TRANSMISSION FLUID CHECK
6F50/6F55 Transmission
WARNING:The dipstick cap and surrounding components may
be hot; gloves are recommended.
WARNING:Use gloves when moving the air filter assembly;
components will be hot.
Note:
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up (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 until normal operating temperatures are
reached to allow the fluid to cool before checking. Depending on vehicle
use, cooling times could take up to 30 minutes or longer.
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.
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 a minimum of 10 seconds for each gear to engage.
4. Latch the gearshift lever inP(Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lintfree rag. If
necessary, refer toUnder hood overviewin this chapter for the location
of the dipstick. (For vehicles with the EcoBoost engine, move the air
filter assembly aside to access the transmission dipstick. SeeMoving the
Air Filter Assembly (EcoBoost engine)for more information.
6. Install the dipstick making sure it is fully seated in the filler tube by
turning it to the locked position.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated areas for normal operating temperature.

7. Without disconnecting the sensor (4), pull the air filter assembly up to
disconnect the air filter assembly from the seated grommets located
underneath the air filter assembly.
8. Rotate the air filter assembly
90 degrees counterclockwise and
reinstall into the rubber hose.
9. Tighten the clamp (1).
10. The transmission fluid level indicator can now be accessed.
Low fluid level
If the fluid level is below the MIN
range of the dipstick, add fluid to
reach the hash mark level.Note:If
the fluid level is below the MIN level,
do not drive the vehicle. An underfill condition may cause shift and/or
engagement concerns and/or possible damage.
Correct fluid level
The transmission fluid should be checked at normal operating
temperature 180°F-200°F (82°C-93°C) on a level surface. The normal
operating temperature can be reached after approximately 20 miles
(30 km) of driving.
The transmission fluid level should be
targeted within the cross-hatch area
if at normal operating temperature
180°F-200°F (82°C-93°C).

High fluid level
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.Note:
Fluid level above the MAX level may
cause shift and/or engagement concerns and/or possible damage.
High fluid levels can be caused by an overheating condition. 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 until normal operating temperatures are reached. Depending
on vehicle use, cooling times could take up to 30 minutes or longer.
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 theTechnical
specificationssection in this chapter.
Note: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.
Note: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:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees clockwise without
disconnecting the sensor.
