Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes. Your transmission doesnot consume fluid. However, the fluid levelshould be checked if the transmission is notproperly working. For example, if thetransmission slips or shifts slowly or if younotice some sign of fluid leakage. SeeScheduled Maintenance (page 504).
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.
6F55 Transmission (If Equipped)
WARNING: The dipstick andsurrounding components are hot. Use gloveswhen moving components and checking thetransmission fluid level. Failure to follow thiswarning could result in serious personalinjury.
Note:Automatic transmission fluid expandswhen warmed. To obtain an accurate fluidcheck, drive the vehicle until it is warmed up(approximately 20 mph (30 km/h). If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be switched off until normal operatingtemperatures are reached to allow the fluidto cool before checking. Depending onvehicle use, cooling times could take up to30 minutes or longer.

Checking the fluid level
Low fluid level
If the fluid level is below the MIN range ofthe dipstick, add fluid to reach the hash marklevel.
Note:If the fluid level is below the MIN level,do not drive the vehicle. An underfillcondition may cause shift or engagementconcerns or possible damage.
Correct fluid level
The transmission fluid should be checked atnormal operating temperature 180°F-200°F(82°C-93°C) on a level surface. The normaloperating temperature can be reached afterapproximately 20 mph (30 km/h) of driving.
The transmission fluid level should betargeted within the cross-hatch area if atnormal operating temperature 180°F-200°F(82°C-93°C).

High fluid level
If the fluid level is above the MAX range ofthe dipstick, remove fluid to reach thehashmark level.
Note:Fluid level above the MAX level maycause shift or engagement concerns orpossible damage. High fluid levels can becaused by an overheating condition. If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be switched off until normal operatingtemperatures are reached. Depending onvehicle use, cooling times could take up to30 minutes or longer.
Adjusting Automatic Transmission FluidLevels
Before adding any fluid, make sure thecorrect type is used. The type of fluid usedis normally indicated on the dipstick and alsoin the Technical Specifications section in thischapter.
Note:An overfill condition of transmissionfluid may cause shift or engagementconcerns or possible damage.
Do not use supplemental transmission fluidadditives, treatments or cleaning agents. Theuse of these materials may affecttransmission operation and result in damageto internal transmission components.Reinstall the air filter assembly. After the fluidlevel has been checked and adjusted asnecessary, do the following:
1. Shut the engine off.
