speeds will reduce fogging. Interior fogging on the
windshield can be quickly removed by selecting the
defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Recommended
Fluids and Genuine Parts for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation isencountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift into
NEUTRAL and depress the accelerator slightly for fast
idle operation to increase coolant flow and fan speed.
NOTE:On models equipped with Diesel engines, the
idle speed will automatically increase to 1000 rpm at
elevated coolant temperatures to improve engine cooling.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.

Overdrive Operation
The overdrive automatic transmission contains an elec-
tronically controlled fourth and fifth (if equipped) speed
(Overdrive). The transmission will automatically shift
from Drive to Overdrive if the following conditions are
present:
²the transmission selector is in Drive;
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.
NOTE:If the vehicle is started in extremely cold tem-
peratures, the transmission may not shift into Overdriveand 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 level. 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 TRANS TEMP light
may illuminate and the transmission may downshift out
of Overdrive until the transmission cools down. After
cooldown, the transmission will resume normal opera-
tion.
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).

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 tothe 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 Ð 5-Speed
NOTE:The parking brake should be engaged before
leaving the vehicle, especially on an incline.
Truck models with manual transmission are equipped
with a clutch interlocking ignition system. The clutch
pedal must be fully depressed to start the vehicle.
Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal.

Lubricant Selection NV-3500 (5-Speed Manual
Transmission Ð If Equipped)
This transmission is filled with manual transmission
fluid at the factory. This fluid does not require periodic
changing. If it is necessary to add or change fluid in this
transmission refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type. This is the only
lubricant recommended for use in the NV-3500 transmis-
sion.
Lubricant Selection NV-4500 (5-Speed Manual
Transmission Ð If Equipped)
This transmission does not require periodic changing. If
it becomes necessary to add or change the fluid in this
transmission, refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type.
Automatic Transmission
Fluid Level Check
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. Operation of the trans-
mission with an improper fluid level will greatly reduce
the life of the transmission and of the fluid. Check the
fluid level whenever the vehicle is serviced.
Fluid Level Check ± 45RFE/545RFE
Check the fluid level while the transmission is at normal
operating temperature 82ÉC (180ÉF). This occurs after at
least 15 miles (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
352 MAINTAINING YOUR VEHICLE

To check the automatic transmission fluid level properly,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake
pedal.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).
5. Remove the dipstick, wipe it clean and reinsert it until
seated.
6. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the ªHOTº
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that solid coating of oil is seen on
both sides of the dipstick. If the fluid is low, add asrequired into the dipstick tube.Do not overfill.After
adding any quantity of oil through the oil fill tube, wait
a minimum of two (2) minutes for the oil to fully drain
into the transmission before rechecking the fluid level.
NOTE:If it is necessary to check the transmissionbelow
the operating temperature, the fluid level should be
between the two ªCOLDº (lower) holes on the dipstick
with the fluid at approximately 70ÉF (21ÉC) (room tem-
perature). If the fluid level is correctly established at
room temperature, it should be between the ªHOTº
(upper) reference holes when the transmission reaches
180ÉF (82ÉC). Remember it is best to check the level at the
normal operating temperature.

Automatic Transmission Fluid and Filter Change
To obtain best performance and long life for automatic
transmissions, the manufacturer recommends that they
be given regular maintenance service by an Authorized
Dodge Dealer or Service Center.
It is important that proper lubricant is used in the
transmission. Refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type.
The fluid and filter(s) should be changed as specified in
the Maintenance Schedule (Section 8).
NOTE:If the transmission is disassembled for any
reason, the fluid and filter(s) should be changed.
Special Additives
The manufacturer strongly recommends against the ad-
dition of any additives to the transmission. Exception to
this policy is the use of special dyes to aid in detectingfluid leaks. The use of transmission sealers should be
avoided, since they may adversely affect seals.
Front Wheel Bearings
Front wheel bearings for all Dodge Ram Trucks are
sealed-for-life. They do not require greasing or seal
replacement. In some instances, these bearings will
ªpurgeº excess grease and the bearing will look slightly
wet. This is normal. Periodic inspection for excess play is
recommended.
Rear Wheel Bearings Ð Manufacturer's Axles
These bearings are normally considered permanently
lubricated. Cleaning and repacking is required only
when axle shafts are removed or in case of extreme water
or dust contamination.
