ABSTRACT:
A rotary shifting device is provided for use with an automatic transmission of a motor vehicle. The rotary shifter device includes a rotary shifter handle that is a flat disc. A cavity is located in the center of the lower side. A positioning probe extends from the lower side of the rotary shifter handle. A rocker is located within the cavity in the rotary shifter handle. A rotary shifter positioner is secured to the top plate of an enclosure in which a rotary shifter assembly is located and which transfers the rotary motion of the handle to a push and pull motion of an actuating bar which is connected to a transmission to provide gear selection. The rotary shifter positioner includes a groove with two slots at one end for park and reverse. The rotary shifter handle tips on the rocker to permit movement of the rotary shifter handle to permit placement of the positioning probe into one of the slots while preventing access to the slots by merely rotating the rotary shifter handle.
