Patent ID: 8216111

Claim:
A system for controlling a transmission, comprising: a first torque transmitting mechanism that is engageable to achieve a first gear ratio of the transmission; a second torque transmitting mechanism having an apply chamber, wherein the apply chamber 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 where the first pressure level is less than the second pressure level, and wherein the second engaged position achieves a second gear ratio of the transmission; a controller in communication with the first and second torque transmitting mechanisms, wherein the controller includes: a first control logic for monitoring a first transmission operating condition when the transmission is in the first gear ratio; a second control logic for determining if the transmission operating condition has exceeded a threshold operating condition; a third 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 the threshold operating condition; a fourth control logic for monitoring the engagement of the first torque transmitting mechanism; and a fifth control logic for determining if the first torque transmitting mechanism is disengaged.
