The transmission range selector is located on the
center console and is mechanically connected to
the transmission by a cable for operation of the
gear selector shaft and the TR (transmission range)
sensor.
As well as the positions P/R/N/D, the transmission
range selector provides a position for the sport and
select-shift mode (S). The manual gear position
can be selected at any time while driving. The gear selected is locked until the driver selects another
gear.
The engine can only be started in 'P' or 'N' position.
The selector cable adjustment mechanism is at the
transmission end of the selector cable.

Depending on the input signals, the TCM mounted
on the transaxle actuates the solenoid valves
S1-S5 in the valve body. The solenoid valves are
either in the "open" or "closed" state.
The (SLT and SLS) control valves regulate the
hydraulic pressure according to the pulse/pause
ratio 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 shift timing is calculated by the TCM using the
accelerator pedal position and vehicle speed.
Under normal conditions, gear shifting and torque
converter lockup occur at low engine speeds to
reduce fuel consumption.
If the accelerator pedal is pressed down quickly,
the TCM switches automatically into kickdown
mode.

Knowing and Understanding Customer
Concerns
Knowing and understanding customer concerns is
necessary in order to perform diagnosis.
First of all, ask the customer under which operating
conditions the problem occurs. If possible, try to
reproduce the concern by road testing the vehicle
with the customer.
You should be familiar with the following operating
conditions:
• Engine operating state
– Cold, warm-up phase, or at operatingtemperature
• Ambient temperature – Below 0 °C (32 °F), 0 to 20 °C (32 to 68 °F),or above 20 °C (68 °F)
• Road conditions – Good, poor, or off-road
• Vehicle load status – Unloaded, loaded, or fully loaded
• Transaxle status in manual mode – Upshift, downshift, overrun or acceleration
Testing Possible Causes of Transmission
Control Faults
Before performing a symptom-based diagnosis,
first carry out checks to eliminate various other
potential causes of the fault.
These situations include:
• Battery state of charge
• Defective fuses • Loose or corroded cables or electrical
connectors
• Ground connections to the transmission
• Retrofitted add-on units which are not approved by Ford, such as air conditioning, car telephone,
cruise control
• Unapproved tire sizes
• Incorrect tire size programmed with IDS (Integrated Diagnostic System)
• Engine tuning
IDS Diagnosis
NOTE: Customer concerns relating to the transaxle
can also be caused by engine-related faults.
The transmission control system of the AW55 is
closely linked to the engine management system.
Faults in the engine management system may
affect the transmission control system.
Before repairing the transaxle, it should be ensured
that the fault is not caused by the engine
management system or other non-transaxle
components.
The diagnosis can be performed on the AW55 with
the aid of von IDS.
visual inspection
A thorough visual inspection of the transaxle is
necessary for successful diagnosis.
A visual inspection is made of the following
components:
• Connectors and plug connections
• Ease of operation of the selector lever

NOTE:Due to static charging, measurements
inside the transaxle using a multimeter are
prohibited.
Stored DTCs in the engine management system
may affect transmission control. As a result, faults
in the transmission control system and engine
management system must be rectified in
accordance with the symptom-based diagnosis in
FordEtis IDS.
Applications of IDS Standard include:
• Resetting the counter for fluid change intervals.
• Programming the selector lever position 'N'.
• Resetting the values learned by the TCM.
Resetting the counter for fluid change
intervals.
This function must be performed if the transmission
fluid has been changed or a new automatic
transaxle has been installed with the previous TCM.
This function resets the values stored for the
pollution level of the transmission fluid.
Programming the 'N' position of the TR
sensor
This function must be executed if
• the TCM with integrated TR sensor is renewed,
• a new automatic transaxle is installed with the previous TCM.
• the selector lever cable or the selector mechanism assembly is renewed
• TR have been set due to a fault in the selector lever assembly or in the DTC (diagnostic trouble
code) sensor.
The TCM learns and stores the voltage value in
the 'N' position when this function is executed.
Resetting the values learned by the TCM
This function must be executed if
• a new automatic transaxle is installed with the previous TCM.
• a component of the automatic transaxle has been renewed.

Transmission Description – System Operation and ComponentDescription
System Operation
E112576
The AW55 5-gear automatic transaxle is a fully
automatic, electronically controlled automatic
transaxle. The fifth gear is an overdrive which
saves fuel.
The maximum input torque is 330 Nm.
Gear changes are controlled by an
electro-hydraulic system.
The gear ratios are achieved by means of a
combined planetary gear set and a Simpson set.
Three multi-plate clutches, four multi-plate brakes
and one band brake as well as two one-way
clutches control the various ratios.
The clutches and brakes are hydraulically operated
by electrically actuated solenoid valves. The valves
are actuated by the TCM depending on the driving
conditions and the driver's requirements.
The TCC is activated in gears 3, 4 and 5. The TCC
is driven in interlock mode and in slip mode. Defined slip achieves a smooth and therefore
comfortable clutch engagement of the TCC.
Control of slip mode depends on the engine speed,
accelerator pedal position and vehicle speed
signals provided by the ECM (engine control
module). This controls the rate of slip by comparing
the engine speed and the turbine shaft speed.
The TSS sensor and the OSS sensor use the Hall
effect principle. The TCM can regulate the slip in
the torque converter by comparing the engine
speed with the transmission speed.
All parameters for actuating the clutches and the
TCC are determined by the TCM as a function of
the operating parameters. The automatic transaxle
features a self-learning strategy.
The fundamental parameters for gear shifting are
the accelerator pedal position and the vehicle
speed.
Gear selection can either be performed
automatically or in select-shift mode. The selected
