2008 FORD F350 transmission

3 (Third)
Transmission starts and operates in third gear only.
Used for improved traction on slippery roads. Selecting 3 (Third)
provides engine braking.
2 (Second)
Use 2 (Second) to start-up on slippery roads or to provide additional
engine braking on downgrades.
1 (First)
•Provides maximum engine braking.
•Allows upshifts by moving gearshift lever.
•The transmission will not downshift into 1 (First) at high speeds; it
will downshift to a lower gear and then shift into 1 (First) when the
vehicle reaches slower speeds.
Forced downshifts
•Allowed in D (Overdrive) or D (Drive).
•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
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 minute or damage to the
transmission and tires may occur, or the engine may overheat.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fully depressed.

To start the vehicle:
1. Make sure the parking brake is fully set.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.
3. Start the engine.
4. Press the brake pedal and move the gearshift lever to the desired
gear; 1 (First) or R (Reverse).
5. Release the parking brake, then slowly release the clutch pedal while
slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully depressed to the floor.
Failure to fully depress the clutch pedal to the floor may cause increased
shift efforts, prematurely wear transmission components or damage the
transmission. Make sure the floor mat is properly positioned so it doesn’t
interfere with the full extension of the clutch pedal.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Recommended shift speeds
Do not overspeed the engine when going downhill or steep grades. If
equipped, use the tachometer and do not allow engine speed to exceed
the redline area. Operating the engine beyond the recommended speeds
can cause severe engine damage.
Shift according to the following shift speed charts:

Reverse
1. Make sure that your vehicle is at a complete stop before you shift into
R (Reverse). Failure to do so may damage the transmission.
2. Move the gearshift lever into the neutral position and wait at least
three seconds before shifting into R (Reverse).
•The gearshift lever can only be moved into R (Reverse) by moving it
from left of 3 (Third) and 4 (Fourth) before shifting into R (Reverse).
This is a lockout feature that protects the transmission from
accidentally being shifted into R (Reverse) from D (Overdrive).
Parking your vehicle
1. Apply the brake and shift into the neutral position.
2. Fully apply the parking brake, then shift into 1 (First).
3. Turn the ignition off.
Do not park your vehicle in Neutral, it may move unexpectedly
and injure someone. Use 1 (First) gear and set the parking brake
fully.

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 while the vehicle
is moving above 5 mph (8 km/h), the system will not engage and
no damage will occur to the 4WD system. Before 4X4 LOW can be
engaged, the vehicle speed must be below 5 mph (8 km/h) with
the brake pedal depressed and the transmission in N (Neutral). If
your vehicle is equipped with a manual transmission, the clutch
pedal also must be depressed.This vehicle is equipped with a
non-synchronous low range gearset which will not allow the
transfer case to shift into 4X4 LOW if vehicle speed is above
5 mph (8 km/h). It is recommended that a shift to 4X4 LOW is
performed while the vehicle is rolling at a speed below 5 mph
(8 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.

Shifting from 4H (4x4 High) to 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below 5 mph (8 km/h).
2. Place the gearshift lever in N (Neutral). If the vehicle is equipped with
a manual transmission, also depress the clutch pedal.
3. Move the transfer case shift lever
through N (Neutral) directly to 4L
(4x4 Low).
4. If the shift lever does not, or only
partially moves to the 4L (4x4 Low)
position, perform a shift with the
transmission in N (Neutral) (or
clutch pedal depressed) and the
vehicle rolling at a speed below 5 mph (8 km/h). This will ensure the
transfer case is fully engaged into 4L (4x4 Low).
Shifting from 4L (4x4 Low) to 4H (4x4 High) or 2H (2WD)
1. Bring the vehicle to a stop or a speed below 5 mph (8 km/h).
2. Place the gearshift lever in N (Neutral). If the vehicle is equipped with
a manual transmission, also depress the clutch pedal.
3. Move the transfer case shift lever
through N (Neutral) directly to 4H
(4x4 High) or 2H (2WD).
4. If the transfer casewill not
engage into 4H (4x4 High) or 2H
(2WD), perform a shift with the
transmission in N (Neutral) (or
clutch pedal depressed) and the
vehicle rolling at a speed below 5 mph (8 km/h).
5. If shifting to 2H (2WD) with the vehicle at a complete stop, disengage
the locking hubs (optional) by rotating the hub lock control from LOCK

•Do not shift into 4x4 HIGH with the rear wheels slipping.
Shifting from 4x4 HIGH to 2WD
Rotate the 4x4 control to 2WD at
any forward speed. Disengagement
of the transfer case and front hubs
may be delayed due to torque bind
which is caused by driving on dry
hard surfaces or performing tight
turns while using the 4x4 system.
•Yo udo notneed to operate the vehicle in R (Reverse) to disengage
your front hubs, but it will eliminate any torque bind and allow the
system to immediately disengage.
Shifting from 4x4 HIGH to 4x4 LOW
1. Bring the vehicle to a complete stop.
2. Place the gearshift in N (Neutral). If the vehicle is equipped with a
manual transmission, also depress the clutch pedal.

LOW position.
4. Hold the shift conditions until the
4x4 LOW indicator light illuminates.
5. If the 4x4 LOW indicator light
does notilluminate within 15
seconds, allow the vehicle to move
at a speed below 5 mph (8 km/h),
then repeat steps 2 through 5 while
the vehicle is rolling before
reporting any shift concerns to your authorized dealer.
Shifting from 4x4 LOW to 4x4 HIGH or 2WD

Basic operating principles
•Do not use 4WD on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4WD modes are only intended for consistently slippery or loose
surfaces.
•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 arenot
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.
