A five-speed change-speed transmission, especially for sports-type vehicles, in which the shifting channels for fourth and fifth speed are disposed in one plane of rotation of the shifting shaft, the shifting channels for the second and third speeds are disposed in a second plane of rotation of the shifting shaft, the shifting channel for the first speed is disposed in a third plane of rotation adjacent to the second plane of rotation and the shifting channel for a reverse speed is disposed in a fourth plane of rotation of the shifting shaft, offset to the third plane of rotation in the axial direction of the shifting shaft; during a shifting down operation, the shifting shaft is normally prevented from reaching the third or fourth plane of rotation by a locking device which can be rendered ineffectual by operation of a push-button or the like at the shifting lever. |
