Abstract
An arrangement for reducing rattling in a transmission of counter shaft design having first countershafts (3, 4) and a load-equalizing main shaft (7) in which each transmission ratio step comprises a loose wheel (6), arranged on the main shaft (7), and a respective fixed wheel (5) arranged on each of the first and second countershafts (3, 4) which are in active engagement with one another. Activation of the transmission ratios occurs by actuating a shift element (8) such that the respective loose wheel can be connected, in a rotationally fixed manner, to the main shaft (7). In this arrangement the oil pump (13) of the transmission is mounted on the main shaft (7).
