may be blank.
On MD 3000 series transmissions,operation may continue in order to
reach service assistance. The ECU may not respond to shift selector
requests, since operating limitations are being placed on the
transmission, i.e. upshifts and downshifts may be restricted. Direction
changes do not occur.
Refer to your transmission operator’s manual for more information.
Diesel exhaust fluid (diesel
engine only):Illuminates when the
diesel exhaust fluid level falls below
0.5 gallon (1.9L) in the 5 gallon
(19.0L) tank or 1 gallon (3.8L) in
the 9 gallon (34.0L) tank. Refill the
tank or, at a minimum, add at least
1 gallon (3.8L) to the 5 gallon
(19.0L) tank or 2 gallons (7.6L) to the 9 gallon (34.0L) tank.

TRANSMISSION FLUID
Automatic transmission fluid
Refer to yourAllison Automatic Transmission Operator’s Manualfor
scheduled transmission fluid check/change intervals. 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.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]). If your vehicle has been operated for
an extended period at high speeds, in city traffic or during hot weather,
the vehicle should be turned off for about 30 minutes to allow fluid to
cool before checking.
1. Drive the vehicle 20 miles (30 km) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.

4. Place the gearshift lever in N (Neutral) or P (Park) and leave the
engine running.
5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag.
6. Install the dipstick, making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level.
If you must add transmission fluid, refer to yourAllison Automatic
Transmission Operator’s Manualfor the correct fluid type.Use of a
non-approved automatic transmission fluid may cause internal
transmission component damage.
Fluid levels above the safe range may result in transmission failure; an
overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Eaton UltraShift (if equipped)
The Eaton UltraShift transmission is filled with synthetic fluid from the
factory with no scheduled fluid change intervals as this fluid is intended
to last the life of the transmission. However, the system should be
checked regularly to ensure that proper transmission fluid levels remain
constant. Refer to theEaton Driver Instructions Manualfor details.
Manual transmission fluid
Refer to theScheduled Maintenance Guidechapter for transmission
fluid level check/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 identifies the use of the synthetic fluid.
Only use fluid that meets manufacturer specifications; refer toLubricant
specificationsin this chapter.Use of a non-approved transmission
fluid may cause internal transmission component damage.
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.

Chemicals or additives not approved by Ford are not required for factory
recommended maintenance. In fact, Ford Motor Company recommends
against the use of such additive products unless specifically
recommended by Ford for a particular application.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
OWNER CHECKS AND SERVICES
Certain basic maintenance checks and inspections should be performed
by the owner or a service technician at the intervals indicated. Service
information and supporting specifications are provided in this owner’s
guide.
Any adverse condition should be brought to the attention of your dealer
or qualified service technician as soon as possible for the proper service
advice. The owner maintenance service checks are generally not covered
by warranties so you may be charged for labor, parts or fluids used.
