A method of providing improved control and response to an electronic transmission range selection system comprehends providing a virtual null position for the electronic transmission range selection device including the steps of determining the current position of the shift lever, confirming the position of the shift lever, virtual Null and physical Reverse to Neutral confirmation timer thresholds are selected, the timers are incremented, a determination is made that the timers have started, a determination is made that the virtual Null timer has expired, whereupon a virtual Null request is generated. Subsequent steps determine if the physical Neutral timer has expired and command the transmission to Neutral. In related method steps, a current range of the transmission is determined, the state of a shift interlock button is determined, and certain shift changes are accepted or rejected.
