    摘要： A method of operating a clutch during vehicle launch including increasing a first hydraulic pressure in an inner chamber from a first to a second level; decreasing a second hydraulic pressure in an outer chamber from a third to a fourth level in response to engine speed and throttle position for the vehicle; and slipping the clutch in response to increasing and decreasing the first and second pressures, respectively. The first hydraulic pressure urges a clutch disposed between the engine and an impeller for a vehicle torque converter to an engaged position. The second hydraulic pressure opposes the first hydraulic pressure. In some aspects, the method includes determining a temperature for oil in a transmission in the vehicle. Then, decreasing the second hydraulic pressure includes decreasing the second pressure in response to the determined temperature. In some aspects, the clutch and the chambers are located in the torque converter.

    摘要： The present invention is a method of engaging a drive gear in a vehicle transmission having a torque converter that reduces the sudden vibration jolt that often accompanies engagement of a drive gear from a neutral position, such as Park or Neutral. The method includes sensing brake pedal depression, detecting shifting from a neutral gear to a drive gear, disengaging a pump clutch in the torque converter, with the pump clutch connecting a pump in the torque converter with a torsional input, such as from an engine, into the torque converter, and gradually engaging the pump clutch, with the gradual engagement occurring after a predetermined period of time after said gear lever shift movement has stopped. Also disclosed is a system that enables operation of the method.
