2002 FORD EXPEDITION transmission

R (Reverse)
With the gearshift lever in R
(Reverse), the vehicle will move
backward. Always come to a
complete stop before shifting into
and out of R (Reverse).
N (Neutral)
With the gearshift lever in N
(Neutral), the vehicle can be started
and is free to roll. Hold the brake
pedal down while in this gear.
(Overdrive)
The normal driving position for the
best fuel economy. Transmission
operates in gears one through four.
(Overdrive) can be deactivated
by pressing the transmission control
switch (TCS) on the end of the
gearshift lever.
The transmission control indicator
light (TCIL) (the word OFF) on the
end of the gearshift lever will
illuminate.
Drive± Not shown on the display. Activate by pressing the transmission
control switch (TCS) on the end of the gearshift lever with the gearshift
in the
position. The TCIL (the word OFF) will illuminate on the
gearshift lever. Transmission operates in gears one through three.
(Drive) provides more engine braking than(Overdrive) and is useful
when:
²driving with a heavy load.
²towing a trailer up or down steep hills.
²additional engine downhill braking is desired. If towing a trailer, refer
toDriving while you towin theTrailer towingsection.
To return to
(Overdrive) mode, press the transmission control switch
(TCS). The TCIL (the word OFF) will no longer be illuminated.

Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired.
2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low) at
higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
Forced Downshifts
To gain acceleration in(Overdrive) or Drive (O/D OFF) when
passing another vehicle, push the accelerator to the floor. The
transmission will downshift to the appropriate gear: third, second or first
gear.
Shift strategy (4R100 automatic transmission)
To account for customer driving habits and conditions, your 4R100
automatic transmission electronically controls the shift quality by using
an adaptive learning strategy. The adaptive learning strategy is
maintained by power from the battery. When the battery is disconnected
or a new battery is installed, the transmission must relearn its adaptive
strategy. Optimal shifting will resume within a few hundred kilometers
(miles) of operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.

FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
When Four±wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD power can be selected when
additional driving power is desired.
If equipped with the Electronic Shift 4WD System, and the
instrument panel control is moved to 4WD Low while the vehicle
is moving, the system will not engage and no damage will occur to
the 4WD system. Before 4WD Low can be engaged, the vehicle
must be at a complete stop with the brake pedal depressed and
the transmission in N (Neutral).
4H or 4L operation is not recommended on dry pavement. Doing
so could result in difficult disengagement of the transfer case,
damage to the transfer case, increased tire wear, decreased fuel
economy and difficulty turning.
Control-Trac automatic four-wheel drive system (if equipped)
Your 4x4 features the heavy-duty Control-Trac system which includes a
computer-operated transfer case. This unique system is interactive with
the road, continually monitoring and adjusting torque delivery to the
front and rear wheels to optimize vehicle control.
Positions of the Control-Trac system
The Control-Trac A4WD system
functions in three modes:
²A4WDposition delivers power to
the rear axle. If the rear wheels
lose traction, power will be
automatically delivered to the
front axle to maintain traction
throughout the slippery condition.
²4Hposition provides
mechanically locked four-wheel
drive power delivery to front and rear axles.
²4Lposition provides mechanically locked four-wheel drive when above
average power at reduced speeds is required.

²Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
²Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
²If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, Ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
²It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may loose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
²It often may be less risky to strike small inanimate objects, such as
highway reflectors, with minor damage to your vehicle rather than
attempt a sudden return to the pavement which could cause the
vehicle to slide sideways out of control or roll over. Remember, your
safety and the safety of others should be your primary concern.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
Do not rock the vehicle for more than a few minutes or damage to
the transmission and tires may occur or the engine may overheat.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.
Emergency maneuvers
²In an unavoidable emergency situation where a sudden sharp turn must
be made, remember to avoid ªover-drivingº your vehicle, i.e., turn the
steering wheel only as rapidly and as far as required to avoid the
emergency. Excessive steering will result in less vehicle control, not
more. Additionally, smooth variations of the accelerator and/or brake
pedal pressure should be utilized if changes in vehicle speed are called
for. Avoid abrupt steering, acceleration or braking. Use all available road
surface to return the vehicle to a safe direction of travel.
Driving

²In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
²If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or barking). Again,
avoid these abrupt inputs.
Parking
On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. Do not
leave the vehicle unattended with the transfer case in N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
4WD Systems (if equipped)
4WD (when you select the 4WD mode), uses all four wheels to power
itself. This increases traction, enabling you to drive over terrain and road
conditions that a conventional two-wheel drive vehicle can't.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance and specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentary clunk and ratcheting
sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Driving
171

Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Water intrusion into the transmission may damage the transmission.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.

system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
²Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
²Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
²GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
²GVWR (Gross Vehicle Weight Rating):Maximum permissable total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Safety
Certification Label on the driver's door pillar.
²GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Certification Label on the driver's door pillar.
²GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including occupants and cargo) and the loaded trailer.
²GCWR (Gross Combined Weight Rating):Maximum permissable
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer
²Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
Driving
177

determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
²Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle (including occupants and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
²Trailer Weight Range:Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Safety Certification Label, found on the driver's door pillar, lists
several important vehicle weight rating limitations. Before adding any
additional equipment, refer to these limitations. If you are adding weight
to the front of your vehicle, (potentially including weight added to the
cab), the weight added should not exceed the front axle reserve capacity
(FARC). Additional frontal weight may be added to the front axle reserve
capacity provided you limit your payload in other ways (i.e. restrict the
number of occupants or amount of cargo carried).
Always ensure that the weight of occupants, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both gross vehicle weight and front and rear gross
axle weight rating limits. Under no circumstance should these limitations
be exceeded.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.
