5. Remove the dipstick, wiping it clean
with a clean, dry, lint free rag.
6. Install the dipstick, fully seating it 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 there is no
indication of fluid on the dipstick and the
ambient temperature is above 50°F
(10°C).
Correct Fluid Level Drive the vehicle
19 mi (30 km) or until it
reaches normal operating temperature.
Check the fluid at the normal operating
temperature of
196°F (91°C) to 215°F
(102°C) on a level surface.
High Fluid Level 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.
An overheating condition 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.
Make sure to use the correct type of fluid.
You can find the type of fluid used on the
transmission dipstick, or in your owner's
manual. See
Capacities and
Specifications (page 219).
If necessary, add fluid in
8 fl oz (250 ml)
increments through the filler tube until the
level is correct.

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

maintenance checks and inspections every
month or at six-month intervals. Check every month
