This is one of the system components where the actuators, position sensors, actuator solenoid valves have been incorporated, specifically connected by cables that link them to a centralised multiple connector.
This solution simplifies and cuts down assembly time on the gearbox and avoids connection errors. Furthermore the actuator solenoid valve cables all have identification labels.
