Fluid Level Check — Eight-Speed Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis -
sion has no dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission malfunction, visit
an authorized dealer immediately to have the transmission
fluid level checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage. Fluid Level Check — Six-Speed Transmission
It is best to check the fluid level when the transmission is at
normal operating temperature (158-176°F / 70-80°C). 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 trans -
mission sump temperature in the instrument cluster screen
(refer to “Instrument Cluster Display” for further informa -
tion).
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.
2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60
seconds, and leave the engine running for the rest of this
procedure.
4. Fully apply the parking brake, and press the brake pedal.CAUTION!
Do not use chemical flushes in your transmission as the
chemicals can damage your transmission components.
Such damage is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to adjust
the fluid level accurately.

5. Place the gear selector momentarily into each gear posi -
tion (allowing time for the transmission to fully engage in
each position), ending with the transmission in PARK.
6. Remove the dipstick, wipe it clean and reinsert it until
seated.
7. 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 spec -
ified fluid (see "Fluids And Lubricants" for fluid specifica -
tions). After adding any quantity of oil through the
dipstick 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 oper -
ating temperature, the fluid level should be between the two
“COLD” (lower) holes on the dipstick with the fluid at
60-70°F / 16-21°C. Only use the COLD region of the dipstick as a rough reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid level, and
adjust as required, once the transmission reaches normal
operating temperature.
8. Reinsert the dipstick. Check for leaks. Release the parking
brake.
NOTE:
If it is necessary to check the transmission below the oper -
ating temperature, the fluid level should be between the two
COLD (lower) holes on the dipstick with the fluid at 68-86°F
/ 20-30°C. Only use the COLD region of the dipstick as a
rough reference when setting the fluid level after a transmis -
sion service or fluid change. Re-check the fluid level, and
adjust as required, once the transmission reaches normal
operating temperature. 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.

442 SERVICING AND MAINTENANCE
Fluid And Filter Changes — Eight-Speed Transmission
Under normal operating conditions, the fluid installed at the
factory will provide satisfactory lubrication for the life of the
vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contaminated
(with water, etc.), or if the transmission is disassembled for
any reason.
Fluid And Filter Changes — Six Speed Transmission
Refer to the “Maintenance Plan” for the proper maintenance
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 Mainte -
nance” for further information. For normal service, periodic
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, the vehicle should be in a
level position. The fluid level at room temperature should be
as follows:
3500 Front Axle: ¼ in ± ¼ in (6.4 mm ± 6.4 mm) below the
bottom of the fill hole.
3500 Rear Axle: ¼ in ± ¼ in (6.4 mm ± 6.4 mm) below the
bottom of the fill hole.
4500/5500 Front Axle: ¼ in +/- ¼ in (6.4 mm ± 6.4 mm)
below the bottom of the fill hole.
4500/5500 Rear Axle: 1/8 in +/- 1/8 in (3.2 mm +/- 3.2 mm)
below the bottom of the fill hole.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.
