Transmission Fluid Drain and Refill

Specifications:

CAUTION: MERCON (R), MERCON (R) V MERCON (R) 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 recommended for this transmission will cause transmission damage.

Draining
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the transmission fluid drain plug and allow the fluid to drain.

Refill
3. Install the transmission fluid drain plug.
^ Tighten to 47 Nm (35 ft. lbs.).

4. Remove the transmission fluid fill plug.

5. Fill the transaxle with approximately 4.7L (5 quarts) of clean automatic transmission fluid.
6. Install the fluid fill plug.
^ Tighten to 39 Nm (29 ft. lbs.).

7. With the transaxle in (P) PARK, the vehicle should be on a level surface, the engine at idle (680 - 780 rpm), foot pressed on the brake, move the selector lever through each gear and allow engagement of each gear. Place the selector lever back in the PARK position.
8. Wipe the fluid level indicator cap and remove the fluid level indicator.
9. Wipe the fluid level indicator with a clean cloth.

10. NOTE: In order to get an accurate fluid level reading, the vehicle should be on a level surface, the engine at idle (680 - 780 rpm) for 5 minutes and the fluid temperature should be at least 70 degrees C - 80 degrees C (158 degrees F - 176 degrees F) using the scan tool.

If fluid needs to be added, add 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 fluid. Install the fluid level indicator back in the fluid filler tube until it is fully seated, then remove the indicator. The fluid level should be at the upper-most mark on the fluid level indicator. Only fill to the upper-most mark on the fluid indicator. Do not overfill. Damage to the transaxle will occur.
