2015 FORD F750 Transmission

Low Fluid Level
Do not drive your vehicle if there is
no indication of fluid on the dipstick
and the ambient temperature is
above 50°F (10°C).
Correct Fluid Level
Check the fluid at normal operating
temperature, 196°F-216°F
(91°C-102°C), on a level surface.
The fluid reaches normal operating
temperature after approximately 20 miles (30 kilometers) of driving.
High Fluid Level
Fluid levels above the safe range
may result in transmission failure.
An overfill condition of transmission
fluid may cause shift or engagement
concerns and possible damage.
Overheating conditions can cause
high fluid levels.
Adjusting Automatic Transmission Fluid Levels
Note:Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
Before adding any fluid, make sure the correct type is used. The dipstick
handle normally indicates which type of fluid to use. You can also find
the fluid specification in theCapacities and Specificationschapter.
If necessary, add fluid in 0.5 pint (250 milliliters) increments through the
filler tube until the level is correct.

If an overfill occurs, excess fluid
should be removed by a qualified
technician.
Note:An overfill condition of transmission fluid may cause shift or
engagement concerns or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
Manual Transmissions
Note:Use of a non-approved transmission fluid may cause internal
transmission component damage.
See theScheduled Maintenancechapter for scheduled intervals for
fluid checks and changes.
Your manual transmission may have an optional synthetic fluid that
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. SeeTechnical
specificationsin theCapacities and Specificationschapter.
Checking Fluid Level
1. Park your vehicle on level ground.
2. Set the parking brake, shift into first gear and turn the engine off.
3. Clean any dirt from around the filler plug.
4. Remove the filler plug and inspect the fluid level. The fluid level
should be at the bottom of the filler plug opening.
5. Add fluid, if necessary, through the filler plug opening.

POWER STEERING FLUID CHECK
Note:To avoid damage to the power steering system, do not operate
your vehicle with a low power steering fluid level.

Note:If adding fluid is necessary, use only the appropriate fluid. See the
Capacities and Specificationschapter. A low fluid level may indicate a
leak in the power steering system. Inspect the power steering system
and repair the leak or see an authorized dealer or a qualified technician
for service. See theScheduled Maintenancechapter for the
recommended service intervals.
Check the fluid level when it is at ambient temperature, 20°F–80°F
(-7°C–25°C):
1. Set the parking brake, and then start the engine.
2. Shift into positionNorP(if equipped) (automatic transmission) or
first gear (manual transmission) and turn the engine off.
3. Open the hood.
4. Clean the top of the power steering fluid reservoir.
5. Remove the dipstick from the reservoir and wipe the dipstick clean.
6. Reinstall the dipstick. Remove it again and check the fluid level.
Check the MAX. COLD side of the
dipstick if the fluid is cool or warm
to the touch (approximately
68°F-120°F [20°C-49°C]). The fluid
level should be within the FULL
range. If necessary, add fluid in
small amounts, continuously
checking the level, until it reaches
the proper level.
Check the MAX. HOT side of the
dipstick if the fluid is too hot to
touch (approximately 176°F–230°F
[80°C-110°C]). The fluid level
should be within the FULL range. If
necessary, add fluid in small
amounts, continuously checking the
level, until it reaches the proper
level.
When you install the dipstick, make sure to seat it and tighten it
securely.
You can also check the fluid level 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.

Your vehicle is equipped with two or three maintenance-free batteries
mounted in a covered tray located on the left frame rail. The covered
battery tray, depending upon application, may also have one or two steps
attached.
Covered battery tray shown
(battery tray with steps
similar).Pull up on the two rubber
straps on the battery cover and
move them to the side of the
battery in order to remove the lid.
Battery tray with cover
removed.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make sure you tightly fasten the battery cables to the battery
terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
If you plan to store your vehicle for an extended period, disconnect the
negative battery cable. This minimizes the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40 amp inline fuse located on the battery cable above the
battery.
Because a computer electronically controls your vehicle’s engine, battery
power controls some conditions. When you disconnect the battery or
install a new battery, the engine must relearn its idle and fuel trim
strategy for optimum driveability and performance. To begin this process:
1. With your vehicle at a complete stop, set the parking brake.
2. Put the gearshift in positionP(automatic transmission) or neutral
(manual transmission), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.

4. Allow the engine to idle for at least one minute.
5. Turn on the air conditioning and allow the engine to idle for at least
one minute.
6. Release the parking brake. With your foot on the brake pedal and
with the air conditioning on, put the transmission in positionP
(automatic transmission) or neutral (manual transmission) and allow
the engine to idle for at least one minute.Note:Not allowing the
engine to relearn the idle trim may adversely affect the idle quality of
your vehicle until the engine eventually relearns the idle trim.
7. Drive your vehicle to complete the relearning process.
If you disconnect the battery or install a new battery, you have to reset
the clock and radio settings after reconnecting the battery.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center to
find out more about recycling
automotive batteries.
CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
