DESCRIPTION AND OPERATION
The transmission control unit can be diagnosed
with WDS via the DLC.
Gearshift strategies
Gearshift control
I A I Accelerator pedal position I
I B I vehicle speed 1
The current ratio is selected by the transmission
control unit either in accordance with the
requirements for low fuel consumption or in order
to meet the required driving performance.
The gearshift timing is selected in accordance with
a gearshift map which is programmed into the
control unit as a function of the accelerator pedal
position and the vehicle speed.
For kick-down (accelerator pedal pressed down at
least
95 %) the next lowest gear is selected, as
long as the engine speed allows it. All gearshift
timings are set by the transmission control unit to
the upper shift characteristic. The driver can feel the
kickdown point
in the
accelerator pedal as a slight increase in resistance
to the operation of the pedal.
This is influenced by the following variables:
accelerator pedal position and actuation,
vehicle speed,
brake pedal position,
selector lever position.
The following are actuated:
SSA shift solenoid valve,
SSB shift solenoid valve.
Hill climb mode
When the vehicle is in hill climb mode or towing a
trailer, the transmission control delays gearshifts
to prevent frequent shifting back and forth between
the gears.

DESCRIPTION AND OPERATION
Item Description
I I 1 Cover I
1 2 I Adjusting ring (ramp ring) I
1 3 1 Spring I
1 4 1 Sensing Belleville washer I
r5 1 Main Belleville washer I
A conventional clutch responds to clutch wear with
an increase in the release force, which ultimately
has to be delivered by the driver to press down the
clutch pedal.
This increase in the release force after clutch wear
is used on the self-adjusting clutch as the key
indicator for adjusting the clutch. The main
distinction to a conventional clutch is that
the main Belleville washer is not riveted in a fixed
-
manner to the cover, but instead is supported by (
a so-called sensing Belleville washer. In addition
an adjusting ring (ramp ring) is used to compensate
the wear of the clutch lining.
The sensing Belleville washer is hooked into the
clutch cover at the outside and, with the inner
tongues, forms the bearing for the main Belleville
washer.
The sensing Belleville washer is designed to deliver
a slightly greater opposing force under normal
conditions than the maximum required release
force.
Item Description
If when the clutch is operated the release force is
less than the opposing force of the sensing
Belleville washer, then the pivot bearing point of
the main Belleville washer remains in the same
position.
If however the release force increases due to lining
wear, then the opposing force of the sensing
Belleville washer is exceeded. If the
opposing force of the sensing Belleville
washer is exceeded, the sensing Belleville washer
and therefore also the main Belleville washer are
displaced towards the flywheel.
This displacement towards the flywheel has the
effect that the release force is reduced again.
Once the release force has dropped to the level of
the opposing force of the sensing Belleville washer
again (equilibrium of forces), the displacement of
the components towards the flywheel stops.
