Check Transmission Fluid Level

WARNING: This page is about a different car, the 2009 Mercury Milan and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The vehicle should not be driven if the transmission fluid level is below the bottom line on the transmission fluid level indicator and the ambient temperature is above 10°C (50°F) or damage may occur.
NOTE: Transmission fluid expands when warmed. To obtain an accurate transmission fluid level check, drive the vehicle until normal operating temperature is reached, approximately 32 km (20 mi).
NOTE: If the vehicle has been operated for an extended period at high speeds, in city traffic during hot weather or while pulling a trailer, the vehicle should be turned OFF for approximately 30 minutes to allow the transmission fluid to cool before checking.
NOTE: Incorrect transmission fluid level may affect the transaxle operation and could result in transaxle damage.

Under normal conditions, there is no requirement to check the transmission fluid level. However, if the transaxle is not functioning correctly (the transaxle may slip, shift slowly or there may be some sign of fluid leakage), the transmission fluid level should be checked.

  1. Drive the vehicle 32 km (20 mi) or until the vehicle reaches normal operating temperature.
  2. Park the vehicle on a level surface and engage the parking brake.
  3. With one foot on the brake, start the engine and move the selector lever through all the gear ranges. Allow sufficient time for each gear to engage.
  4. Place the selector lever in PARK and leave the engine running.
  5. Remove the transmission fluid level indicator and wipe it clean with a lint free cloth.
  6. Install the transmission fluid level indicator, making sure that it is fully seated in the filler tube.
  7. Remove the transmission fluid level indicator. The transmission fluid should be within the designated areas.
