  • Method for disengaging hydraulic park without engine power
    Patent number: 10703369
    Abstract: In a special operating mode, a controller is programmed to disengage a hydraulically actuated park mechanism without use of engine power. The starter motor is used to rotate the engine-driven pump at sufficient speed to command disengagement of Park. Once park is disengaged, a holding pin is used to maintain the out of park condition without hydraulic pressure or flow.
    Type: Grant

  • Control of sequential downshifts in a transmission
    Patent number: 8113989
    Abstract: A method for executing a downshift in a transmission includes starting disengagement of a second control element after starting disengagement of a first element. Disengagement of the second element starts before starting engagement of a fourth element. A third element is forced to synchronous speed by beginning engagement of the fourth element before engaging the third element. Engagement of the third and fourth elements is completed at the end of the downshift.
