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.
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 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, 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 in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lintfree rag. If
necessary, refer to Under hood overview in 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. See Moving 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.
