Abstract
The invention relates to a multi-stage transmission (130) for a drive unit (100) of a motor vehicle (105), comprising: - a first pressure valve arrangement (200) and a second pressure valve arrangement (203), which can be controlled separately and pressurized with a system pressure; - at least two clutches (221 - 226) for controlling a power flow through the multi-stage transmission (130); and - a first demultiplexer arrangement (230, 400) connected to the first pressure valve arrangement (200) and a second demultiplexer arrangement (233) connected to the second pressure valve arrangement (203).wherein the first demultiplexer arrangement (230, 400) is configured to fluidically connect only one selectable first of the at least two couplings (221 - 226) to the first pressure valve arrangement (200), and wherein the second demultiplexer arrangement (233) is configured to fluidically connect only one selectable second of the at least two couplings (221 - 226) to the second pressure valve arrangement (200). The invention further relates to a drive unit (100) for a motor vehicle (105) and to a motor vehicle (105) with such a drive unit (100).
