1. A transmission gear and clutch shifting apparatus for the automatic operation of a manual gear shift mechanism in an automotive vehicle, the automotive vehicle having a gear shift lever with a plurality of manual shift positions, said gear and clutch shifting apparatus including:
- a gear shift mechanical actuation means mounted in the vehicle and coupled to the gear shift lever having a first flexible cable for causing actuation of the gear shift lever along the longitudinal axis of the vehicle, and a second flexible cable for causing actuation of the gear shift lever along the transverse axis of the vehicle,said gear shift mechanical actuation means including a first coupling slot means having an elongated slot generally aligned with the transverse axis of the vehicle for passing the gear shift lever and being coupled to said first flexible cable by a rotation means so that motion of said first flexible cable along the transverse axis of the vehicle causes motion of the slot of said first coupling slot means along the longitudinal axis of the vehicle,said gear shift actuator further including a second coupling slot means having an elongated slot generally aligned with the longitudinal axis of the vehicle for passing the gear shift lever and being coupled to said second flexible cable for causing motion of the gear shift along the transverse axis of the vehicle;
a first cable electronic actuator means mounted outside the vehicle and coupled to said first cable;
a second cable electronic actuator means mounted outside the vehicle and coupled to said second cable;
a clutch mechanical actuation means mounted in the vehicle and coupled to the clutch pedal, and including a third flexible cable for causing movement of the clutch; and
a third cable electronic actuator means mounted outside the vehicle and coupled to said third cable.
