The invention relates to a manual gearbox (10) for a motor vehicle, comprising an input shaft (11), an output shaft (12) arranged coaxially to the input shaft (11), a first layshaft (13) arranged parallel to said input shaft (11), and a plurality of shiftable gears (1-6, L, R). Associated with each gear are an idler gear (L1-L6, LC, LR) and a gear-shift coupling (17, 18, 20-25) by means of which said idler gear (L1-L6, LC, LR) can be connected to one of the shafts (11, 12, 13) in a rotationally-fixed manner. One of the idler gears (L1) is designed as an intermediate gear sitting on one of the shafts (11, 12, 13) of the manual gearbox (10) and engaging with one first pinion (F1) and one second pinion (26) that sit on two other shafts of the manual gearbox (10). According to the invention, the manual gearbox (10) is characterised in that the intermediate gear (L1) is connected, in a rotationally-fixed manner, to the input shaft (11) irrespective of the shift-state of the individual gears (1-6, L, R).
