A motor vehicle transmission system includes a reduction device having at least an output shaft including a first gearwheel and a second gearwheel. A differential drive device is configured to distribute the torque from the reduction device to two half-shafts. The differential drive device includes a coupling device which, in a coupled position, transmits torque between a first element and a second element of the differential drive device, the coupling device further including an actuator. A radial plane, orthogonal to the axes X and W, passes through the first gearwheel and through the coupling device.
