The hydraulic pressure is distributed to the
individual clutches and brakes in the valve body.
The hydraulic paths and the hydraulic pressure are
controlled electronically via three PWM solenoid
valves and five shift solenoid valves.
The shift solenoid valves S1-S5 are either in the
'open' or 'closed' state.
The control valves (SLT and SLS) regulate the
hydraulic pressure in accordance with the duty
cycle of the electrical PWM signal. The controlled
hydraulic pressure enables smooth shifting or the
generation of a defined slip through actuation of
the relevant clutches and brakes. The control valve (SLU) regulates the hydraulic
pressure in accordance with the duty cycle of the
electrical PWM signal. It controls the torque
converter clutch. The PWM control achieves
smooth engagement of the gears.
The shift timing is calculated by the TCM using the
accelerator pedal position and vehicle speed.
Under normal conditions, the gears are shifted and
the torque converter lockup is activated at low
engines speeds in order to reduce the fuel
consumption.
If the accelerator pedal is pressed down quickly,
the TCM switches automatically into kickdown
mode.

PWM- solenoid valve – TCC (SLU)
E112325
Installation position
The PWM solenoid valve for the TCC (SLU) is
located in the valve body on the front of the
transaxle.

The valve actuates the torque converter clutch as
well as the reverse gear brake (B3) and 2nd - 5th
gear brake (B2). The PWM control achieves
smooth engagement of the gears. The two brakes
are actuated in 1st and 2nd gear to guarantee
engine braking.
The valve also actuates the torque converter in
such a way that is works in three positions: 'open',
'controlled looping (slip lock-up mode)', and 'locked
(full lock-up mode)'. The hydraulic function of the
valve is linear.
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.
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 temperature of the
transmission fluid increases in slip mode.

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.
