Removal

CAUTION: MERCON(R)V, MERCON(R)SP, Motorcraft Premium Automatic Transmission Fluid, Motorcraft Continuously Variable Chain Type Transmission Fluid and FNR5 Transmission Fluid are not interchangeable transmission fluids. The use of any transmission fluid other than what is recommended for this transaxle will cause transaxle damage.

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Maintenance/Service and Repair.
2. Remove the front bumper cover.
3. Disconnect the mass air flow (MAF) sensor electrical connector and the wiring harness fastener from the air cleaner assembly.





4. Disconnect the brake booster vacuum hose from the air cleaner outlet pipe.





5. Disconnect the engine breather from the air cleaner assembly.





6. Remove the air cleaner assembly bracket bolt.





7. Loosen the air cleaner outlet pipe clamp at the throttle body and remove the air cleaner and air cleaner outlet pipe assembly.





8. Remove the battery.
9. Remove the battery tray.
1. Disconnect the wiring harness fasteners.
2. Remove the 3 bolts and the battery tray.





10. Disconnect the transmission fluid cooler tube fasteners from the radiator support.





11. Remove the secondary latches from the transmission fluid cooler.





12. Using the special tool, disconnect the transmission fluid cooler tubes from the transmission fluid cooler.





13. Remove the 2 secondary latches from the transmission fluid cooler tubes at the transmission fluid cooler thermal bypass valve.





14. Using the special tool, disconnect the transmission fluid cooler tubes from the transmission fluid cooler thermal bypass valve.





15. NOTE: RH side shown, LH side similar.

Pull up on the tabs on both sides of the radiator support, position the radiator back and remove the transmission fluid cooler tubes from the cooling module.





16. Remove and discard the 2 transmission fluid cooler tube bolts.





17. Inspect the transaxle case to be sure that the transmission fluid cooler tube seals and backing rings were removed with the transmission fluid cooler tubes and are not stuck in the transaxle case. If the transmission fluid cooler tube seals or backing rings are stuck in the transaxle case, remove the seals and backing rings.





18. Loosen the 2 fluid cooler tube fittings and remove the 2 fluid cooler tubes from the transmission fluid cooler thermal bypass valve and the transaxle.





19. Remove the 2 nuts and the transmission fluid cooler thermal bypass valve.





Installation
1. Position the transmission fluid cooler thermal bypass valve in place and install the 2 nuts.
^ Tighten to 9 Nm (80 lb-in).





2. Inspect the transmission fluid cooler tube backing rings and seals for damage and install new backing rings or seals if necessary. Lubricate the transmission fluid cooler tube seals with clean transmission fluid and install the backing rings and seals on the transmission fluid cooler tubes.





3. Position the 2 transmission fluid cooler tubes on the transaxle and tighten the 2 transmission fluid cooler tube fittings.
^ Tighten to 25 Nm (18 lb-ft).





4. Install 2 new transmission fluid cooler tube bolts.
^ Tighten to 9 Nm (80 lb-in).





5. NOTE: RH side shown, LH side similar.

Route the transmission fluid cooler tubes through the cooling module and fasten the upper radiator brackets to the radiator support through the cooling module.





6. Install the transmission fluid cooler tubes in the transmission fluid cooler thermal bypass valve.





7. Install the 2 secondary latches on the transmission fluid cooler tubes at the transmission fluid cooler thermal bypass valve.





8. Connect the transmission fluid cooler tubes to the transmission fluid cooler.





9. Install the secondary latches on the transmission fluid cooler.





10. Connect the transmission fluid cooler tube fasteners to the radiator support.





11. Install the battery tray.
1. Install the 3 bolts.
^ Tighten to 10 Nm (89 lb-in).
2. Connect the wiring harness fasteners to the battery tray.





12. Install the battery.
13. Position the air cleaner assembly in place and install the bolt.
^ Tighten to 11 Nm (8 lb-ft).





14. Tighten the air cleaner outlet pipe clamp at the throttle body.
^ Tighten to 5 Nm (44 lb-in).





15. Connect the engine breather to the air cleaner assembly.





16. Connect the brake booster vacuum hose to the air cleaner assembly.





17. Connect the MAF sensor electrical connector and connect the electrical harness fastener.





18. Install the front bumper cover.
19. Check the transmission fluid level and add transmission fluid as necessary.
