Shift by wire

A commercial push-button-based electronic shift selector made by Allison Transmission

Shift by wire is the system by which the transmission modes are engaged/changed in an automobile through electronic controls without any mechanical linkage between the gear shifting lever and the transmission. The transmission shifting was traditionally accomplished by mechanical links to put the vehicle in Park, Reverse, Neutral and Drive positions through a lever mounted on the steering column or a gear shifter near the center console.

This eliminates routing space required for housing the mechanical linkages between the shifter and the transmission and provides effortless shifting through the press of a button or through knobs. Elimination of this linkage removes any shift effort from the driver’s gear selection.
