[DR15100(B F )03/95]
When you slow down or climb a steep hill,
always downshift before the engine starts to lose
power. Downshifting reduces the chance of
stalling and gives your vehicle better acceleration
to increase speed again.
*
[DR15200(B F )03/95]
When you drive down steep hills, downshifting
helps you keep a safe speed and helps prevent
unnecessary wear on the brakes.

[DR15300(B F )03/95]
When you come to a stop, do not downshift
through each gear. Disengage the clutch and use
the brake as necessary. Downshifting through
the gears decreases your vehicle's fuel economy.
*
[DR15400(B F )05/95]
RWARNING
Continued use of a damaged or worn
clutch, prolonged clutch slippage or
downshifting at excessive speeds can
result in a failure of the engine,
transmission or clutch components.
*
[DR15500(B F )03/91]
Transmission Function
*
[DR15600(B F )03/91]
Upshift at the speeds specified in the chart
available for your engine and transmission. All
forward gears are synchronized allowing you to
shift into them with your vehicle in motion. The
clutch pedal should be fully depressed when
shifting.
*
[DR15625(B F )04/94]
NOTE: Shifting during extremely low rpm's
can result in a momentary audible
rattle which disappears as vehicle
rpm's are increased. Shifting at higher
speeds will eliminate this sound.
*
[DR15700(B F )03/95]
Parking
*
[DR15800(B F )01/95]
To park your vehicle, apply the service brake
pedal, and shift into N (Neutral) while still
maintaining pressure on the service brake. Set
the parking brake fully. Shift into first and turn
off the ignition.
*
[DR15900(B F )05/95]
RWARNING
Do not park your vehicle in Neutral, it
may move unexpectedly and injure
someone. Use 1 (First) gear and set the
parking brake fully.

186 [DR15903(B F )05/95]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.
*
[DR15906(B F )05/95]
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.
*
[DR15915( ALL)01/95]
Steering Your Vehicle
%*
[DR15945( ALL)01/95]
Your vehicle comes with power steering. Power
steering uses energy from the engine to help
steer your vehicle.
%*
[DR15950( ALL)04/95]
If the amount of effort needed to steer your
vehicle changes at a constant vehicle speed, have
the power steering system checked. If the power
steering system breaks down (or if the engine is
turned off), you can steer the vehicle manually
but it takes more effort.
*
[DR15960( ALL)01/95]
Never hold the steering wheel to the extreme
right or left for more than five seconds if the
engine is running. This can damage the power
steering pump.
*
[DR15985( ALL)05/90]
NOTE: After any severe impact such as
striking large potholes, sliding into
curbs on icy roads, or a collision
involving the front end, observe the
steering wheel alignment. If the spokes
of the steering wheel seem to be in a
different position while going straight
down the road, have the front
suspension and steering checked for
possible damage.

Four-Wheel Drive (4WD)
System (If equipped)
*
[DR16130(B F )08/94]
When you select the 4WD mode, your light
truck uses all four wheels to power itself. This
increases traction, enabling you to drive your
4x4 over terrain and road conditions two-wheel
drive vehicles cannot.
*
[DR16160(B F )10/94]
Power is supplied to all four wheels through a
transfer case that allows you to select four-wheel
drive when necessary. Methods for engaging and
disengaging 4WD and low range will depend on
which system your vehicle has.
*
[DR16190(B F )01/95]
4x4 Systems Ð Lever Operated
*
[DR16220(B F )06/94]
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.
[DR16225(B F )05/95]
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.

[DR16310(B F )01/95]
Four-wheel drive operation (4H or 4L) on dry
pavement is not recommended. Operating the
vehicle in four-wheel drive on dry pavement
will increase tire wear, decrease fuel economy,
and make four-wheel drive disengagement
difficult for the transfer case.
*
[DR16340( F )06/93]
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.

Lever Operated System With Automatic
Locking Hubs
*
[DR16580(B F )06/94]
To shift from 2H to 4H:
*
[DR16610(B F )02/92]
Stop the vehicle and move the transfer case shift
lever straight back to the 4H position, the
automatic locking hubs will engage when the
vehicle is driven. When the automatic locking
hubs are engaged, shifts between 2H and 4H
may take place at any speed.
*
[DR16620(B F )02/92]
q
The automatic locking hubs may disengage in
2H if the vehicle's direction is momentarily
reversed, or the vehicle is allowed to roll
slightly in the opposite direction. If a
grinding noise occurs when shifting from 2H
to 4H while the vehicle is moving, one or
both of the automatic locking hubs have been
disengaged and the transfer case shift lever
should be switched back to the 2H position.
To shift back into 4H, stop the vehicle and
move the transfer case shift lever straight
back to the 4H position.
