TRANSMISSION SHIFTING
Four-Speed Overdrive Automatic Transmission Ð
If Equipped
The gear shift selector display, located in the instrument
panel cluster, indicates the transmission gear range (the
selector is illuminated for night driving). The selector
lever is mounted on the right side of the steering column.
You must depress the brake pedal, to pull the selector
lever out of park (P) position (Brake Interlock System). To
drive, move the selector lever from Park or Neutral to the
desired drive position. Pull the selector lever toward you
when shifting into Reverse, Second, First or Park, or
when shifting out of Park.
Gear Ranges
DO NOT race the engine when shifting from Park or
Neutral position into another gear range.
ªPº Park
This gear position supplements the parking brake by
locking the transmission. The engine can be started in
this range. Never use Park while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range. Always apply parking brake first, then place the
selector in Park position. On 4-wheel drive vehicles be
sure that the transfer case is in a drive position!
WARNING!
Your vehicle could move and injure you and others if
it is not completely in P (Park). Check by trying to
move the gearshift lever back and forth without first
pulling it toward you after you have set it in P. Make
sure it is in Park before leaving the vehicle.

ª1º First
Use this position for driving up very steep hills and for
engine braking at low speeds 20 mph (32 km/h) or less
when going downhill. To prevent excessive engine speed,
do not exceed 25 mph (40 km/h) in this range.
NOTE:Use caution when operating a heavily loaded
vehicle in ª2º Second or ª1º First gear selections in high
ambients as torque converter slip can impose significant
additional heat load on the cooling system.
WARNING!
Never use Park position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
Overdrive Operation
The four-speed overdrive automatic transmission con-
tains an electronically controlled fourth speed (Over-
drive). The transmission will automatically shift from
Drive to Overdrive if the following conditions are
present:
²the transmission selector is in Drive;
220 STARTING AND OPERATING
Page 221 of 426
²the engine coolant has reached normal operating tem-
perature;
²vehicle speed is above approximately 30 mph (48
km/h);
²the ªTOW/HAULº switch has not been activated;
²transmission has reached normal operating tempera-
ture.
The transmission will downshift from Overdrive to Drive
if the accelerator pedal is fully depressed at vehicle
speeds above approximately 35 mph (56 km/h).
Overdrive can be locked out by pressing the ªTOW/
HAULº button located on the selector lever. The ªTOW/
HAULº light will illuminate in the instrument cluster to
indicate that the switch has been activated. Pressing the
switch a second time restores the Overdrive function. If
the ªTOW/HAULº feature is desired, theªTOW/HAULº
button must be pressed each time the engine is started.NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdrive
and will automatically select the most desirable gear for
operation at this temperature. Normal operation will
resume when the transmission fluid temperature has
risen to a suitable temperature. Refer also to the Note
under torque converter clutch, later in this section.
If the transmission temperature gets extremely hot, the
transmission will automatically select the most desirable
gear for operation at this temperature. If the transmission
temperature becomes hot enough the ªTOW/HAULº
and/or TRANS TEMP light(s) may illuminate and the
transmission may downshift out of Overdrive until the
transmission cools down. After cooldown, the transmis-
sion will resume normal operation.
When To Lock Out Overdrive
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent 4±3±4 transmission shifting

occurs, press the ªTOW/HAULº button. This will im-
prove performance and reduce the potential for transmis-
sion overheating or failure due to excessive shifting.
Torque Converter Clutch
A feature, designed to improve fuel economy, has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
high gear. When the vehicle speed drops or during
acceleration when the transmission downshifts to second
gear, the clutch automatically disengages.
NOTE:The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1-3 miles (1.6 ± 4.8 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.Pressing the ªTOW/HAULº button, when the transmis-
sion is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of overdrive.
NOTE:If the vehicle has not been driven in several
days, the first few seconds of operation after shifting the
transmission into gear may seem sluggish. This is due to
the fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque converter
will refill within five seconds of shifting from Park into
any other gear position.
Manual Transmission ± 5±Speed (NV- 4500) Ð If
Equipped
NOTE:The parking brake should be engaged before
leaving the vehicle, especially on an incline.

Shifting Procedure - Manually Shifted Transfer
Case
2H,4H
Shifting between 2H and 4H can be made with the
vehicle stopped or in motion. If the vehicle is in motion,
shifts can be made up to 55 mph (88 km/h). With thevehicle in motion, the transfer case will engage / disen-
gage faster if you momentarily release the accelerator
pedal after completing the shift. Apply a constant force
when shifting the transfer case lever.
2H or 4H,4L
With the vehicle rolling at 2 to 3 mph (3 to 5 km/h), shift
an automatic transmission to N (Neutral) or depress the
clutch on a manual transmission. While the vehicle is
coasting at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not pause in
transfer case N (Neutral).
NOTE:Pausing in transfer case N (Neutral) in vehicles
equipped with an automatic transmission may require
shutting the engine OFF to avoid gear clash while
completing the shift. If difficulty occurs, shift automatic
transmission to N (Neutral), hold foot on brake, and turn
engine OFF. Make shift to the desired mode.

WARNING!
²Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also be certain to leave an automatic
transmission in Park, a manual transmission in
Reverse or first gear. Failure to do so may allow
the vehicle to roll and cause damage or injury.
²Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don't leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
²Be sure the parking brake is fully disengaged before
driving, failure to do so can lead to brake problems
due to excessive heating of the rear brakes.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic systems lose normal
capability, the remaining system will still function with
some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application,
greater pedal force required to slow or stop, and activa-
tion of the BRAKE warning lamp and the ABS lamp (if
equipped) during brake use.

Automatic Transmission Oil Temperature Warning
Light
All vehicles with heavy duty transmission oil cooling are
equipped with a transmission sump oil temperature
sensor and warning light. If elevated transmission tem-
peratures are encountered, the engine controller will
select the most desirable gear until the transmission
temperatures are reduced. If transmission oil tempera-
tures continue to rise, a warning light located in theinstrument cluster will illuminate. If this should occur,
stop the vehicle, shift to Neutral, and run the engine at
idle or faster until the light goes off.
Towing With An Automatic Transmission
Vehicles equipped with an automatic transmission may
shift into and out of Overdrive, or a lower gear, when
driving in hilly areas, when heavily loaded, or when
towing into heavy winds.
When this condition occurs, press the ªTOW/HAULº
button or shift into a lower gear to prevent excessive
transmission wear and/or overheating, and to provide
better engine braking.
NOTE:Do not exceed the following RPM while manu-
ally downshifting:
²5.9L Diesel Engines 3200 RPM.

SNOWPLOW
Snowplow Prep Packages are available as a factory
installed option. These packages include components
necessary to equip your vehicle with a snowplow.
NOTE:Before installation of a snowplow it is highly
recommended that the owner / installer obtain and
follow the recommendations contained within the Dodge
2004 BODY BUILDER'S GUIDE. See your dealer, installer
or snowplow manufacture for this information. There are
unique electrical systems that must be connected to
properly assure operator safety and prevent overloading
vehicle systems that would void the vehicle warranty.
WARNING!
Attaching a snowplow to this vehicle could ad-
versely affect performance of the airbag system in an
accident. Do not expect that the airbag will perform
as described earlier in this manual
CAUTION!
The ªLamp Outº indicator could illuminate if exte-
rior lamps are not properly installed.
