摘要
A valve body assembly for a hybrid drive unit includes a pressure regulator valve, a first on/off shift valve for controlling a stationary clutch, a second on/off shift valve for controlling a rotating clutch, and a third on/off shift valve for controlling a damper bypass clutch. The control system controls the stationary clutch and the rotating clutch to operate the hybrid drive unit in four different modes. The first shift valve, the second shift valve and the third shift valve do not include a regulated pressure feedback port, nor a pressure switch for indicating a clutch fill level.
