Fluid - A/T: Service and Repair

TRANSMISSION FLUID DRAIN AND REFILL

Removal

1. WARNING: On vehicles equipped with an auxiliary battery, both the negative and positive battery cables must be disconnected.

WARNING: On vehicles equipped with a 7.3L engine, both the primary and secondary batteries must be disconnected.

Note: All gasoline vehicles will have new adaptive shift strategies. Whenever the vehicles battery has been disconnected for any type of service or repairs 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 operating conditions. There is no time frame set for this process. If a concern is present during down shifts or converter clutch apply, it is not 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 condition is temporary and will eventually return to normal operating condition.
- Disconnect the battery.

2. Raise and support the vehicle.





3. Disconnect the connector.

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

Remove the transmission fluid pan and the 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 bolts and the fluid pan.

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

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





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

6. CAUTION: Be careful not to scratch or damage the aluminum bore. The new seal may leak.





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.





7. On all except vehicles equipped with a 7.3L engine, remove the torque converter drain plug cover.





8. On vehicles equipped with the 7.3L engine, remove the 5 (A) bolts and the (B) flexplate inspection cover.

9. Note: The 7.3L engine-style transmission case is shown, others are similar.





With a drain pan properly positioned, remove and discard the torque converter drain plug. Allow the fluid to drain.
10. Flush the fluid cooler and fluid cooler lines.

Installation

1. Note: The 7.3L engine-style transmission case is shown, others are similar.





After the torque converter has drained, install a new drain plug.





2. On all except vehicles equipped with a 7.3L engine, install the torque converter drain plug cover.





3. On vehicles equipped with the 7.3L engine, install the (A) flexplate inspection cover and the 5 (B) bolts.

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








Select the appropriate (A) 4x2-style or (B) 44-style filter assembly and transmission pan.

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





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

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

Note: 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.





7. Install the (A) pan with gasket. Alternately tighten the (B) bolts.





8. Connect the connector.
9. Remove the supports and lower the vehicle.
10. Connect the battery ground cable.

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

Refill the transmission.
1 Add 6.2 liters (6.5 quarts) of Motorcraft MERCON V (R) Multi-Purpose (ATF) Transmission Fluid XT-5-QM or equivalent meeting MERCON V (R) specification to the transmission through the fluid filler tube.
2 Start the engine. Move the transmission range selector lever through all the gear ranges, checking for engagements.
3 Check and adjust the transmission fluid, in 0.24-liter (0.5-pint) increments, to the proper level (cross-hatched area of the fluid level indicator) at normal operating temperature.
