display, do the following:
1. Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after
several minutes, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK - 3.5L DURATEC/
3.5L ECOBOOST™
6F50/6F55 Transmission (If Equipped) WARNING: The dipstick and
surrounding components are hot. Use
gloves when moving components and
checking the transmission fluid level.
Failure to follow this warning could result
in serious personal injury. Note:
Automatic transmission fluid
expands when warmed. To obtain an
accurate fluid check, drive your vehicle until
you warm it up, approximately
20 mi
(30 km). If you operate your vehicle for an
extended period at high speeds, in city traffic
during hot weather or pulling a trailer, switch
your vehicle off until it reaches normal
operating temperatures to allow the fluid
to cool before checking. Depending on
vehicle use, cooling times could take up to
30 minutes or longer.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, you
should check the fluid level if the
transmission is not working properly. For
example, if the transmission slips or shifts
slowly or if you notice some sign of a fluid
leak.
1. Drive your vehicle
20 mi (30 km) or
until it reaches normal operating
temperature.
2. Park your 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. Put the gearshift lever in park (P) and leave the engine running.
Note: For vehicles with the EcoBoost
engine, move the air filter assembly aside
to access the transmission dipstick.
5. Remove the dipstick and wipe it clean with a dry, lint-free clean rag.
6. Install the dipstick making sure you fully seat it in the filler tube by turning
it to the locked position.

Checking the Fluid Level
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 or engagement
concerns or possible damage.
Correct Fluid Level Check the transmission fluid at the normal
operating temperatures between 180°F
(82°C) and 200°F (93°C) on a level
surface. Drive your vehicle until you warm
it up to the normal operating temperature
after approximately
20 mi (30 km).
Target the transmission fluid level within
the cross-hatch area if at the normal
operating temperature between 180°F
(82°C) and 200°F (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 or engagement concerns or
possible damage. An overheating condition
can cause high fluid levels. If you operate
your vehicle for an extended period at high
speeds, in city traffic during hot weather or
pulling a trailer, you should switch your
vehicle off until your vehicle reaches normal
operating temperatures. Depending on
vehicle use, cooling times could take up to
30 minutes or longer.
