The fluid pump operates on the principle of a
G-rotor fluid pump.
The fluid pump draws transmission fluid from the
fluid pan, builds up fluid pressure and then supplies
it to the valve body.
The fluid pump is driven by the crankshaft via the
torque converter housing.

5 The torque converter transmits the output torque
hydraulically from the engine to the transaxle input
shaft.
The stator increases the torque up to the clutch
take-up point. At the clutch take-up point, the speed
difference between impeller and turbine is
approximately 90 %.
In order to improve the efficiency, the torque
converter features a hydraulically-activated TCC.
When the TCC is engaged, the torque is
transmitted directly from the crankshaft via the
torque converter housing to the transaxle input
shaft.
Installation position
The TCC is an integral component of the torque
converter.
Function
The TCM controls the PWM via the TCC solenoid
valve for the TCC (SLU). Based on the signals for
engine speed and accelerator pedal position as
well as vehicle speed, driving comfort is improved
by linear actuation of the TCC.

Full lock-up mode
In lockup mode the TCC is closed. The impeller
and the turbine of the torque converter are friction
locked. The engine torque acts directly on the
transmission input shaft. Fuel consumption is
reduced due to a reduction in the torque converter
pump losses.

Full lock-up mode of the TCC is not generated at
engine temperatures below 20 °C (68 °F).
Slip lock-up mode
In slip lock-up mode, slip in the TCC is permitted
in order to improve driving comfort. The hydraulic
pressure acting on the TCM varies in accordance
with the duty signal of the actuation signal
generated by the PWM for the TCC solenoid valve
for the TCC (SLU). The automatic transaxle
temperature increases in slip lock-up mode.
The TSS sensor
E112328
The TSS sensor is mounted at the top of the
transmission housing. It is an active sensor and is
supplied with 12 V.

The TSS sensor is a Hall sensor. It generates a
square-wave signal, the frequency of which varies
depending upon the speed of the transmission
input shaft.
The frequency of the square-wave signal increases
with the transmission input shaft speed. The TSS
sensor picks up the speed at the housing of the
1st - 5th gear clutch (C1).
The TCM uses the information from the TSS sensor
to determine the following parameters:
• Calculation of the torque reduction that needs to be requested by the PCM during shifting.
• Comparison of engine speed with transmission input shaft speed for calculation of torque
converter slip.
• Calculation of the shift points.
• Calculation of the engaging and disengaging point for the TCC (lock-up function).
• Calculation of the current gear ratios by comparison of the OSS sensor signal.

transaxle output shaft. The frequency of the
square-wave signal increases with the speed of
the transmission output shaft.
The OSS sensor picks up the speed at the gear of
the parking lock.
The TCM uses the information from the OSS
sensor for the following parameters:
• Calculation of the degree of torque reductionthat needs to be requested by the PCM during
shifting.
• Calculation of the shift points.
• Calculation of the engaging and disengaging point for the TCC (lock-up function).
• Calculation of the current gear ratios by comparison of the TSS sensor signal.

2 • The torque converter lockup and adaptation
functions are deactivated.
• The wheel speed signal is transmitted by the ABS to the TCM via the HS-CAN data bus. This
signal serves as a substitute value.
• When the engine is restarted (ignition switched off for approx. 15 seconds), the transaxle is no
longer in limp home mode. There is no longer
a fault indication on the instrument cluster, and
the MIL is off. However, the fault remains stored
in the TCM. If the fault is still present, limp home
mode is reactivated.
The TFT sensor
E125802
The TFT sensor is located in the valve body and
is an integral component of the internal transaxle
wiring harness.
