The invention relates to a transmission module ( 10 ) for an engine-transmission unit, said module comprising an input shaft ( 11 ) for connecting to a heat engine, an output shaft ( 12 ) for connecting to a gearbox, and a clutch ( 30 ) connecting said two shafts. The inventive module also comprises: an independent casing ( 16 ) comprising a first half-shell ( 17 ) and a second half-shell ( 18 ), said two half-shells forming a sealed receiving element ( 22 ) containing the clutch ( 30 ) which is naturally in the engaged position; a mechanical element ( 35 ) for maintaining the clutch ( 30 ) in said engaged position by means of a piston in the form of a disk; a hydraulic control circuit ( 40, 41 ) for acting directly on the piston against the mechanical element, in the disengaged position of said clutch ( 30 ); and a hydraulic circuit ( 50, 52, 53, 55, 56 ) for lubricating and cooling the clutch. The invention can be applied to an engine-transmission unit for motor vehicles.
