Fluid - A/T: Service and Repair
Transaxle Fluid Drain and Refill1. Place the transaxle range selector lever in the PARK position.
2. Set the parking brake.
3. Start the engine and check the transmission fluid level and condition.
4. Turn the engine off.
5. If equipped, turn the air suspension switch off.
6. Disconnect the battery ground cable.
7. Raise and support the vehicle.
8. Remove the lower retaining clip from the lower transaxle cooler line fitting.
9. Depress the tabs on the plastic insert retainer and remove cooler line from fitting.
10. Attach a flexible hose, approximately 0.9 mm (3.0 ft) in length, to the fluid cooler tube with the other end in a suitable, 15-quart container.
11. CAUTION: When plugging the cooler tube fitting make sure the plug is made of a soft material to prevent damage to the internal seal of the cooler tube fitting. Insert a plug into the cooler tube fitting on the transaxle.
12. Lower the vehicle.
13. CAUTION: When the steady stream of transmission fluid stops flowing, the engine must be turned off to prevent damage to the transaxle. Engine rpm should not exceed curb idle speed while draining the transmission fluid.
Start the engine and run at idle while observing the flexible hose for 40-60 seconds until the steady stream of fluid stops flowing. Turn the engine off. This step will drain approximately 1.9-2.8 liters (2-3 quarts) of transmission fluid.
14. Fill the transaxle with Motorcraft MERCON V Automatic Transmission Fluid X-T5-QM or equivalent meeting Ford specification MERCON V(R).
15. CAUTION: When the steady stream of transmission fluid stops flowing, the engine must be turned off to prevent damage to the transaxle. Engine rpm should not exceed curb idle speed while draining the transmission fluid.
Start the engine and run at idle while observing the flexible hose for 2-3 minutes until the steady stream of fluid stops flowing. Turn the engine off. This step will drain approximately 9.5 liters (10 quarts).
16. Raise and support the vehicle.
17. Remove the plug from the cooler tube fitting.
18. Remove the flex hose from the cooler tube.
19. Note: Clean the cooler tube fitting before installing it to verify a good connection and to prevent any leaks.
Install the lower cooler tube.
20. Install the lower retaining clip
21. Lower the vehicle.
22. Fill the transaxle with Motorcraft MERCON V(R) Automatic Transmission Fluid X-T5-QM or equivalent meeting Ford specification MERCON V(R).
23. Move the transaxle range selector lever through all the ranges allowing the transaxle to engage in each position.
24. Check the transaxle at normal operating temperature. Fluid should be within the crosshatched area of the fluid level indicator. If the fluid is not within the crosshatched area add fluid in 0.2365 liter (1/2 pint) increments until the correct level is achieved.
25. If equipped, turn the air suspension on.
26. Note: When the battery is disconnected and reconnected, some abnormal driving symptoms may occur until the vehicle relearns its adaptive strategy.
Connect the battery ground cable.
