2003 Ford ZX2 AutomaticFACTORY OEM SERVICE PROCEDURE
Main Control Valve Body: Disassembly
NOTE:
Each valve should slide in and out of its bore under its own weight. When a valve will not slide out under its own weight, depending on the valve, push it out with a wire or place the valve body open-side down and lightly tap it with a soft hammer. Never scratch or damage a valve bore. Do not drop the valves or use a valve that has been damaged. Before assembling the valve body, be certain that all valves are clean and lubricated with Motorcraft MERCON® Multi-Purpose Automatic Transmission Fluid XT-2-QDX or equivalent meeting Ford specification MERCON.
NOTE:
Remove the check balls.
