  • Clutch control for a transmission
    Patent number: 8216111
    Abstract: A system and method for controlling torque includes a first torque transmitting mechanism and a second torque transmitting mechanism. The first torque transmitting mechanism is engageable to achieve a first gear ratio of the transmission. The second torque transmitting mechanism has an apply chamber that is pressurized at a first pressure level to achieve a first engaged position and is pressurized at a second pressure level to achieve a second engaged position. The first pressure level is less than the second pressure level and the second engaged position achieves a second gear ratio of the transmission. A controller is in communication with the first and second torque transmitting mechanisms. The controller includes a control logic for pressurizing the apply chamber of the second torque transmitting mechanism to the first pressure level if the first operating condition has exceeded a threshold operating condition.
