TRANSMISSION FLUID

Checking 6-speed automatic transmission fluid

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 working properly, (i.e., if the transmission slips or
shifts slowly) or if you notice some sign of fluid leakage.

Transmission fluid should be checked by an authorized dealer. If
required, fluid should be added by an authorized dealer.

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.

TRANSFER CASE FLUID (IF EQUIPPED)

1. Clean the filler plug.

2. Remove the filler plug and
inspect the fluid level.

3. Add only enough fluid through
the filler opening so that the fluid
level is at the bottom of the
opening.

Use only fluid that meets Ford specifications. Refer to the Maintenance
product specifications and capacities
section in this chapter.
