1. A system comprising: a transmission control circuit including a memory having a plurality of instructions stored therein that are executable by the transmission control circuit to change a value stored in the memory to a different value upon detection of user selection of a predefined sequence of two or more of a plurality of user selectable inputs, wherein the value relates to operation of an automatic transmission, and wherein the plurality of user selectable inputs comprises at least one of (i) a reverse (R) input to which the transmission control circuit is responsive to user selection thereof to control the automatic transmission to a reverse gear, (ii) a drive input (D) to which the transmission control circuit is responsive to user selection thereof to control the automatic transmission to a forward gear, and (iii) a neutral input (N) to which the transmission control circuit is responsive to user selection thereof to control the automatic transmission to a neutral state.
