I think the cable shift was introduced to help hold the cost down. The cars weren't moving, so I guess they had to try something.
The cable shifter, as its name implies, moves a cable that selects gears at the transmission. The shift by wire uses just a wire to tell which gear the trans should be in. I'm unclear myself as to whether there's an actual servomotor involved like on the old Edsel's pushbutton shift, or if it all happens in the transmission's software. Anybody know?
