A manual transmission

A manual dual clutch transmission comprises a first shaft 25, at least one first idler gear 29, 30 and a first selector sleeve 31 movable between a first gear position coupling the first idler gear 30 to the shaft 25 and a neutral position permitting rotation of the idler gear 30 relative to the shaft 25. A first cam follower 58 moves the first selector sleeve 31 along the shaft 25. A first selector shaft 39 is displaceable for displacing the cam follower 58 in the direction of the shaft 25 and carries a first coupling body 41 which is rotatable about a longitudinal axis 40 of the selector shaft 39 between an active position acting on the cam follower 58 and a passive position decoupled from the cam follower 58. Selector shaft 39 is displaced by a grooved cam 67 which is rotated by an actuator 47. The cam 67 moves a pin 44 engaged with a sleeve 56 that is fixed the selector shaft 39. A second selector shaft 38 may displace the cam follower 58 from neutral to a second gear position.
