How to drain and replace transmission fluid and Filter on Mercury Grand Marquis?

At the specified intervals, the transmission fluid should be drained and replaced. Since the fluid will remain hot long after driving, perform this procedure only after the engine has cooled down completely. Before beginning work, purchase the transmission fluid specified in Recommended lubricants and fluids, a new filter, and gaskets. Never reuse the old filter or gasket! Other tools necessary for this job include jackstands to support the vehicle in a raised position, a drain pan capable of holding at least eight quarts, newspapers, and clean rags. Raise the vehicle and support it securely on jackstands. With the drain pan in place, remove the front and side transmission pan mounting bolts. Loosen the rear pan bolts approximately four turns. Carefully pry the transmission pan loose with a screwdriver, allowing the fluid to drain. Don't damage the pan or transmission gasket surfaces, or leaks could develop. Remove the remaining bolts, pan, and gasket. Carefully clean the gasket surface of the transmission to remove all traces of the old gasket and sealant. Drain the fluid from the transmission pan, clean it with solvent, and dry it with compressed air. Remove the filter from the mount inside the transmission. Install a new seal, gasket, and filter. Tighten the mounting bolts securely. Make sure the gasket surface on the transmission pan is clean, then install a new gasket. Put the pan in place against the transmission and install the bolts. Working around the pan, tighten each bolt a little at a time until the final torque figure is reached. Don't overtighten the bolts! Lower the vehicle and add about four or five pints of automatic transmission fluid through the filler tube. With the transmission in Park and the parking brake set, run the engine at a fast idle, but don't race it. Move the gear selector through each range and back to Park. Check the fluid level. Add fluid if needed to reach the correct level. Check under the vehicle for leaks during the first few trips.
