Special Tool(s)

Transaxle Normal Operating Temperature Fluid Level Check

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: This procedure is only designed to check the transmission fluid level at normal operating temperatures. Do not use this procedure for setting correct fluid level. CVT automatic transmission fluid is a unique fluid and has different expansion characteristics compared to other transmission fluids. Correct fluid level setting must be done in the 43°C-47°C (109°F-117°F) range following the fluid level setting procedure. Failure to follow these instructions will cause damage to the transaxle.

CAUTION: A transaxle that is overfull or under full will cause internal damage and/or cause fluid to leak the vent tube.

NOTE: This procedure is designed for checking the fluid level on a vehicle that has just come in off the road with the transmission fluid in the normal operating range 88°C-92°C (190°F-198°F).

1. With the vehicle in NEUTRAL, position it on a hoist.
2. Place the vehicle on a level surface.
3. Using the special tool, verify that the transmission fluid temperature is in the normal operating of 88°C - 92°C (190°F - 198°F).
4. Once the transmission fluid temperature range is verified, with the engine idling set the park 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.





6. Place the fluid level indicator back into the fluid level indicator tube until it is fully seated, then remove the fluid indicator.
^ Vehicles equipped with a fluid level indicator without crosshatch marks
With the transmission fluid in the normal operating temperature range 88°C - 92°C (190°F - 198°F) the minimum acceptable level would be at the top of the upper fluid level setting hole. The maximum acceptable level would be no more than 12 mm (0.47 inch) up the fluid level indicator from the top of the upper level setting hole.
^ Vehicles equipped with a fluid level indicator with crosshatch marks
With the transmission fluid in the normal operating temperature range 88°C - 92°C (190°F - 198°F) the minimum acceptable level would be at the bottom of the crosshatch mark on the fluid level indicator. The maximum acceptable level would be no higher than the top of the crosshatch (12 mm (0.47 inch) from the top of the upper level setting hole) area.

7. Verify the correct fluid level for normal operating temperature range.
8. If fluid needs to be added, turn off the engine and allow the CVT transmission fluid to cool to the correct level setting range 43°C - 47°C (109°F - 117°F) and follow the transmission fluid level setting procedure for setting correct CVT transmission fluid level.

Transmission Fluid Level Setting





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: CVT automatic transmission fluid is a unique fluid and has different expansion characteristics compared to other transmission fluids. Correct 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 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 fluid level and can also be used to check correct fluid level.

1. With the vehicle in NEUTRAL, position it on a hoist.
2. Place the vehicle on a level surface.
3. Using the special tool, verify that the transmission fluid temperature is in the fluid level setting range 43°C - 47°C (109°F - 117°F).
4. Set the parking brake, place the range selector lever in PARK and run the engine at idle for 5 minutes.
5. Once the 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.





6. 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 fluid needs to be added, add clean CVT automatic transmission fluid in 0.25-Liters (1/2-pint) increments through the fluid fill plug located on the top of the transaxle near the fluid level indicator. Do not over fill the transaxle and make sure the fluid temperature is in the correct range 43°C - 47°C (109°F - 117°F) or internal damage to the transaxle will occur.
^ To install, tighten to 35 Nm (26 ft. lbs.).
^ The wrench light on the dash will illuminate if the fluid level is low during the fluid refill process and the vehicle may experience harsh engagements.
