FORD 2013 F-150 v.3 - Manual (Page 333)

AUTOMATIC TRANSMISSION FLUID CHECK
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 working properly, (i.e., if the transmission slips
or shifts slowly) or if you notice some sign of fluid leakage.
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 CHECK (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 Capacities
and Specifications section.
