Fluid - A/T: Service and Repair

Removal
All vehicles

1. Note: All gasoline vehicles will have new adaptive shift strategies. 'Whenever the vehicle's battery has been disconnected for any type of service or repair the strategy parameters that are stored in the keep alive memory (KAM) will be lost. The strategy will start to relearn once the battery is reconnected and the vehicle is driven. This is a temporary condition and will return to normal operating condition once the powertrain control module (PCM) relearns all the parameters from the driving conditions. There is no set time frame for this process. If a concern is present during downshifts or converter clutch apply, it is not the fault of the shift strategy and will require diagnosis.

The customer needs to be notified that they may experience slightly different upshifts either soft or firm and that this is a temporary condition and will eventually return to normal operating condition.
Disconnect the battery ground cable.
2. Raise the vehicle on a hoist.

3. Remove the belly pan.
1. Remove the six retaining bolts.
2. Remove the belly pan.
All vehicles





4. If equipped, remove the drain plug to allow the fluid to drain.

5. CAUTION: When replacing the transmission fluid and filter and seal assembly; the torque converter should be drained transmission cooler, cooler lines, and cooler bypass valve must be thoroughly flushed to remove any contamination.

Note: Do not discard the gasket unless damaged. This is a reusable gasket.





Remove the transmission fluid pan and gasket.
1. Loosen, but do not remove the bolts.
2. Remove the front and side bolts.
3. Lower the front of the fluid pan and allow the fluid to drain.
4. Remove the remaining fluid pan bolts and the fluid pan.

6. Note: After removal, discard the filter and seal assembly.





Remove the filter and seal assembly by carefully pulling and rotating the filter as necessary.

7. CAUTION: Be careful not to scratch or damage the aluminum bore. The new seal may leak and damage to the case will result.





If the seal remains in the pump bore, remove it carefully with a small screwdriver so as not to scratch or damage the aluminum bore.





8. Remove the torque converter drain plug cover.





9. Remove the torque converter drain plug.

10. Note:
- If equipped with a radiator in-tank transmission fluid cooler (5.4L) and an Oil-To-Air (OTA) cooler, the in-tank fluid cooler will need to be flushed, and install a new OTA cooler.
- If carrying out the drain and refill procedure for maintenance the installation of a new oil-to-air OTA cooler will not need to be carried out. If carrying out an overhaul the installation of a new Oil-To-Air cooler (OTA) will be required.

Thoroughly flush the cooler lines and the cooler bypass valve.

Installation
All vehicles





1. After the torque converter has drained, install the drain plug.





2. Install the torque, converter drain plug cover.

3. Note: Prior to installation, lightly lubricate the seal with clean MERCON V(R) Multi-Purpose (ATF) Transmission Fluid XT-5-QM or equivalent meeting Ford specification MERCON V(R).





Press a new fluid filter and seal assembly into the pump bore until seated.

4. CAUTION: Mixing (A) 4x2-style and (B) 4x4-style transmission fluid filters and transmission pan assembly components can cause transmission damage.





Install filter assembly and transmission pan.





5. Note:
- Transmission pan gasket is reusable unless damaged.
- Apply a light coat of petroleum jelly to hold the gasket to the fluid pan.
- Position the (A) gasket onto the cleaned fluid pan. Make sure the (B) magnet is positioned over the dimple in the fluid pan.





6. Install the fluid pan.
1. Position the fluid pain.

8. Lower the vehicle.
9. Connect the battery ground cable.

10. CAUTION: Use only Motorcraft MERCON V(R) Multi-Purpose (ATF) Transmission Fluid XT-5-QM or equivalent meeting Ford specification MERCON V(R). The use of any other fluids can result in the transmission failing to operate in a normal manner or failure.

Refill the transmission.
- Add 6.2 liters (6.5 quarts) of MERCON V(R) Multi-Purpose (ATF) Transmission Fluid XT-5-QM or equivalent meeting Ford specification MERCON V(R) transmission fluid to the transmission through the fluid filler tube.
- Start the engine. Move the transmission range selector lever through all the gear ranges.
- Check and adjust the transmission fluid, in 0.24 liter (0.57 pint) increments, to the proper level (cross-hatched area of the fluid level indicator) at normal operating temperature.
