transmission FORD SUPER DUTY 2017 4.G Repair Manual

It is acceptable to have your two-wheel
drive vehicle towed with the front wheels
on the ground (without dollies) and the
rear wheels off the ground.
We recommend towing a four-wheel drive
vehicle with all wheels off the ground, such
as using a wheel lift and dollies or flatbed
equipment. However, it is acceptable to
use a wheel lift to raise the rear of your
vehicle so long as, depending on vehicle
configuration, you perform the following
before towing:
•
If your vehicle is equipped with a
manual-shift transfer case, make sure
the front wheel hub locks are in the
FREE position before towing.
• If your vehicle is equipped with an
electronic shift-on-the-fly transfer
case, make sure you turn the
four-wheel drive control to the
2H
position before towing.
Note: Towing an electronic shift-on-the-fly
four-wheel drive vehicle with the front
wheels on the ground without disengaging
the front hubs may cause damage to the
automatic transmission.
Note: Towing a two-wheel drive vehicle or
an electronic shift-on-the-fly four-wheel
drive vehicle with the rear wheels on the
ground for more than 50 miles (80 km) or
faster than 35 mph (56 km/h) may cause
damage to the automatic transmission.
Note: Using wheel lift equipment to tow a
dual rear wheel vehicle requires removing
an outer rear wheel before towing. TOWING POINTS WARNINGS
Using recovery hooks is dangerous
and should only be done by a person
familiar with proper vehicle recovery
safety practices. Improper use of recovery
hooks may cause hook failure or separation
from the vehicle and could result in serious
injury or death. Always slowly remove the slack from
the recovery strap prior to pulling.
Failure to do so can introduce
significantly higher loads which can cause
the recovery hooks to break off, or the
recovery strap to fail which can cause
serious injury or death. Never link two straps together with
a clevis pin. These heavy metal
objects could become projectiles if
the strap breaks and can cause serious
injury or death. Your vehicle comes equipped with
frame-mounted front recovery hooks.
These hooks should never have a load
applied to them greater than the gross
vehicle weight rating of your vehicle.
Before using recovery hooks:
•
Make sure all attaching points are
secure and capable of withstanding
the applied load.
• Never use chains, cables or tow straps
with metal hook ends.
• Only use recovery straps that have a
minimum breaking strength two to
three times the gross vehicle weight of
the stuck vehicle.
• Make sure the recovery strap is in good
condition and free of visible cuts, tears
or damage.

ENGINE OIL CHECK - 6.2L/6.8L
To check the engine oil level consistently
and accurately, do the following: 1. Make sure that your vehicle is on level
ground.
2. Run engine until it reaches normal operating temperature.
3. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.
5. Open the hood. See Opening and
Closing the Hood (page 320).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Under
Hood Overview (page 322).
7. Replace the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 324).
8. Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 422).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.

Adding Engine Oil
WARNING
Do not remove the filler cap when
the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.
Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Committee (ILSAC), comprised
of U.S. and Japanese automobile
manufacturers.
To top up the engine oil level do the
following:
1. Clean the area surrounding the engine
oil filler cap before you remove it.
2. Remove the engine oil filler cap. See Under Hood Overview (page 322).
Turn it counterclockwise and remove
it. 3. Add engine oil that meets Ford
specifications. See
Capacities and
Specifications (page 422). You may
have to use a funnel to pour the engine
oil into the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace the dipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately.

1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management (If Equipped) WARNING
To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not
be able to accelerate with full power until
the coolant temperature reduces. If you tow a trailer with your vehicle, the
engine may temporarily reach higher a
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display. You may notice a reduction in vehicle
speed caused by reduced engine power.
In order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to
drive your vehicle.
The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park
(P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
