push rod assembly, a clutch piston configured to transfer pressure received from the push rod assembly, a clutch friction plate configured to transfer pressure received from the clutch piston, and an outer hub connected to an outer drum by pressure from the clutch friction plate.

A compact park lock assembly configured to be pulled towards a ramped section of a locking lever during actuation to unlock and lock a park lock gear. The compact park lock assembly includes a guide plate configured to align the park lock assembly during assembly, receive input loads from a pinion drive gear arrangement, position and restrain movement of the guide plate, and provide for sensing of the position of the locking lever during operation. The compact park lock assembly also includes an abutment plate to facilitate mounting of the park lock assembly, a spring section to restrain the guide plate, and a clip section to force and retain the abutment plate section to a housing.

A gearbox actuator unit (14) is configured to be arranged on a gearbox (10) and includes a housing (22), a control device (24), and an actuator (28, 30). The housing (22) is configured to attach to a gearbox housing (12) and to seal the gearbox housing (12). The control device (24) is electrically connected to the actuator (28, 30) and activates the actuator (28, 30). A pinon of the actuator (28, 30) is configured to actuate a rack of a shift fork (18, 20) of the gearbox (10) and can be connected to the shift fork (18, 20) of the gearbox (10). The control device (24) and the actuator (28, 30) are arranged within the housing (22), with the pinion extending through an opening of the housing. A gearbox (10) with a housing (12) having an opening (44) receives the actuator unit (14), which closes and seals the opening (44).
