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 and also in the
Maintenance product specifications and capacitiessection in 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.
For vehicles equipped with the EcoBoost engine, reinstall the air
filter assembly.
After the fluid level has been checked and adjusted as necessary, do the
following:
A. Shut the engine off.
B. Loosen the clamp holding the air filter assembly to the rubber hose.
C. Rotate the air filter assembly 90 degrees clockwise without
disconnecting the sensor.
D. Seat the air filter assembly back into the grommets by pushing down
on the air filter assembly.
E. Tighten the clamp.
F. Install and tighten two bolts that attach air filter assembly to the front
of the vehicle.
G. Install the bolt cover (if equipped).
H. Reinstall the harness retaining clip into the front of the air filter
assembly.
