An automatic manual transmission for a hybrid vehicle provided with an internal combustion engine and with an electrical machine;

• the automatic manual transmission comprises:
• a servo-assisted mechanical gearbox, which is provided with at least one primary, shaft suited to receive a torque from a crankshaft of the internal combustion engine, and with at least one secondary shaft;
• a differential gear, which transmits the motion to driving wheels;
• a clutch;
• a servo-assisted drive device with a variable gear ratio, which is arranged immediately downstream of the gearbox and directly receives the motion from the secondary shaft of the gearbox;
• an auxiliary shaft, along which the electrical machine is mounted;
• a drive shaft connecting the differential gear to the servo-assisted drive device,
• a first connectable/disconnectable and servo-assisted connection device, which is suited to connect the auxiliary shaft to the drive shaft;
• and
• a second connectable/disconnectable and servo-assisted connection device, which is suited to connect the auxiliary shaft to the secondary shaft of the gearbox.
