The motor-vehicle transmission has a gearbox with at least one input shaft (11, 111; 111; 11), and a clutch unit (12) and a flywheel assembly which are mounted between the gearbox and a crankshaft (14) of the motor-vehicle. The clutch unit (12) comprises at least one dry clutch (13, 113; 113; 13) including a driven portion (48, 50, 148, 150; 148, 150; 48, 50) and a driving portion (41, 52, 54, 141, 152, 154; 141, 152, 154; 41, 52, 54), the driven portion (48, 50, 148, 150; 148, 150; 48, 50) being fast for rotation with the at least one input shaft (11, 111; 111; 11). The flywheel assembly is a two-mass flywheel (30) comprising a first engine-side mass (31) and a second gearbox-side mass (32) comprising the driving portion (41, 52, 54, 141, 152, 154; 141, 152, 154; 41, 52, 54) of the at least one clutch (13, 113; 113; 13). An element (34) of the first engine-side mass (31) is connected to the second gearbox-side mass (32) through a torsional damper (40). The second gearbox-side mass (32) is supported for rotation by a radial ball bearing (44), which is mounted on the at least one input shaft (11, 111; 111; 11) in such a manner that its outer race is clamped axially between a pair of shoulders provided by two elements (41, 141) of the second gearbox-side mass (32) and that its inner race is mounted in axial abutment on one side with a side of a splined portion (45) or of a shoulder formed on the outer cylindrical surface of the at least one input shaft (11, 111; 111; 11) and is clamped axially on the opposite side by means of a ring nut (46).
