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.
