Abstract
A multi-step transmission having at least a reverse drive gear, several forward drive gears, a main shaft () and two counter shafts. The power flow in forward drive can be split up and be distributed to both counter shafts and further transferred to the main shaft (). The forward drive gears each include two counter shaft gears and one idle gear which is supported on the main shaft (). In contrast, only one of the two counter shafts () is assigned and associated with a reverse gear () such that the flow of power, in a reverse drive gear (), is transferred through a single counter shaft ().
