Definitions
- the invention relates to a transmission arrangement.
- control devices and electronic components such as sensors are used for different tasks. For example, in a transmission, rotational speeds of waves and positions of gear actuators are measured by means of sensors.

- the at least one further component group has at least one respective further sensor element and / or at least one respective further actuator.
- the at least one further components ⁇ group is signally coupled to the local control device via the bus ⁇ system.
