2008 DODGE RAM 3500 CHASSIS CAB Owners Manual

Procedure For Checking Fluid Level
To properly check the automatic transmission fluid level,
the following procedure must be used:
1. The vehicle must be on level ground.
2. Operate the engine at idle speed for a minimum of 60
seconds and normal operating temperature.
3. Fully apply parking brake and press the brake pedal.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park). Make sure the
engine is running at idle speed.
5. Remove the dipstick and determine if the fluid is hot
or cold. Hot fluid is approximately 160É F - 175É F (70É C
± 82É C), Which is the normal operating temperature after
the vehicle has been driven at least 15 miles. The fluid can
not be comfortably held between the finger tips. Only usethe cold region on the dipstick as a rough reference when
doing initial oil level set after transmission rebuild or
transmission refill.
6. Wipe the dipstick clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on
both sides. The fluid level should be between the HOT
(upper) reference holes on the dipstick at normal operat-
ing temperature. Verify that a solid coating of oil is seen
on both sides of the dipstick. If the fluid is low, add
MopartA68SRCŸ Automatic Transmission Fluid as
required into the dipstick tube.Do not overfill. Never
use any ATF other than MopartAS68RCŸ Automatic
Transmission Fluid.After adding any quantity of oil
through the dipstick 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 transmission below
the operating temperature, the fluid level should be

between the two cold (lower) holes on the dipstick with
the fluid at approximately 70É F ± 85É F (20É C ± 30É C). If
the fluid level is correctly established at room tempera-
ture, it should be between the HOT (upper) reference
holes when the transmission reaches 160É F - 175É F (70É
C ± 82É C). Remember it is best to check the level at the
normal operating temperature.
CAUTION!
Be aware that if the fluid temperature is below 50É F
(10É C), it may not register on the dipstick. Do not add
fluid until the temperature is elevated enough to
produce an accurate reading. Never use any ATF
other than MopartAS68RCŸ Automatic Transmis-
sion Fluid.
8. Check for leaks. Release the Parking Brake.NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly reseated. It is
normal for the dipstick cap to spring back slightly from
its fully seated positions, as long as its seal remains
engaged in the dipstick tube.
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 the
transmission fluid is maintained at the correct level, and
that it be drained and refilled as specified.
It is important that proper lubricant is used in the
transmission. Refer to Fluids, Lubricants and Genuine
Parts for the correct lubricant type. A filter change should
be made at the time of the oil change.
450 MAINTAINING YOUR VEHICLE

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 should be changed, and the
bands adjusted (if equipped).
Special Additives
The manufacturer recommends against the addition of
any additives to the transmission. Exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. The use of transmission sealers should be avoided,
since they may adversely affect seals.
Front and Rear Wheel Bearings
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 willªpurgeº 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.

All vehicles built over 10,000 lbs. (4 535 kg) Gross Vehicle
Weight Rating and manufactured for sale and use in the
United States are required to comply with the Federal
Government's Exterior Noise Regulations. These vehicles
can be identified by the Noise Emission Control Label
located in the operator's compartment.Required Maintenance For Noise Control Systems
The following maintenance services must be performed
every 6 months or 6,000 miles (9 600 km) whichever
comes first, to assure proper operation of the noise
control systems. In addition, inspection and service
should be performed anytime a malfunction is observed
or suspected. Proper maintenance of the entire vehicle
will help the effectiveness of the noise control systems.
Exhaust System
Inspect the entire exhaust system for leaks and damaged
parts. Devices such as hangers, clamps, and U-bolts
should be tight and in good condition. Damaged compo-
nents, burned or blown out mufflers, burned or rusted
out exhaust pipes should be replaced according to the
procedures and specifications outlined in the appropriate
service manual.

Air Cleaner Assembly
Inspect air cleaner housing for proper assembly and fit.
Make certain that the air cleaner is properly positioned
and that the cover is tight. Check all hoses leading to the
air cleaner for tightness. The air filter element must also
be clean and serviced according to the instructions out-
lined in the Maintenance Schedule Section of this
manual.
Tampering With Noise Control System Prohibited
Federal law prohibits the following acts or the causing
thereof: (1) the removal or rendering inoperative by any
person, other than for purposes of maintenance, repair, or
replacement, of any device or element of design incorpo-
rated into any new vehicle for the purpose of noise
control prior to its sale or delivery to the ultimate
purchaser or while it is in use, or (2) the use of the vehicle
after such device or element of design has been removed
or rendered inoperative by any person.Among those acts presumed to constitute tampering are
the acts listed below.
²AIR CLEANER
þRemoval of the air cleaner.
þRemoval of the air cleaner filter element from the air
cleaner housing.
þRemoval of the air ducting.
²EXHAUST SYSTEM
