Abstract
A control system for controlling a dual clutch transmission having a synchronizer assembly includes a motor for selectively providing an output torque in a first and second to both of a first and a second output member. A one-way device is interconnected to the first output member and is operable to transmit the output torque in the first rotational direction. A pump is connected to the one-way device. A disconnect device is interconnected to the second output member. The torque disconnect device is operable to decouple the motor from a cam or a torque multiplication device. The cam includes at least one groove having a configuration corresponding to synchronizer assembly positions. A shift fork is disposed in the groove and is operable to translate the synchronizer assembly. Rotation of the cam translates the shift fork and the synchronizer assembly between at least a neutral position and an engaged position.
