Abstract
A control system for an automatic transmission includes a double transition shift detection module and first and second clutch control modules. The double transition shift detection module detects whether a double transition shift operation is requested. The first clutch control module controls two of four transitioning clutches of the transmission during an inertia phase of the double transition shift operation. The second clutch control module controls each of the four transitioning clutches of the transmission during a torque phase of the double transition shift operation.
