The present invention relates to a gear shift system for a motor vehicle with a steering wheel. Said gear shift system comprises gear shift devices rotationally integral with the steering wheel, each of which is operable by a driver of the motor vehicle to carry out at least one respective gear shift function associated with said gear shift device. Furthermore, said gear shift system further comprises an electronic control unit configured to: receive a magnitude indicative of a current steering wheel angle; determine, on the basis of the received magnitude, whether the current steering wheel angle satisfies predefined conditions; and, if it determines that the current steering wheel angle satisfies the predefined conditions, reconfigure the gear shift functions associated with the gear shift devices.
