6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir. Refer toMaintenance product
specifications and capacitiesin this chapter for the proper fluid type.
BRAKE FLUID
•E-150/E-350 Single Rear Wheel
•E-350/E-450 Dual Rear Wheel
The fluid level will drop slowly as the brakes wear, and will rise when the
brake components are replaced. Fluid levels between the MIN and MAX
lines are within the normal operating range; there is no need to add
fluid. If the fluid levels are outside of the normal operating range, the
performance of the system could be compromised; seek service from
your authorized dealer immediately.
DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
Your vehicle may be equipped with universal joints that require
lubrication. Refer to thescheduled maintenance informationfor
maintenance intervals. If the original universal joints are replaced with
universal joints equipped with grease fittings, lubrication will also be
necessary.

TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to yourscheduled maintenance informationfor scheduled
intervals for 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.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 20 miles [30 km]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, 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. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated area for normal operating temperature or ambient
temperature.

Low fluid level
Do not drive the vehicle if the fluid level is at the bottom of the dipstick
and the ambient temperature is above 50°F (10°C).
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 150°F-170°F (66°C-77°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
You can check the fluid without driving if the ambient temperature is
above 50°F (10°C). However, if fluid is added at this time, an overfill
condition could result when the vehicle reaches normal operating
temperature.

The transmission fluid should be in this range if at normal operating
temperature (150°F-170°F [66°C-77°C]).

High fluid level
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.
High fluid levels can be caused by an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick. Refer toMaintenance
product specifications and capacitiesin this chapter.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint (250 ml) increments through the filler
tube until the level is correct.

If an overfill occurs, excess fluid should be removed by an authorized
dealer.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/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.

Automatic transmission fluid filter
The Torqshift automatic
transmission is equipped with a
serviceable transmission fluid filter
located inside the transmission
bottom pan.
Refer toscheduled maintenance
informationfor service intervals for
automatic transmission fluid and
transmission filter.
For transmission filter maintenance,
see your authorized dealer.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the air filter element
listed. Refer toMotorcraftpart numbersin this chapter.
WARNING:To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is running.

Changing the air filter element
1. Disconnect the fresh air inlet tube
from the radiator support.
2. Open the clamp that secures the
two halves of the air filter housing
together.
3. Carefully separate the two halves
of the air filter housing.
4. Remove the air filter element
from the housing.
5. Install a new air filter element. Be careful not to crimp the filter
element edges between the air filter housing. This could cause filter
damage and allow unfiltered air to enter the engine if not properly
seated.
6. Replace the two halves of the air filter housing and secure the clamp.
7. Connect the fresh air inlet tube to the radiator support.
Note:Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
