Abstract
The invention provides a method of and an implementing assembly for shifting the transmission 12 of a vehicle having a battery 24 between park and various shift positions with a reversible motor 10 by supplying electrical energy from the battery 24 to the motor 10 to shift the transmission 12 in response to a shift selection 14 and characterized by storing electrical energy in a super capacitor 20 and transmitting that electrical energy stored in the capacitor 20 to the motor 10 for actuating the motor 10. The capacitor is placed in parallel with the battery 24 for charging the capacitor and in series with the battery 24 and the motor 10 to transmit the stored energy of the capacitor to the motor 10. The capacitor 20 stores sufficient electrical energy to actuate the motor 10 independently of the battery 24.
