WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

With the vehicle in NEUTRAL, position on a hoist. For additional information, refer to JACKING & LIFTING .
Disconnect the in-tank fluid cooler return tube (top fitting) from the transmission.
Connect one end of a 9.25 mm (0.3750 in) inner diameter x 1,500 mm (60 in) long hose to the in-tank fluid cooler return tube and insert the other end into the fluid fill hole in the transmission case.
Start the engine and run it at idle with the transmission in NEUTRAL.

CAUTION: The fluid flow must be steady (without air bubbles) to make sure of an accurate reading.

Remove the end of the hose from the fluid fill hole in the transmission case and place it into a measuring container for 15 seconds. After 15 seconds, insert the end of the hose back into the fluid fill hole in the transmission case.
Turn the engine off.
Measure the amount of fluid in the container. If the amount of fluid measured is approximately 600 ml (20.4 oz), the transmission fluid cooling system is functioning correctly. Reinstall all of the components. If the amount of fluid measured is not as specified, proceed as follows:
