2006 FORD F250 SUPER DUTY transmission

Manual Shift On Stop (MSOS) 4x4 system (if equipped)
The 4WD system is engaged or
disengaged by rotating the control
for both front wheel hub locks from
the FREE or LOCK position, then
manually engaging or disengaging
the transfer case with the
floor-mounted shifter. For increased
fuel economy in 2WD, rotate both
hub locks to the FREE position.
• For proper operation, make
sure that each hub is fully
engaged and that both hub locks are set to the same position
(both set to LOCK or both set to FREE). To engage LOCK,
turn the hub locks completely clockwise; to disengage the hubs
(FREE), turn the hub locks completely counterclockwise.
• Some vehicles may be equipped with wheel ornaments that cover the
4x4 manual hub lock. These ornaments must be removed to access
the manual hub locks.
Electronic Shift On the Fly (ESOF) 4x4 system (if equipped)
If equipped with the electronic shift 4WD System, and the
instrument panel control is moved to 4X4 LOW (4WD Low) while
the vehicle is moving above 3 mph (5 km/h), the system will not
engage and no damage will occur to the 4WD system. Before 4X4
LOW (4WD Low) can be engaged, the vehicle speed must be
below 3 mph (5 km/h) with the brake pedal depressed and the
transmission in N (Neutral). This vehicle is equipped with a
non-synchronous low range gearset which will not allow the
transfer case to shift into 4X4 LOW (4WD Low) if vehicle speed
is above 3 mph (5 km/h). It is recommended that a shift to 4X4
LOW (4WD Low) is performed while the vehicle is moving at a
speed below 3 mph (5 km/h).
The 4WD system:
• provides 4x4 High engagement and disengagement while the vehicle is
moving.
• is operated by a rotary control located on the instrument panel that
allows you select 2WD, 4x4 High or 4x4 Low operation.
• uses auto-manual hub locks that can be engaged and disengaged
automatically based on the 4x4 mode selected.

3. Move the transfer case shift lever
through N (Neutral) directly to 4L
(4WD Low). If the shift lever does
not, or only partially moves to the
4L (4WD Low) position, perform a
shift with the transmission in N
(Neutral) and the vehicle rolling at
a speed below 3 mph (5 km/h). This
will ensure the transfer case is fully
engaged into 4L (4WD Low).
Shifting from 4L (4WD Low) to 4H (4WD High) or 2H (2WD High)
1. Bring the vehicle to a speed below 3 mph (5 km/h).
2. Place the gearshift lever in N (Neutral).
3. Move the transfer case shift lever
through N (Neutral) directly to 4H
(4WD High) or 2H (2WD High).
4. If the transfer case will not
engage into 4H (4WD High) or 2H
(2WD High), let the vehicle creep at
a speed above 1 mph (1.6 km/h),
then repeat steps 2 and 3.
5. If shifting to 2H (2WD High) with the vehicle at a complete stop,
disengage the locking hubs (optional) by rotating the hub lock control
from LOCK to FREE.
Using the N (Neutral) position
The transfer case neutral position overrides the transmission and
puts the vehicle in neutral regardless of transmission gearshift
lever position. The vehicle can move forward or backwards.
This position should only be used
when towing the vehicle. 2H

• Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
• Be 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
• If 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.
• It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
• It often may be less risky to strike small 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.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
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 35 mph (56 km/h). The tires may
fail and injure a passenger or bystander.
Refer to Transmission temperature gauge in the Instrument Cluster
chapter for transmission fluid temperature information.
Emergency maneuvers
• In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” 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 which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
• In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
• If 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 braking). 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 the N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.

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.
Driving through deep water may damage the transmission.
Refer to Transmission temperature gauge in the Instrument Cluster
chapter for transmission fluid temperature information.
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.

VEHICLE USED AS A STATIONARY POWER SOURCE
Auxiliary equipment called power take-off, or PTO, is often added to the
engine or transmission to operate utility equipment. Examples include a
wheel-lift for tow trucks, tools for construction and cranes. PTO
applications draw auxiliary horsepower from the powertrain, often while
the vehicle is stationary. In this condition, there is limited cooling air
flow through the radiator and around the vehicle that normally occurs
when a vehicle is moving. Depending on the level and duration of
auxiliary horsepower draw, vehicle conditions and surrounding
environmental conditions and other factors, this can contribute to
elevated transmission fluid temperatures and result in accelerated fluid
deterioration, fuel vapor over-pressurization, and other concerns. Ford
trucks are fully qualified for stationary PTO operation for 10 minutes or
less of continuous operation. For stationary PTO operation of extended
duration (beyond 10 minutes), diesel engine is recommended. Further
consult your aftermarket PTO installer, since the duration of operation
limit for the aftermarket PTO may be less than 10 minutes.
A more complete description of PTO operation is discussed in the Ford
Truck Body Builders Layout Book, found at
www.fleet.ford.com/truckbbas.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially when the depth is not known. Never drive through
water that is higher than the bottom of the hubs (for trucks) or the
bottom of the wheel rims (for cars). When driving through water,
traction or brake capability may be limited. Also, water may enter your
engine’s air intake and severely damage your engine or your vehicle may
stall. Driving through deep water where the transmission vent
tube is submerged may allow water into the transmission and
cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

Operating the vehicle with the snowplow attached
Do not use your vehicle for snow removal until it has been driven at
least 500 miles (800 km).
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature:
• If you are driving more than 15 miles (24 km) where outside air
temperatures are above freezing, then angle the plow blade to full left
or right to maximize airflow to the radiator.
• If you are driving less than 15 miles (24 km) at speeds up to 40 mph
(64 km/h) in cold weather you will not need to adjust blade position
Follow the severe duty schedule in your scheduled maintenance
information for engine oil and transmission fluid change intervals.
Snowplowing with your airbag-equipped vehicle
Your vehicle is equipped with a driver and passenger airbag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the airbag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag
supplemental restraint system (SRS) is provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible airbag deployment.
Do not attempt to service, repair, or modify the air bag
supplemental restraint system (SRS) or its fuses. See your Ford
or Lincoln Mercury dealer.
Additional equipment such as snowplow equipment may effect
the performance of the airbag sensors increasing the risk of
injury. Please refer to the Body Builders Layout Book for instructions
about the appropriate installation of additional equipment.

Transmission operation while plowing
Operate the vehicle with the automatic transmission gearshift lever in
the D (Overdrive) position and Tow/Haul OFF.
• Shift transfer case to 4x4 LOW (4WD Low) when plowing in small
areas at speeds below 5 mph (8 km/h).
• Shift transfer case to 4x4 HIGH (4WD High) when plowing larger
areas or light snow at higher speeds. Do not exceed 15 mph
(24 km/h).
• Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
• If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at normal operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.
Refer to Transmission temperature gauge in the Instrument Cluster
chapter for transmission fluid temperature information.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Removing the snowplow frame mount
A metal crossmember is included below the front bumper on Super Duty
vehicles called a “BlockerBeam”. Typical snowplow installations require
removal of this BlockerBeam to install the snowplow mounting hardware
to the vehicle frame.
The BlockerBeam must be re-installed if the snowplow
frame-mounting hardware is removed from the vehicle to ensure
proper airbag deployment in a crash.
