AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
²Shift into ªPº (Park) only after the vehicle has
come to a complete stop.
²Shift into or out of ªRº (Reverse) only after the
vehicle has come to a complete stop and the engine
is at idle speed.
²Do not shift from ªRº (Reverse), ªPº (Park), or ªNº
(Neutral) into any forward gear when the engine is
above idle speed.
²Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
WARNING!
It is dangerous to shift the selector lever out of ªPº
(Park) or ªNº (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in ªRº (Reverse). You could lose control of
the vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your foot is firmly on the brake pedal.
Shift Lock Manual Override Ð If Equipped
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from ªPº (Park)
with the key in the ON position and the brake pedal
depressed. To operate the shift lock manual override,
perform the following steps:

Brake/Transmission Interlock System
This system prevents you from moving the gear shift out
of ªPº (Park) and into any gear unless the brake pedal is
pressed. Always depress thebrake pedal first,before
moving the gear selector out of ªPº (Park).
4±Speed Automatic Transmission
Shifting from ªDº (Drive) to ªPº (Park) or ªRº (Reverse)
(or from ªPº or ªRº to ªDº) should be done only after the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake when moving the
selector lever between these gears.

ªPº (Park)
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use ªPº (Park) while the vehicle is in
motion. Apply the parking brake when leaving the
vehicle in this range. Always apply parking brake first,
and then place the selector in ªPº (Park) position.
WARNING!
Never use ªPº (Park) position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
WARNING!
It is dangerous to shift the selector lever out of ªPº
(Park) or ªNº (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in ªRº (Reverse). You could lose control of
the vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your right foot is firmly on the brake pedal.
ªRº (Reverse)

ªNº (Neutral)
Shift into ªNº (Neutral) when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with selector lever in ªNº (Neutral) can
result in severe transmission damage. Refer to ªRecre-
ational Towingº in Section 5 and ªTowing a Disabled
Vehicleº in Section 6 of this manual.
ªDº (Drive)
For most city and highway driving.
ª2º (Second)
For moderate grades and to assist braking on dry pave-
ment or in mud and snow. Begins at a stop in low gear
with automatic upshift to 2nd gear. Will not shift to 3rd.ª1º (First)
For hard pulling at low speeds in mud, sand, snow, or on
steep grades. Begins and stays in low gear with no
upshift. Provides engine compression braking at low
speeds.
Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth speed (Overdrive). The trans-
mission will automatically shift from 3rd gear to Over-
drive if the following conditions are present:
²The transmission selector is in ªDº (Drive).

A Reset feature allows the vehicle to be driven to a dealer
for service without damaging the transmission. To reset
the transmission, perform the following procedure:
1. Stop the vehicle.
2. Move the selector lever to the ªPº (Park) position.
3. Turn off the engine; be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, and then restart the
engine.
5. Move the selector lever to the desired gear range.
If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists, ªPº
(Park), ªRº (Reverse), and ªNº (Neutral) will continue to
operate. Only Second gear range will operate in the ªDº
(Drive) position. Have the transmission checked at your
authorized dealer as soon as possible.MANUAL TRANSMISSION Ð IF EQUIPPED
Clutch Interlocking Ignition System
Vehicles equipped with a manual transmission are
equipped with a clutch interlock safety feature. The
clutch pedal must be fully depressed to allow cranking of
the engine.
To enhance off-road performance, 4-wheel drive models
equipped with a manual transmission will start with or
without pressing the clutch pedal when in 4-wheel drive
low range. The 4 LOW indicator light will illuminate
when the transfer case is in 4-wheel drive low range.

