Control Modules, Electronic Components and Contacts
♦ Only touch electrical components after discharging static elec‐
tricity on a grounded object, for example by touching (skin
contact) vehicle or vehicle lift.
♦ Connector contacts in electric connectors, control modules
and electrical components must not be touched with the hands

Transmission Adaptation

In addition to the construction, the deciding factor for good and
constant shift quality is the precise control of the shifting ele‐
ments. To maintain a consistent shift quality throughout the entire
transmission service life, various control and regulation parame‐
ters must be adapted continuously and the determined adaptation
values must be stored. These adaptations or this programming
process are called adaptation.
The goal of a transmission adaptation is to compensate for pro‐
duction tolerances of the transmission components and their
changes throughout the service life. The adaptation values act as
corrective values or offsets which are added to or subtracted from
the values (applied values) stored permanently in the transmis‐
sion control module.
When should the adaptation values be read, evaluated or erased
and when should an adaptation drive be performed?
♦ If the customer indicates there is rough or hard shifting be‐
havior.
♦ After replacing the ATF.
♦ After repairing the clutches.
♦ After replacing the valve body
♦ After replacing the Transmission Control Module - J217-
♦ After replacing the transmission
♦ After a software update.
