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. MERCON (R) Automatic Transmission Fluid is being replaced by MERCON (R) V as a service fluid, as per TSB 06-14-4.
