Abstract:
The present invention provides a system for shifting or controlling a dual clutch transmission where the transmission may operate in at least a first mode of operation and a second mode of operation. The system includes a controller and a plurality of solenoids in fluid communication with a valve assembly. Selective activation of the solenoids by the controller engages the valve assembly to provide the first mode and the second mode of operation.
