The invention relates to a hybrid transmission for a motor vehicle equipped with a heat engine (1) and with a main electrical machine (4a), comprising a solid input shaft (7) and a hollow input shaft (8) that is concentric with the solid input shaft (7), said shafts being connected respectively to the heat engine (1) and to the main electrical machine (9), and each of said shafts bearing at least one intermediate drive on an output shaft connected to the wheels of the vehicle, a first coupling means (C1, C3) between the output shaft and two pinions rotating idly about same, and at least one second coupling means (C2) that can occupy three positions in which: the heat engine (1) is uncoupled from the powertrain connecting the main electrical machine (4a) to the wheels, the heat engine (1) drives the wheels with the aid of the main electrical machine (4a), and the heat engine (1) and the main electrical machine (4a) are coupled such that the respective torques thereof are combined. The transmission also comprises a secondary electrical machine (4b) connected to the heat engine (1) and to the solid input shaft (7) by a planetary gear set (3).
