Abstract:
1. A transmission shifting system for a vehicle, the vehicle having a transmission having a member that is push and pulled to engage a gear and rotated when the transmission is in neutral for operating the transmission movable in an H pattern, the system comprising: a first reversible electric motor having an anti backlash gear assembly; said first motor coupled to the member for moving the member backwards and forwards in and out of gear; a second reversible electric motor having an anti backlash gear assembly; said second motor coupled to the member for rotating the member clockwise and counter-clockwise said second motor coupled to said member; biasing means coupled between said member and said second motor, said biasing means applies a biasing force to the member when the member is in a position wherein it can not rotate when said second motor is rotated; and transmission shifter control means for actuating said first and second motors to move the member in the H pattern upon receipt of an actuation signal; such that when the transmission is in gear and the member can not rotate, said second motor can be rotated to cause said biasing means to bias the member to rotate and once said first motor has moved the transmission into neutral, said biasing means will automatically rotate the member without said second motor rotating.
