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. The engine should be running at curb idle speed for a
minimum of 60 seconds.
3. Fully apply parking brake.
4. Place the gear selector briefly in each gear position
ending with the lever in N (Neutral).
5. Remove the dipstick and determine if the fluid is hot
or warm. Hot fluid is approximately 180°F (82°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. Warm is when
fluid is between 85° - 125°F (29° - 52°C).6. Wipe the dipstick clean and reinsert until seated.
Remove dipstick and note reading.
a. If the fluid is hot, the reading should be in the
crosshatched area marked “OK”.
b. If the fluid is warm, the reading should be between
the two holes. If the fluid level indicates low, add
sufficient fluid to bring to the proper level.
Fluid is added through the dipstick tube.
NOTE:To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
certain that the dipstick cap is properly seated.

Selection Of Lubricant
Refer to Fluids, Lubricants and Genuine Parts for the
correct lubricant type. It is important that the transmis-
sion fluid be maintained at the prescribed level using the
recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turers recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturers recommended fluid will result in
more frequent fluid and filter changes. Refer to
Fluids, Lubricants and Genuine Parts for correct
fluid type.
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 be adjusted periodically, the fluid main-
tained 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 band adjustment
and filter change should be made at the time of the oil
change.
The fluid and filter(s) should be changed and the bands
adjusted (if equipped) as specified in the Maintenance
Schedule (Section 8). Vehicles with a 5.9L Diesel Engine,
having severe usage should follow Maintenance Sched-
ule “B” of the Maintenance Schedule (Section 8).

Severe usage consists of:
•Off-the-highway operation;
•Trailer towing;
•Snow plow operation;
•Prolonged operation with heavy loading, especially in
hot weather.
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 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
“purge” excess grease and the bearing housing will look
slightly wet. This is normal.
•Periodic inspection for excess play is recommended.
•If a bearing assembly is accidentally separated when
servicing the brake rotors, it should be replaced.
Rear Wheel Bearings
Clean and repack when brake linings are replaced or
rotors resurfaced.

Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the batteries and clean and tighten the termi-
nals as required.
•Check the fluid levels of coolant reservoir, brake
master cylinder, and transmission and transfer case (if
equipped), add as needed.
•Check Filter Minder™. Replace air cleaner filter
element if necessary.
•Check all lights and all other electrical items for correct
operation.
•Drain water from the fuel filter.At Each Oil Change
•Change the engine oil filter.
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the U-Joints ( if equipped) and front suspen-
sion components.
