Abstract
The core transmission tasks introduced in Chap. 1 require the tasks of power transfer and shifting or modulation as described in Chap. 3. For the latter actuation and servo systems are needed to provide the ratio changes and to control the launch devices. The transmission must also be lubricated and cooled, and this is done with appropriate auxiliary systems. For this, the individual requirements and functionalities differ depending on the transmission design (see Chap. 6).

Notes
- 1.
This applies equally to a hydraulic or electro-hydraulic system; especially the volumetric losses (leaks) are significant then.
