Item Part Number Description
1 - Correct fluid level at bottom of upper hole and at temperature range 43°C-47°C (109°F-117°F)
2 - Fluid level indicator with crosshatch marks
CAUTION: MERCON®, MERCON® V, MERCON® SP, Motorcraft Premium Automatic Transmission Fluid and Motorcraft Continuously Variable Chain Type Transmission Fluid are not interchangeable transmission fluids. The use of any fluid other than what is recommend will cause transmission damage.
CAUTION: The CVT transmission fluid is a unique fluid and has different expansion characteristics compared to other transmission fluids. Correct CVT transmission fluid level setting must be done with the CVT transmission fluid in the 43°C-47°C (109°F-117°F) temperature range. Setting the CVT transmission fluid level at any other temperature could cause an overfill condition and cause the fluid to leak from the vent and/or cause internal transaxle damage.
NOTE: This procedure is for setting correct CVT transmission fluid level and can also be used to check correct fluid level.
  1. Place the vehicle on a level surface.
  2. Using the special tool, verify that the CVT transmission fluid temperature is in the fluid level setting range of 43°C-47°C (109°F-117°F).
  3. Set the parking brake, place the range selector lever in PARK and run the engine at idle for 5 minutes.
  4. Once the CVT transmission fluid temperature range is in the 43°C-47°C (109°F-117°F) range, place your foot on the brake and move the transmission selector level through all gear positions placing it in PARK.
  5. Remove the fluid level indicator and wipe it with a clean, lint free rag. Place the fluid level indicator back into the fluid level indicator tube.

  7. Remove the fluid level indicator and check for correct fluid level. The fluid level should be at the bottom of the top level indicator hole with the CVT automatic transmission fluid temperature in the 43°C-47°C (109°F-117°F) range.
  8. If CVT transmission fluid needs to be added, add clean CVT transmission fluid in 0.25L (1/2 pint) increments through the fluid fill plug located on the top of the transaxle near the fluid level indicator. Do not overfill the transaxle and make sure the CVT transmission fluid temperature is in the correct range of 43°C-47°C (109°F-117°F), or internal damage to the transaxle will occur.
    • To install, tighten to 35 Nm (26 lb-ft).
    • The wrench light on the dash will illuminate if the CVT transmission fluid level is low during the CVT transmission fluid refill process and the vehicle may experience harsh engagements.
