Abstract
A shifting apparatus for use in a motor vehicle having an automatic transmission including a shift position select lever. The shifting apparatus includes an operator input means including a plurality of push buttons, each push button corresponding to desired transmission shift position. A generator means, operative in response to actuation of a push button, generates a signal representative of a desired transmission shift position. An actuator module, drivingly connected to the transmission shift position select lever, includes a variable resistance circuit which maintains a resistance value representative of the present transmission shift position. By reading the resistance value of the circuit, a comparator means can determine the present transmission shift position of the vehicle. Upon receiving an operator signal representative of a desired transmission shift position that is different from the present transmission shift position, the comparator means energizes the actuator module to move the shift position select lever to a position corresponding to the desired transmission shift position. The shifting apparatus of the present invention also operates in a security mode wherein…
