[GF15800(F )01/96]
The lever operated transfer case can be placed
into four positions. The 2H position is the
two-wheel drive position in which power is
delivered only to the rear axle. The 4H position
provides four-wheel drive with power delivered
to the front and rear axles for increased traction.
The 4L position provides four-wheel drive with
power delivered to the front and rear axles
when the above average power is required at
reduced speeds. In the N (neutral) position, there
is no power delivered to either axle.
[GF15850(F )05/96]
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.
*
[GF15900(F )05/96]
RWARNING
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.

166 [GF16050(F )04/96]NOTE: All transfer cases on F-350 4x4 trucks
are equipped with an opening for a
power take-off (PTO). If this opening
is used for a transfer case mounted
PTO, additional transfer case lubricant
is required. Refer to the Refill
Capacities section for lubricant fill
requirements. Vehicles equipped with
an E4OD automatic transmission and a
7.3L diesel engine will require exhaust
modification for PTO clearance. For
vehicles equipped with an E4OD
automatic transmission: If a transfer
case mounted PTO is operated with the
transfer case shift lever in neutral, a
Vehicle Speed Sensor Self-test error
may be set in the Powertrain Control
Module (PCM) causing the
transmission to function abnormally,
and the Transmission Control Indicator
Light (TCIL) may flash on and off
repeatedly. Normal transmission
function should return when the
transfer case has been engaged and the
vehicle is driven. If the TCIL continues
to flash or the transmission continues
to operate abnormally contact your
Ford dealer as soon as possible.

[GF16650(F )01/96]
To shift from 4H to 2H:
[GF16700(F )04/96]
Move the transfer case shift lever straight
forward to the 2H position. This can be done at
any speed. To disengage the automatic locking
hubs, operate the vehicle in 2H in the opposite
direction for approximately 10 feet (3 meters).
*
[GF16750(F )05/96]
For example:
[GF16800(F )04/96]
If you were driving the vehicle forward in
4H, the automatic locking hubs will
disengage the next time the vehicle is driven
in reverse in 2H for approximately 10 feet (3
meters).
[GF16850(F )04/96]
If you were driving the vehicle in reverse in
4H, the automatic locking hubs will
disengage the next time the vehicle is driven
forward in 2H for approximately 10 feet (3
meters).
[GF16900(F )04/96]
Ð Operating in 2H with the hubs locked
increases fuel consumption, noise, vibration, and
wear. For prolonged 2H operation on dry
pavement, disengage the automatic locking hubs.
*
[GF16950(F )01/96]
To shift between 4H and 4L:
[GF17000(F )04/96]
Stop the vehicle and place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. Push the
transfer case shift knob down (toward the
ground) and at the same time pull or push the
lever straight forward or rearward (depending
on the desired position, 4H or 4L) in order to
shift the transfer case. This shift should be in
one continuous motion without pausing in the N
(neutral) position. Pausing in the neutral position
can result in gear clash and difficult shifting. If,
while shifting between 4H and 4L, the transfer

case gets stuck in the N (neutral) position or is
difficult to shift into either 4H or 4L, it may be
necessary to let the vehicle roll slightly and/or
turn off the engine (particularly on vehicles
equipped with automatic transmissions).
[GF17050(F )04/96]
To shift into and out of N (neutral)
[GF17100(F )04/96]
To shift into N (neutral), stop the vehicle and
engage the parking brake. Place the automatic
transmission into NEUTRAL or depress the
clutch on manual transmission vehicles. From
either the 4H or 4L position, push the transfer
case shift knob down (toward the ground) and
at the same time move the transfer case shift
lever to the N (neutral) position. The N (neutral)
position should only be used for vehicle towing
or transfer case mounted PTO use (transfer case
PTO opening available on F-350 as an option).
[GF17200(F )04/96]
NOTE: Dash mounted four wheel drive
indicator lights are off when your
vehicle is in neutral.

To shift from N (Neutral) to either 4H or 4L,
stop the vehicle and engage the parking brake.
Place the automatic transmission into NEUTRAL
or depress the clutch on manual transmission
vehicles. Push the transfer case knob down
(toward the ground) and at the same time move
the transfer case shift lever to the desired
position. If it is difficult to shift into either 4H or
4L, it may be necessary to let the vehicle roll
slightly and/or turn off the engine (particularly

% [GF19350(F )04/96]Driving Off Road with 4-Wheel
Drive
[GF19400(F )04/96]
Most vehicles with four-wheel drive are
especially equipped for driving on sand, snow,
mud, or rough terrain and have operating
characteristics that are somewhat different from
conventional vehicles, both off and on the road.
The driving tips below will help you learn to
use four-wheel drive.
[GF19450(F )04/96]
q
Do not use 4WD LOW on dry, hard-surfaced
roads.
*
[GF19500(F )01/96]
q
Special maintenance procedures are necessary
after operating with drive components in
water.
*
[GF19550(F )01/96]
q
Manual locking hubs must be in LOCK
position before shifting into four-wheel drive.
[GF19600(F )04/96]
When using four-wheel drive, maintain steering
wheel control at all times, especially in rough
terrain. Since sudden changes in terrain can
result in abrupt steering wheel motion, make
sure you grip the steering wheel rim from the
outside. Do not grip the spokes.

[GF19650(F )01/96]
Drive cautiously to avoid vehicle damage from
concealed objects such as rocks and stumps.
Know the terrain or examine maps of the area in
question before driving. Map out your route
beforehand. To maintain steering and braking
control of your vehicle, you must have all four
tires on the ground, and they must be rolling,
not sliding or spinning.
[GF19700(F )04/96]
Transmission upshift in 4x4 with transfer case in
4L may be quite firm due to large total gear
reduction. This condition is normal.
*
[GF19750(F )01/96]
Sand
*
[GF19800(F )01/96]
When driving over sand, try to keep all four
wheels of the vehicle on the most solid area of
the trail. Do not reduce the tire pressures but
shift to a lower gear and drive steadily through
the terrain. Apply accelerator slowly and avoid
spinning the wheels.
*
[GF19850(F )01/96]
Mud and Water
*
[GF19900(F )01/96]
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.
*
[GF19950(F )01/96]
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.
*
[GF20000(F )01/96]
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance which could damage drive
components.
*
[GF20050(F )03/96]
NOTE: If the transmission and transfer case is
submerged in water, their fluids should
be checked and changed, if necessary.

Trailer Towing
*
[GF20772(FM)03/96]
All vehicles may tow a Class I trailer provided
the Gross Combined Weight (GCW) is less than
or equal to the GVWR shown on the Safety
Compliance Certification Label. For heavier
trailer applications, refer to the towing
information found later in this chapter.
*
[GF20775(FM)01/96]
Towing a trailer puts additional loads on your
vehicle's engine, transmission, axle, brakes, tires
and suspension. For your safety and for the
good of your vehicle, use the right equipment
for the type of trailer you tow.
[GF20780(F )01/96]
If your trailer is equipped with electric brakes,
auxiliary battery, or back-up lamps, the optional
7 wire trailer towing electrical hook-up will be
required on the vehicle.
