2009 DODGE RAM 2500 DIESEL transmission fluid

WARNING!
Any work done to the vehicles electrical system, or
wiring, should be performed by a qualified automo-
tive technician, if done improperly it may cause
damage to the electrical system wiring and could
result in serious or fatal injury.Towing TipsBefore setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.Automatic TransmissionThe “DRIVE” range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, the
“TOW HAUL” or “OD/OFF” range should be selected.NOTE:
Using the “TOW HAUL” or “OD/OFF” range
while operating the vehicle under heavy operating con-
ditions will improve performance and extend transmis-
sion life by reducing excessive shifting and heat build up.
This action will also provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. Refer to the “Main-
tenance Schedule” in Section 8 for the proper mainte-
nance intervals.
NOTE: Check the automatic transmission fluid level
before towing.
Tow/Haul — If EquippedTo reduce potential for automatic transmission overheat-
ing, turn the “TOW HAUL OD/OFF” feature ON when
driving in hilly areas or shift the transmission to Drive
position 2 on more severe grades.

CAUTION!
•
Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•
Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and damage
the internal parts.
Recreational Towing Procedure — Electronic Shift
Transfer Case — If EquippedUse the following procedure to prepare your vehicle for
recreational towing:
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL before recre-
ational towing, to prevent damage to internal parts.1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Turn the ignition key to the ON position, but do not
start the engine.
4. Depress the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case NEUTRAL button for
four seconds.
7. After shift is completed and the NEUTRAL light
comes on, release the NEUTRAL button.
8. Start the engine.
9. Shift the transmission into REVERSE.
10. Release the brake pedal for five seconds and ensure
that there is no vehicle movement.400 STARTING AND OPERATING

•
The ignition key must be ON for a transfer case shift to
take place and for the position indicator lights to be
operable. If the key is not ON, the shift will not take
place and no position indicator lights will be on or
flashing.
•
Flashing Neutral position indicator light indicates that
shift requirements have not been met.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and 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.
CAUTION!
•
Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•
Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and fluid loss
will damage internal parts.

NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
2500/3500 Model Axles DO NOT REQUIREany limited
slip oil additive (friction modifiers).Transfer Case
Drain And RefillRefer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.Lubricant SelectionRefer to “Fluids, Lubricants, and Genuine Parts” in this
section for the correct fluid type.
Fluid Level CheckThis fluid level can be checked by removing the filler
plug. The fluid level should be to the bottom edge of the
filler plug hole with the vehicle in a level position.Automatic Transmission
Selection Of LubricantIt is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only the manufacturer ’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type. It is
important that the transmission fluid be maintained at
the prescribed level using the recommended fluid. No
chemical flushes should be used in any transmission;
only the approved lubricant may be used.

CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in this sec-
tion for correct fluid type.Fluid Level CheckIf your vehicle is equipped with a dipstick, use the
following procedure. If your vehicle has a capped dip-
stick tube, it is sealed and should not be tampered with.
Your authorized dealer has the proper tools to ensure that
the fluid level is set properly. The fluid level should be
checked when the engine is fully warmed up and thefluid in the transmission is at normal operating tempera-
ture. Operation of the transmission 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 – 545RFECheck the fluid level while the transmission is at normal
operating temperature 82°C (180°F). 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.
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 shift lever momentarily into each gear posi-
tion ending with the lever in 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 “HOT”
(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 as
required into the dipstick tube.Do not overfill.After
adding any quantity of oil through the oil fill tube, wait
a minimum of two 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 70°F (21°C) (room tem-
perature). If the fluid level is correctly established at
room temperature, it should be between the “HOT”
(upper) reference holes when the transmission reaches
180°F (82°C). Remember it is best to check the level at the
normal operating temperature.
CAUTION!
Be aware that if the fluid temperature is below 50°F
(10°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 parking brake.
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
