2007 DODGE RAM 2500 DIESEL automatic transmission

Lubricant Selection for 6-Speed Manual
Transmission — If Equipped
If it becomes necessary to add fluid or change the fluid,
be sure to use the same lubricant or equivalent. Refer to
Fluids, Lubricants and Genuine Parts for the correct
lubricant 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.
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.
