2020 LINCOLN MKZ transmission

You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to pull off the road. You can
continue to drive your vehicle.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.
If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P). 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
6F35 Transmission
(If Equipped)
Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.
The automatic transmission does not have
a transmission fluid dipstick. Refer to your scheduled maintenance
information for 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
properly working. For example, if the
transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
See
Scheduled Maintenance (page 475).
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.

Note:
Automatic transmission fluid expands
when warmed. To obtain an accurate fluid
check, drive the vehicle approximately 20 mi
(30 km) until it is warmed up. 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 switched 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 your scheduled maintenance
information for 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. For example, if the

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 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 mi (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 or engagement concerns 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 switched off until normal operating
temperatures are reached. Depending on
vehicle use, cooling times could take up to
