The transmission input shaft rotates in the

input side are deactivated and no power is
transmitted to the planetary gear sets.
No force is transferred to the output shaft. The
brake B5 (2) locks the rear planetary gear carrier
on the output side. The parking lock (1) is not
activated. Since the transaxle input shaft is not
positively connected with the input side, the vehicle
will start to roll away if it is on an incline. The brake B5 is activated both in 'P' and in 'N'
position to reduce the cut-in pressure that
otherwise occurs if several brakes and clutches
are activated simultaneously when the selector
lever is moved to 'D' or 'R' position. Since the brake
B5 is activated both in first and second as well as
in reverse gear, this method reduces the total
number of transient effects.

direction.
The brake B3 is additionally activated in select-shift
mode to guarantee engine braking.

• Item 18: ISS (input shaft speed) sensor
– Supplies information on the transmissioninput shaft speed. Used for calculations, for
instance the shift process, checking the
torque converter lockup and for diagnosis of
the hydraulic/mechanical operations in the
transmission.
• Item 19: OSS sensor – Supplies information on the transmissionoutput shaft speed. Used for calculations, for
instance the vehicle speed and for diagnosis
of the hydraulic/mechanical operations in the
transmission.
• Item 20: TFT sensor – Supplies information on the transmission fluidtemperature. This information is used to
adjust the shift times and the fluid pressure.
• Item 21: TR sensor – Supplies the TCM with the information on thechosen transmission range. Starting is only
possible when the selector lever is in the P
or N position. The sensor is a permanent
magnet which creates a magnetic field over
the different Hall sensors and in this way
creates a specific voltage for each shift
operation.
Via the LIN data bus
• Item 7: Selector lever module (select-shift module)
– Indicates that the selector lever is locked inposition P and supplies information on the
sport mode status. Also transmits a control
signal during select-shift gear changes and
supplies information on the fault status in the selector lever module, so that the fault codes
in the module can be stored as required.
Via the CAN data bus
• Item 4: PCM – Stop light switch ON/OFF, is used by theTCC.
– Coolant temperature, used for diagnosis of the transmission temperature sensor and for
activating the catalytic converter.
– Engine speed >400 rpm = engine running. Used for starting the transmission fluid
pressure and diagnosis functions.
– Engine rpm. Used for checking the torque converter slip and the pressure build-up,
which have an effect on the shift comfort.
– Kickdown. If the accelerator pedal is pressed down and the throttle plate is wide open, the
PCM transmits a kickdown signal to the TCM.
– Current engine speed, used to check the line pressure of the transmission.
– Throttle plate opening, used to calculate the gear changes. During sport mode and
kickdown.
– Accelerator pedal position, used to calculate the shift threshold timings.
• Item 5: ABS module – Supplies information on the vehicle speedand also on the difference in speed between
the left-hand and right-hand wheels. Prevents
changing up if the speed difference is greater
than 40 km/h, to protect the differential in the
transmission.
• Item 6: Vehicle speed control system – Is used to calculate the acceleration,depending on the position of the resume and
set buttons.
