These guys don't know what they're talking about.  Here is the proper
procedure:

1.    Place the transaxle range selector lever in PARK and set the parking
brake.

2.    Note: The amount of fluid (fluid level) in the transaxle will affect
the time it takes to drain the transaxle. Make sure to check the fluid
level before proceeding.

    Start engine and check fluid level of the transaxle.

3.    Turn engine off.

4.    Note: If the vehicle is equipped with an air suspension system, the
switch must be placed in the off position before raising the vehicle.

    Raise and suitably support vehicle.

5.    Remove the retainer clip from the lower transaxle fluid cooler tube
and fitting.

6.    Note: On vehicles equipped with 5/16 inch cooler lines, use
Disconnect Tool T82L-9500-AH to disconnect the transaxle cooler tube.
Place the tool on the cooler tube and push the tool into the cooler tube
fitting. This action releases the plastic retaining tabs which holds the
cooler tube in place. Then, pull the cooler tube from the transaxle
cooler tube fitting at the transaxle fluid cooler. On vehicle with 3/8
inch cooler tubes, pinch the plastic retaining tabs of the push connect
fitting and pull the cooler tube to separate it from the cooler tube
fitting.

    Disconnect the lower transaxle cooler tube from the transaxle cooler
tube fitting at the transaxle.

7.    Attach a flexible hose approximately 0.9 meters (3.0 feet) in length
to the end of the transaxle cooler tube and gently fasten the hose with
a hose clamp.

8.    Place the opposite end of the flexible hose into a suitable 14.2
liter (15 quart) container.

9.    Note: When plugging the transaxle cooler tube fitting, make sure the
plug is made of soft material to prevent damage to the internal seal of
the cooler tube fitting.

    Insert a plug into the transaxle cooler tube fitting at the transaxle
to prevent any residual fluid leakage.

10.    Lower vehicle.

11.    Note: When the steady stream of fluid stops flowing the engine
should be turned off to prevent damage to the transaxle. Engine rpm
should not exceed curb idle speed while draining transmission fluid.
Place selector lever in PARK and start engine. Run the engine at idle
while observing the flexible hose attached to the transaxle cooler tube.

    Run the engine at idle speed for approximately 40-60 seconds until the
steady stream of transmission fluid stops flowing. This step will drain
approximately 1.9-2.8 liters (2-3 quarts).

12.    Fill the transaxle with 9.5 liters (10 quarts) of Motorcraft MERCON®
(ATF) Transmission Fluid XT-2-QDX or equivalent meeting MERCON®
specification.

13.    Note: When the steady stream of fluid stops flowing the engine
should be turned off to prevent damage to the transaxle. Engine rpm
should not exceed curb idle speed while draining transmission fluid.
Place the selector lever in PARK and start the engine. Run the engine at
idle while observing the flexible hose attached to the fluid cooler tube.

    Run the engine at idle speed for approximately 2-3 minutes until the
steady stream of transmission fluid stops flowing. This step will drain
approximately 9.5 liters (10 quarts).

14.    Raise and suitably support vehicle.

15.    Remove the plug from the transaxle cooler tube fitting at the transaxle.

16.    Remove the flexible hose from the cooler tube.

17.    Note: Carefully clean the cooler tube before installing it for a
good connection and to prevent fluid leaks.

    Install the cooler tube into the transaxle cooler fitting by pushing
straight into the cooler tube fitting until a click is heard. Then,
gently pull on the cooler tube to make sure the tube is locked in place
in the cooler tube fitting.

18.    Install the retaining clip over the cooler tube and fitting.

19.    Lower vehicle.

20.    Add 1.9 liters (2 quarts) of Motorcraft MERCON® (ATF) Transmission
Fluid XT-2-QDX or equivalent meeting MERCON® specification.

21.    Place the transaxle range selector lever in park, apply the parking
brake and start the engine. Move the transaxle range selector lever
through all ranges allowing the transaxle to engage in each position and
return selector lever to PARK.

22.    Check the transaxle fluid level. The fluid level at normal operating
temperature should read within the crosshatched area of the fluid level
indicator. If the fluid level reads below the crosshatched area of the
fluid level indicator, adjust the fluid level by adding fluid in 0.2
liter (1/2 pint) increments until the correct fluid level is obtained.

23.    Place the air suspension switch to the on position (if equipped).