WARNING!
When parking your vehicle, always leave a manual
transmission in first gear and apply the parking
brake fully to guard against vehicle movement and
possible injury or damage. Never use any gear as a
substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
²Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, accelerated transmission wear may
result.
²Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
²Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
²Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
²When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
²Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
²During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
²Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.
290 STARTING AND OPERATING
Page 293 of 493

CAUTION!
²Do not attempt to make a shift while only the front wheels
or rear wheels are spinning. The MP1522 Command-Tract
transfer case is not equipped with a synchronizer and
therefore the speed of the front driveshaft and rear drive-
shaft must be equal for the shift to take place. Shifting
while only the front wheels or rear wheels are spinning can
cause damage to the transfer case.
²The 4WD Lock position and 4WD Low position are in-
tended for loose or slippery road surfaces only. Driving in
these positions on dry hard surfaced roads may cause
increased tire wear and damage to the driveline compo-
nents.
²When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 2WD posi-
tion or 4WD LOCK position at a given road speed. Take
care not to over-speed the engine and do not exceed 25 mph
(40 km/h).
²Proper operation of 4-wheel drive vehicles depends on tires
of equal size, type, and circumference on each wheel. Any
difference in tire size can cause damage to the transfer case.
WARNING!
²You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging
the parking brake. The transfer case Neutral (N)
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move despite the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
²Always engage the parking brake when powering
down the vehicle if the ªSERV 4WDº light is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
²Since 4-wheel drive provides improved traction,
there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road condi-
tions permit. You or others could be injured.

2WD to 4WD Lock
Move the 4WD Control Switch to the desired position.
Shifts between 2WD and 4WD LOCK can be done with
the vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage / disengage faster if
you momentarily release the accelerator pedal after mov-
ing the 4WD Control Switch. If the vehicle is stopped, the
ignition switch must be in the ON position with the
engine either OFF or RUNNING. This shift cannot be
completed if the ignition switch is in the ACC position.
NOTE:
²The 4-wheel drive system will not allow shifts be-
tween 2WD and 4WD LOCK if the rear wheels are
spinning (no traction). In this situation, the selected
position indicator light will flash and the original
position indicator light will remain ON. At this time,reduce speed and stop spinning the wheels to com-
plete the shift. There may be a delay up to 10 seconds
for the shift to complete after the wheels have stopped
spinning.
²Delayed shifting out of 4WD LOCK may be experi-
enced due to uneven tire wear, low tire pressure, or
excessive loading.
4WD Lock to 4WD Low
When shifting into or out of 4WD LOW, some gear noise
may be heard. This noise is normal and is not detrimental
to the vehicle or its occupants
Shifting can be performed with the vehicle rolling 2-3
mph (3-5 km/h) using the ªPreferred Procedureº or
completely stopped using the ªAlternate Procedure.º
296 STARTING AND OPERATING
Page 297 of 493

Preferred Procedure
1. With the engine RUNNING, slow the vehicle speed to
2-3 mph (3-5 km/h).
2. Shift the transmission into ªNº (Neutral) (automatic
transmission), or depress the clutch pedal (manual trans-
mission).
3. While still rolling, move the 4WD Control Switch to
the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission into gear (automatic
transmission), or release the clutch pedal (manual trans-
mission).
Alternate Procedure
1. Bring the vehicle to a complete stop.2. With the ignition switch in the ON position, and the
engine OFF or RUNNING, shift the transmission into
ªNº (Neutral) (automatic transmission), or depress the
clutch pedal (manual transmission).
3. Move the 4WD Control Switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission into gear (automatic
transmission), or release the clutch pedal (manual trans-
mission).
NOTE:
²Steps 1 and 2 in the ªPreferred Procedureº and the
ªAlternate Procedureº are requirements for shifting
the transfer case. If these requirements are not met
prior to attempting the shift or while the shift attempt
is in process, then the indicator light will flash, and the
current transfer case position will be maintained. To
retry a shift, move the 4WD Control Switch back to the

CAUTION!
²The 4WD Low position is intended for loose or
slippery road surfaces only. Driving in this posi-
tion on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline
components.
²When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD AUTO position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
²Proper operation of 4-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case.
WARNING!
²You or others could be injured if you leave the
vehicle unattended with the transfer case in the
Neutral (N) position without first fully engaging
the parking brake. The transfer case Neutral (N)
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move despite the transmission
position. The parking brake should always be
applied when the driver is not in the vehicle.
²Always engage the parking brake when powering
down the vehicle if the ªSERV 4WDº light is
illuminated. Not engaging the parking brake may
allow the vehicle to roll, which may cause personal
injury.
