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 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.
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.
