Selector lock FORD KUGA 2011 1.G User Guide

The TCM detects uphill driving by comparing the
engine load transmitted by the PCM with the engine
speed. If the engine load increases and the engine
speed falls, then the TCM causes the transaxle to
shift to a lower transmission range in order to
increase the traction force.
Downhill driving
The TCM detects downhill driving by comparing
the engine load and engine speed values
transmitted by the PCM with the OSS sensor
signal. In order to prevent overloading of the
vehicle brakes, the TCM causes the transaxle to
shift to a lower transmission range.
Hill-hold function
If the vehicle is stopped on an uphill incline, the
TCM detects this through the faster drop in engine
speed compared with the drop in engine speed
when stopping on the flat. In this situation, the
hydraulics are actuated by the TCM in such a way
that the vehicle is prevented from rolling back. This
function is not used on steep inclines.
If the vehicle is parked on an uphill incline (ignition
switched off), the hill-hold function is not active
when pulling away.
Altitude correction
Lower air density results in reduced engine
performance. In order to compensate for this
operating situation, the TCM changes the shift
points.
Selector lever lock
To prevent the selector lever being accidentally
moved from the P or N position, the vehicle also
has an electrically operated selector lever lock.
This blocks the locking pin in the locking segment
and thus locks the selector lever in the P or N
position.
Shifting from P into another transmission
range
To be able to move the selector lever from P into
another transmission range, the ignition must be
switched on and the brake pedal must be
depressed (stop light switch on). The TCM detects
the position of the brake pedal via the CAN data
bus and the engaged transmission range from the
TR sensor.
The signal is then transferred from the TCM to the
select-shift switch module in order to activate the
solenoid valve in the selector mechanism
assembly.
In position P, the solenoid valve is activated and
the locking pin is pulled in so that the lock button
on the selector lever can be pressed as usual to
engage another transmission range.
In the selector mechanism assembly there is a Hall
sensor which is affected by a permanent magnet
on the gate of the selector mechanism assembly.
If the selector lever is moved from the P position,
both the Hall sensor and the selector lever lock
solenoid are simultaneously deactivated, to prevent
the selector from being kept in the N position.
If the ignition is set to "I" or "0" the solenoid valve
is deactivated. When the selector lever is in the P
position, it is mechanically locked because it has
no voltage.
Shifting from N into another transmission
range
The conditions are the same as for shifting from P
into another transmission range.
However, the lock button on the selector lever must
be pressed to be able to select R or P.

The transmission input shaft rotates in the
clockwise direction. All clutches and brakes on 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.

Input shaft:
The transmission input shaft rotates clockwise.
Clutch C2 (1) connects the transmission input shaft
with the sun gear. The sun gear rotates clockwise.
The rear planetary gear set rotates
counterclockwise. The front larger planetary gear
set rotates counterclockwise with the rear planetary
gear set as a single unit. The front smaller
planetary gear set rotates clockwise.
Brake B3 (2) blocks the ring gear in
counterclockwise direction. The front and rear
planetary gear carriers are turned clockwise by the
front smaller gear. The primary idler gear rotates
counterclockwise with the front and rear planetary
gear carriers as one unit.
Output shaft:
The secondary idler gear rotates clockwise. The
front annular gear rotates clockwise with the
secondary idler gear as a single unit. The front
planetary gear set rotates clockwise. The sun gear
rotates in counterclockwise direction.
Brake B5 (3) prevents rotation of the rear planetary
gear carrier. The rear annular gear rotates
clockwise. The front planetary gear carrier and the
final drive pinion rotate clockwise with the rearannular gear as one unit. The final drive rotates
counterclockwise.
Engine braking:
The power is transferred directly to the
transmission input shaft without one-way clutch
involvement. Engine braking is thus applied.
NOTE:
The clutch C2 and the brake B3 are only
activated at a speed below 7 km/h (approx. 4.35
mph) when shifting from a forward gear to the
reverse gear.
Service instructions
Towing procedure
Towing is only permitted travelling forwards, at a
maximum speed of 80 km/h and for up 80 km. The
gear selector lever must be in Neutral.
CAUTION: The vehicle must never be
towed backwards under any
circumstances.

Selector lever with integrated select-shift
switch module
E112332
The selector lever unit is located in the central
console. It is mechanically connected to the
transmission by a selector cable which moves the
gear selector shaft in the TR sensor.
The following components are integrated in the
selector lever assembly:
• Select-shift switch module
• Selector lever lock solenoid.
• Switch contact for selector lever position 'P'
• LED for the selector lever position display
The selector lever has the following positions:
• P: Park position
• R: Reverse gear.
• N: Neutral position
• D: Automatically shift between all gears
• S: Sport and select-shift mode (manual gearchanging)
If the selector lever is not in the 'P' position when
the vehicle is exited, a signal is transmitted to the
instrument cluster via the switch contact for selector
lever position 'P'. When the driver door is opened,
a message to move the selector lever to the 'P'
position appears in the instrument cluster and the
warning buzzer sounds. The vehicle cannot be
electrically locked if the selector lever is not moved
to the 'P' position.

Overview of the select-shift switch module
E112331
The select-shift switch module is located on the
upper trim of the selector lever unit. The module
is supplied with power by the TCM.
It uses the LIN databus to interact with the TCM,
for instance to activate the selector lever position
display.
It allows the automatic transmission gears to be
changed up and down manually via the signals of
the Hall sensors.
The select-shift switch module detects the selector
lever position 'P' and 'S' via the integrated selector
lever position sensors (Hall sensors).
A cable leading from the TCM passes directly to
the select-shift switch module and is used to control
the solenoid of the selector lever lock. The
switching solenoid receives its voltage supply
directly from the module.
In the event of a fault, a signal is transmitted to the
TCM where all DTCs are stored.
