2004 FORD F750 automatic transmission fluid

Engine compartment (with engine stopped)
Any leaks:Check for signs of fluid puddles, dripping fluid
on the ground under the engine or the
underside of the engine.
HVAC air inlet:Check for debris, leaves, etc. that may have
collected on the HVAC air inlet grille or inside
the exterior module as this may cause reduced
system performance.
HVAC fresh air filter
(if equipped):Periodically check the HVAC fresh air filter for
cleanliness.
Exercise great caution when working on vehicle equipped with
an automatic fan clutch. The fan starts in motion only after the
engine coolant reaches a predetermined temperature or the refrigerant
pressure (if equipped with air conditioning) reaches a predetermined
setting. The fan will start at these point with no advance warning.
Never reach near, or permit objects to protrude into, the fan blade
radius while the engine is running as this could result in vehicle
damage, personal injury or death.
Engine starting (with parking brake applied)
Safety/Emergency
equipment:Prior to entering the cab, verify that the
vehicle is equipped with spare electrical fuses
(if used), three red reflective triangles, a
properly charged and rated fire extinguisher
and wheel chocks. Walk around the vehicle
and check that all steps and grab handles,
inside and out as well as behind, are tight and
clean. Use extreme caution and a three-point
stance at all times. Check door latches for
positive closing, latching and locking.
Clutch/Gearshift:Depress the clutch (if equipped with a manual
transmission) and verify the transmission is in
neutral before turning on the starter. Keep the
pedal depressed until the engine reaches idling
speed.
Oil pressure builds:Make sure engine oil pressure is building to
normal operating range.

Engine starting (with parking brake applied)
Air brake check:Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor protection valve knob):
1. Check the air compressor or governor
cut-out pressure (approximately 305 kPa [120
psi]).
2. Cut-off the engine and turn the key back to
ON, without starting the engine.
3. Without the brake pedal applied, note the
air pressure drop for one minute. It should be
less than 5 kPa (2 psi) for single vehicle and 8
kPa (3 psi) for combination vehicles.
4. Depress and hold the brake pedal with 621
kPa (90 psi) or more and make sure there is
no more than a 8 kPa (3 psi) per minute leak.
For combination vehicles, no more than 10
kPa (4 psi) per minute.
5. Step on and off the brake pedal and check
for the warning light and chime to activate
between 163-193 kPa (64–76 psi).
6. Step on and off the brake pedal and make
sure the tractor protection and parking brake
knobs pop out between 138–310 kPa (20–45
psi)
7. Restart the engine, shift to a lower gear and
gently pull against the service and parking
brakes separately to make sure they hold.
Automatic
transmission fluid:With the engine idling (at normal operating
temperature) and the parking brake applied,
check the automatic transmission fluid. If fluid
needs to be added, place the transmission in
the appropriate gear as specified in the
transmission operator’s manual and refer to
Transmission fluidin theMaintenance and
specificationschapter.

TRANSMISSION
If your vehicle is equipped with an automatic transmission, have a
qualified technician regularly check the transmission’s neutral start
switch.
If the unit starts in gear and/or the neutral start switch is
defective, the vehicle may inadvertently move which could result
in property damage, personal injury or death.
Check the transmission fluid level and shift linkage for proper operation.

If the engine speed is above idle when a gear is selected using the
shifter, the vehicle will not move. To move the vehicle, the shifter must
be moved to re-select a gear after the engine speed returns to idle.
Note:For more information regarding the Allison MD-WT, refer to the
separate Allison MD-WT Operator’s Manual.
Torque lock
If your vehicle is parked on an incline and P (Park) is not properly
engaged (The parking brake is not applied before the transmission is
shifted into P [Park]), the weight of the vehicle may generate an
excessive amount of torque on the park pawl. In this situation, it may be
difficult to shift the transmission out of P (Park). Hold the brake pedal
down while shifting out of P (Park), then release the parking brake.
Allison MD (Medium Duty) push-button shifter
To shift the transmission into R
(Reverse) or D (Drive), depress the
brake pedal, then press R or D, then
release the brake pedal. To select a
lower range when in D (Drive),
press the down-arrow button. To
select a higher range when in D
(Drive), press the up-arrow button.
To place the transmission in N
(Neutral), press N.
Automatic transmission operating temperatures
Allison 2000/2400–The sump/fluid reservoir temperatures should not
exceed 120°C (250°F). The converter temperature should not exceed
144°C (300°F).
Power take-off (PTO) operation with an Allison automatic
transmission (except MD applications and vehicles equipped with
a Caterpillar 3126E engine)
The power take-off can be operated while the vehicle is standing or
moving.
To engage the PTO, apply the brakes and shift to any gear other than N
(Neutral) - this stops the rotation of the PTO drive gear in the
transmission - then engage the PTO.

•If the fluid temperature is at
approximately 20°C-49°C (68°F
- 120°F) (fluid cool or warm to
the touch), check the COLD side
of the dipstick. The fluid level
should be within the FULL range
•If the fluid level is below the ADD
line, add fluid in small amounts,
continuously checking the level until it reaches the proper level.
•If the fluid temperature is at
approximately 80°C - 110°C
(176°F - 230°F) (fluid too hot
to touch), check the HOT side of
the dipstick. The fluid level
should be within the FULL range.
•If the fluid level is below the ADD
line, add fluid in small amounts,
continuously checking the level until it reaches the proper level.
Note:The fluid level may also be checked by looking at the see-through
plastic reservoir. Make sure that the fluid is within the minimum and
maximum fluid range as marked on the reservoir.
A low fluid level may indicate a leak in the power steering system.
Inspect the power steering system and repair the leak. If necessary, see
your dealer or a qualified service technician.
