摘要

The transmission unit (1) has a starting unit (2) installed between the input (E) and output (A), and a RPM/torque converter unit (3) connected to it. An intermediate chamber (17) communicating with the outside environment is provided between the starting unit and RPM/torque converter unit and bounded by these at least in the axial direction. The separate ventilation passage or chamber (16.1,16.2,16.3) for the starting unit is connected to the intermediate chamber.
