An electric shift apparatus (10) for shifting a vehicle transmission assembly (12) includes a mounting structure (20) adapted to be mounted to a transmission housing (22), an electric motor (24) supported by the mounting structure (20), and a drive assembly (26) operably driven by the electric motor

An electric shift apparatus (10) for shifting a vehicle transmission assembly (12) includes a mounting structure (20) adapted to be mounted to a transmission housing (22), an electric motor (24) supported by the mounting structure (20), and a drive assembly (26) operably driven by the electric motor (24). The apparatus (10) further includes a core element (28) movably supported by the mounting structure (20) and a guide (30) for guiding the core element (28). A terminal (32) is slidably disposed in the guide (30) and connected to the core element (28). A shift lever (34) is movable between a plurality of shift positions and connected to the terminal (32) for shifting a transmission. The apparatus (10) is characterized by the core element (28) comprising a helical cable (36) which is driven by the drive assembly (26) for linear actuation of the shift lever (34). The helical cable (36) is comprised of a filamentous member (38) and a core member (40) that defines a longitudinal axis (42). The filamentous member (38) is wound in spaced convolutions to define tooth-like members (44). The tooth-like members (44) are spaced apart from one another along the core element (38) and are in driven engagement with the drive assembly (26).
