Fluid levels above the safe range may
result in transmission failure. An overfill
condition of transmission fluid may cause
shift and engagement concerns, and
possible damage.
High fluid levels can be caused by an
overheating condition.
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 type of fluid used
is normally indicated on:
• the dipstick handle.
• See Capacities and Specifications
(page 292).
If necessary, add fluid in
8 fl oz (250 ml)
increments through the filler tube until the
level is correct.
Type A Type B
If an overfill occurs, excess fluid should be
removed by a qualified technician.
Note:
An overfill condition of transmission
fluid may cause shift and engagement
concerns, and 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.

Ford Motor Company has recommended
maintenance intervals for various parts
and component systems based upon
engineering testing. Ford Motor Company
relies upon this testing to determine the
most appropriate mileage for replacement
of oils and fluids to protect your vehicle at
the lowest overall cost to you and
recommends against maintenance
schedules that deviate from the scheduled
maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or
Ford-authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
This owner's manual and the Ford
Workshop Manual list the recommended
additives and chemicals for your vehicle.
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information. 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, a qualified expert, such
as the factory-trained technicians at your
dealership, should inspect discolored fluids
that also show signs of overheating or
foreign material contamination
immediately.
Make sure to change your vehicle
’s oils and
fluids 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
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
