Note
Gearbox adaption is a very complex subject. Only basic principles and general
topics are discussed in the content of this Self-Study Programme. You will find
further information in the relevant expert training course.

The task of the adaption function is to compensate
for production tolerances in gearbox components
and changes which occur during their service life.
The adaption values serve as corrective values,
or so-called offsets, which are either added to or
subtracted from the default values (applied values)
stored in the gearbox control unit.

Introduction
A prerequisite for good and consistent shift quality,
in additon to the design, is precision control of the
shift elements. This is the purpose of the gearbox
adaption feature. In order to maintain constant shift
quality during the entire service life of the gearbox,
it is necessary to continuously adapt the various
open and closed-loop control parameters and save
acquired adaption data. These adjustments and the
teach-in process are collectively defined as
"adaption".
