transmission Ram 3500 Chassis Cab 2018 Manual PDF

Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.

WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”. It
is important to maintain the transmission fluid at the
correct level using the recommended fluid. No chemical
flushes should be used in any transmission; only the
approved lubricant should be used.

SERVICING AND MAINTENANCE 387

CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder, and will require more frequent fluid and
filter changes. Refer to “Fluids And Lubricants” in
“Technical Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
The only exception to this policy is the use of special dyes
for diagnosing fluid leaks. Avoid using transmission seal-
ers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check
Check the fluid level when the engine is fully warmed up
and the transmission fluid is at normal operating tempera-
ture. Driving 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 — Procedure
It is best to check the fluid level when the transmission is at
normal operating temperature (170-180°F / 77-82°C for 66RFE
transmission, or 158–176°F / 70–80°C for AS66RC transmis-
sion). This normally occurs after at least 15 miles (25 km) of
driving. At normal operating temperature the fluid cannot be
held comfortably between the fingertips. You can read the
transmission sump temperature in the instrument cluster dis-
play (refer toInstrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information).
Use the following procedure to check the transmission
fluid level properly:
1. Monitor the transmission temperature using the instru- ment cluster display, and operate the vehicle as required
to reach the normal operating temperature. If the trans-
mission is not functioning properly, or the vehicle
cannot be driven, see the NOTE and CAUTION below
about checking the fluid level at colder temperatures.
388 SERVICING AND MAINTENANCE

2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60seconds, and leave the engine running for the rest of this
procedure.
4. Fully apply the parking brake and press the brake pedal.
5. Place the gear selector momentarily into each gear position (allowing time for the transmission to fully
engage in each position), ending with the transmission
in PARK.
6. Wipe the area around the dipstick clean to prevent dirt from entering the transmission.
7. Remove the dipstick, wipe it clean and reinsert it until seated.
8. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is only valid if there
is a solid coating of oil on both sides of the dipstick.
Note that the holes in the dipstick will be full of fluid if
the actual level is at or above the hole. The fluid level
should be between the “HOT” (upper) reference holes
on the dipstick at normal operating temperature. If the
fluid level is low, add fluid through the dipstick tube to
bring it to the proper level. Do not overfill.Use ONLY the specified fluid (see
Fluids, Lubricants, and Genuine
Parts for fluid specifications). After adding any quan-
tity of oil through the dipstick tube, wait a minimum of
two minutes for the oil to fully drain into the transmis-
sion before rechecking the fluid level.
NOTE: If it is necessary to check the transmission below
the operating temperature, the fluid level should be be-
tween the two “COLD” (lower) holes on the dipstick with
the fluid at 60-70°F / 16-21°C for 66RFE transmission, or
68-86°F / 20-30°C for AS66RC transmission. Only use the
COLD region of the dipstick as a rough reference when
setting the fluid level after a transmission service or fluid
change. Re-check the fluid level, and adjust as required,
once the transmission reaches normal operating tempera-
ture.
CAUTION!
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. Run the engine at idle, in PARK, to warm the
fluid.

9. Reinsert the dipstick. Check for leaks. Release the park-ing brake.
NOTE: To prevent dirt and water from entering the trans-
mission after checking or replenishing fluid, make sure that
the dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the dipstick
tube.
Fluid And Filter Changes
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.
In addition, change the fluid and filters if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For models with 9.25 in Front Axles and 11.5 in Rear Axles,
refer to “Fluids And Lubricants” in “Servicing And Main-
tenance” for further information. For normal service, peri-
odic fluid level checks are not required. When the vehicle is
serviced for other reasons, the exterior surfaces of the axle
assembly should be inspected. When checking the fluid level (4500/5500 only), the vehicle
should be in a level position. The fluid level should be ¼ in
± ¼ in (6.4 mm ± 6.4 mm) below the fill hole on the front
axle. The fluid level should be level with the bottom of the
fill hole on the rear axle.
Drain And Refill
On 4500/5500 vehicles, remove the lower bolt to drain the
axle fluid.
