2008 DODGE RAM 5500 CHASSIS CAB oil level

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 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 as
required into the dipstick tube.Do not overfill.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 (21É C) (room tempera-
ture). If the fluid level is correctly established at room
temperature, it should be between the HOT (upper)reference holes when the transmission reaches 180É F (21É
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.
7. 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.

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.

EMISSION CONTROL SYSTEM MAINTENANCE
The ªScheduledº maintenance services, listed inbold
typein this section (Section 8) must be done at the times
or mileages specified to assure the continued proper
functioning of the emission control system. These, and all
other maintenance services included in this manual,
should be done to provide best vehicle performance and
reliability. More frequent maintenance may be needed for
vehicles in severe operating conditions such as dusty
areas and very short trip driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the emis-
sion control devices and systems on your vehicle may be
performed by any automotive repair establishment or
individual using any automotive part which has been
certified pursuant to U.S. EPA or, in the State of Califor-
nia, California Air Resources Board regulations.

CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
At Each Stop for Fuel
²Check the engine oil level about 30 minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when
the level is at or below the ADD or MIN mark.

²Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.

damage.
²Inspect the batteries and clean and tighten the termi-
nals as required.
²Check the fluid levels of coolant reservoir, transmis-
sion and transfer case (if equipped), add as needed.

tions of brake maintenance.
²Check Filter MinderŸ. Replace air cleaner filter
element if necessary.
²Check all lights and all other electrical items for correct
operation.
