Engine - Oil Leaks
NOTE:
Before installing new gaskets or oil seals,
make sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet (UV) test:
Ultraviolet (UV) Testing
1. Clean the engine and transmission with a suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
WARNING: Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five minutes.
4. Switch off the engine.
NOTE: If no leak can be found, road test the
vehicle under various loads and check the engine
for leaks again.
5. Check the engine for oil leaks using a suitable UV lamp.
6. Rectify any leaks found and check the engine for oil leaks.
Measure the compression pressure
NOTE: The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are disconnected. This error message must be deleted
from the fault memory using the Ford diagnostic
equipment after completing the compression test.
NOTE:
Valve clearance must be set correctly
before performing a compression test. Make sure
the engine is at the normal operating temperature.
NOTE: The varying design of compression
checking devices and fluctuating starter motor
speeds normally only allows for a comparison to
be made of the compression pressures in all
cylinders.

• Selector lever position and selector leverposition display
• Fluid leakage
• Transmission fluid level check
• Transmission fluid quality check
• Modification/retrofitting
• Mechanical damage to the transmission
When inspecting connectors, remember that the
plugs may only be disconnected when they are not
energized.
The transaxle electronics may be destroyed by
static charge. To prevent damage, it must be
ensured that the technician complies with the
corresponding safeguards.
NOTE: Refer to the service literature for an exact
description of these safeguards.
Towing the vehicle
E66463
In general, vehicles with the AW55 transaxle can
be towed. Vehicles must never be towed
backwards.
As a result of the reduced lubrication of the
transaxle during towing, the following must be
remembered:
• The selector lever must be in the 'N' position.
• The maximum towing speed must not exceed 50 km/h.
• The maximum towing distance must not exceed 50 kilometers.
Push-starting the Vehicle
No torque is transmitted when towing or pushing
the vehicle. For this reason, vehicles with an
automatic transaxle cannot and must not be
tow-started or push-started.
Jump-starting the Vehicle
CAUTION: When jump-starting the vehicle
using a jumper lead there may be voltage
peaks. These may destroy the transaxle
electronics.
NOTE: When jump-starting the vehicle, the external
battery must remain connected for several minutes.
The voltage peaks dissipate after a few minutes.
Only then may the external battery be disconnected
without the risk of damage.

Transmission Fluid Level Check
E126079
WARNING: Beware, risk of scalding when
checking the transmission fluid.
NOTE: Refer to the service literature for the exact
procedure and specifications.
In order for the transaxle to function properly, it is
vital that the transmission fluid level is correct. If the transmission fluid level is excessively low, this
becomes noticeable by a rattling noise at the fluid
pump, etc.
Always use transmission fluid to the indicated
specification (WSS-M2C924-A).
The transmission fluid temperature is determined
using IDS.
It must be ensured that the transmission fluid
temperature is within the range specified in the
workshop literature.
The following conditions must be met in order to
carry out the transmission fluid level check
correctly:
• Ensure that the transaxle is not in limp home
mode.
• Place the vehicle on a level surface.
• Move the selector lever to the 'P' position.
• Make sure that the parking brake is fully applied.
• Run the engine at idle speed.
• Move the transmission selector lever to all positions. In doing so, wait until the transmission
engages the corresponding range.
• Move the selector lever back to the 'P' position.
• Pull out the fluid dipstick.
When the predetermined transmission fluid
temperature is reached, the fluid level shown on
the dipstick must be in the middle between 'MIN'
and 'MAX'. In this case, the fluid level is correct.

Under normal conditions, the transmission fluid is
filled for the service life of the transaxle and does
not need to be changed.
Under high loads (driving with a trailer or in
mountains etc.) it may be necessary to change the
transmission fluid.
To drain the transmission fluid, remove the fluid
drain plug.
Proceed as follows when topping off the
transmission fluid:
• Remove the return line from the fluid cooler to the transaxle on the transaxle. Close off the
connection on the transaxle using a plastic plug.
• Join the return line to a transparent pipe. The transparent pipe ends in the fluid reservoir in
order to collect the fluid.
• To top off the transmission fluid, insert a transparent pipe in the guide tube of the dipstick
and add approx. 2.0 liters of transmission fluid. • Move the selector lever to the 'P' position and
allow the engine to run at idle speed.
• Switch off the engine if air bubbles become visible in the transparent pipe to the fluid
reservoir.
• Top off approx. 2 liters of transmission fluid and allow the engine to run at idle speed. Switch off
the engine if air bubbles become visible in the
transparent pipe to the fluid reservoir.
• Top up the transmission fluid until the fluid level for cold fluid is indicated on the dipstick in the
middle between 'MIN' and 'MAX'.
• Then check the transmission fluid level.
Refer to the service literature for the exact
procedure and specifications.
NOTE: If the transmission fluid has been changed,
the counter for fluid change intervals must be reset
using IDS.

• 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.
