TRANSMISSION FLUID
Always dispose of used automotive fluids in a responsible manner.
Follow your community's standards for disposing of these types of fluids.
Call your recycling center to find out about recycling automotive fluids.
Automatic transmission fluid
Refer to your Allison Automatic Transmission Operator's Manual for
scheduled intervals for transmission fluid checks and changes. Your
transmission does not consume fluid. However, the fluid level should be
checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Transmission fluid level should be checked by your dealer or a qualified
service technician.
If you must add transmission fluid, make sure the correct type of fluid is
being used. The type of fluid used is indicated in your Allison Automatic
Transmission Operator's Manual.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Manual transmission fluid
Refer to your scheduled maintenance guide for transmission fluid level
checks and fluid change intervals.
Your manual transmission may be filled with an optional synthetic fluid
which allows the use of extended service intervals. A tag on the filler
plug will identify the use of the synthetic fluid.
Use only fluid that meets Ford specifications (refer toLubricant
specificationsin this chapter.
Use of a non-approved transmission fluid may cause internal
transmission component damage.
For location of the transmission filler plug, refer to your transmission
operator's manual orTransmission refill capacitiesin this chapter.
Check your transmission fluid level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into 1 (First) and turn the engine off.
3. Clean any dirt from around the filler plug.

4. Remove the filler plug and inspect the fluid level.
5. The fluid level should be up to the bottom of the filler plug opening.
6. If necessary, add enough fluid through the filler plug opening so that
the fluid level is at the bottom of the opening.
7. Clean and install the filler plug securely.
Drain and refill your transmission fluid using the following procedure:
1. Drain the transmission while the fluid is warm.
2. Park the vehicle on level ground.
3. Set the parking brake and shift into 1 (First) and turn the engine off.
4. Clean any dirt from around the filler and drain plugs.
5. Remove the filler and drain plugs and drain the fluid into a suitable
container. Dispose all used automotive fluids in a responsible manner
following your local authorized standards.
6. Clean and install the drain plug securely.
7. Add enough fluid through the filler plug opening so that the fluid level
is up to the bottom of the opening.
8. Clean and install the filler plug securely.
REAR AXLE LUBRICANT
Refer to your Scheduled Maintenance Guide for rear axle lubricant level
checks and lubricant change intervals.
Your rear axle may be filled with an optional synthetic lubricant which
allows the use of extended service intervals. A tag on the filler plug will
identify the use of the synthetic lubricant.
Use only a lubricant that meets Ford specifications (refer toLubricant
specificationsin thischapter).
Use of a non-approved rear axle lubricant may cause internal axle
component damage.
Check your rear axle lubricant level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
3. Clean any dirt from around the rear axle filler plug.
4. Remove the filler plug and inspect the lubricant level.

5. The lubricant level should be up to the bottom of the filler plug
opening.
6. If necessary, add enough lubricant through the filler plug opening so
that the lubricant level is at the bottom of the opening.
7. Clean and install the filler plug securely.
Drain and refill your rear axle lubricant using the following procedure:
1. Drain the rear axle while the lubricant is warm.
2. Park the vehicle on level ground.
3. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
4. Clean any dirt from around the rear axle filler and drain plugs.
5. Remove the filler and drain plugs and drain the lubricant into a
suitable container. Dispose all used automotive fluids in a responsible
manner following your local authorized standards.
6. Clean and install the drain plug securely.
7. Add enough lubricant through the filler plug opening so that the
lubricant level is up to the bottom of the opening.
8. Clean and install the filler plug securely.
AIR FILTER
When to service
Your vehicle is equipped with an air filter restriction gauge to determine
when to replace the air filter element. It is not possible to determine the
need for service by visually inspecting the air filter.
When the yellow indicator on the air
filter restriction indicator reaches
the red line, the air filter element
should be replaced.
Each time the air filter element is
replaced, reset the air filter
restriction indicator by pressing the
red button.

OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to assure proper retention.
EMISSIONS CONTROL SYSTEM
To assure the emissions control systems operate effectively, you should
have the services listed in the maintenance schedule performed at the
specified time and km/mileage intervals. You should avoid running out of
fuel or turning off the ignition while the vehicle is in motion, especially
at high speeds.
Because of high engine compartment and exhaust system
temperatures resulting from emissions equipment, do not park,
idle or operate your vehicle in dry grass or other dry ground cover
where the possibility of ground fire exists.
Do not make unauthorized modifications to the engine or vehicle.
Modifications causing increased amounts of unburned fuel to reach the
exhaust system can significantly increase the temperature of the engine
compartment and/or the exhaust system.
Avoid driving your vehicle if it does not operate properly. If the engine
diesels (more than five seconds of engine run-on after shut-off), misfires,
surges, stalls or backfires, see your dealer. Be alert for fluid leakage,
odor, smoke, loss of oil pressure, or charge indicator or over temperature
warning.
Do NOT use diesel fuel blended with waste oil in engines equipped with
a CATALYTIC CONVERTER-MUFFLER. Waste lube oil blending in fuel
will plug the CATALYTIC CONVERTER-MUFFLER, resulting in a
significant loss of engine power.
