摘要

The multi-stage automatic gearbox (1), for a motor vehicle, has a number of switch units (C1-C3,B1,B2) to select the gears for the required transmission flow (20). An additional switch unit (C4) gives a fifth direct gear with a reduction ratio of 1 by coupling the input shaft (4) directly to the output shaft (5).
