For information on Ford Color Coded Illustrations refer to OEM COLOR CODING INFORMATION

Inspection 

NOTE: The vehicle should not be driven if the transmission fluid level is low. Internal failure could result.
NOTE: If the vehicle has been operated for an extended period at high highway speeds, in city traffic, during hot weather or while pulling a trailer, the transmission fluid must cool down to obtain an accurate reading.
NOTE: If a new transmission fluid cooler or new fluid cooler tubes have been installed, drive the vehicle to warm the transmission fluid to 96 deg.C-101 deg.C (206 deg.F-215 deg.F) in order to purge the air from the transmission fluid cooling system.
  1. Connect the diagnostic scan tool and position the vehicle on a hoist. Refer to: Jacking and Lifting .
  2. If equipped, release the retainers and remove the splash shield.

    Fluid Level Indicators with Letters 

  6. NOTE: The transmission fluid level indicator uses A and B to indicate the fluid level. The different areas are for different vehicle models. The correct transmission fluid level is within the B area on the transmission fluid level indicator.
    NOTE: Do not overfill the transmission.

    Using the scan tool verify the transmission fluid temperature is between 96 deg.C - 101 deg.C (206 deg.F - 215 deg.F). The transmission fluid level must be within the B area on the transmission fluid level indicator.

    Fluid Level Indicators with Numbers 

  7. NOTE: The transmission fluid level indicator uses 1 through 6 to indicate the fluid level. The different numbers are for different vehicle models. Use the area between 5 and 6 when checking the transmission fluid level. The correct transmission fluid level is between 5 and 6 on the transmission fluid level indicator.
    NOTE: Do not overfill the transmission.

    Using the scan tool verify the transmission fluid temperature is between 96 deg.C - 101 deg.C (206 deg.F - 215 deg.F). The transmission fluid level must be between 5 and 6 on the transmission fluid level indicator.
