Lubricants and fluids used on your vehicle are hazardous waste and must be disposed of properly; when disposal is required, place the waste into a sealable container and deliver it to a service station, auto parts store, or other facility that accepts hazardous waste for recycling. At specified time intervals, the transmission fluid should be drained and replaced, and this procedure should only be performed after the engine has cooled down completely. Before beginning work, purchase the specified transmission fluid and a new filter, and gather necessary tools including jackstands to support the vehicle, a drain pan capable of holding at least eight pints, newspapers, and clean rags. Raise the vehicle and support it securely on jackstands, then place a drain pan underneath and remove the front and side pan mounting bolts, loosening the rear pan bolts approximately four turns. Carefully pry the transmission pan loose with a screwdriver to allow the fluid to drain, then remove the remaining bolts, pan, and gasket, cleaning 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, ensuring any magnet inside the oil pan is cleaned and replaced in the same location. Remove the filter and O-ring from the mount inside the transmission, install a new filter and O-ring, and ensure the gasket surface on the transmission pan is clean before installing a new gasket. Position the pan against the transmission and tighten each bolt a little at a time until reaching the final torque. Lower the vehicle and add the specified amount of automatic transmission fluid through the filler tube, then, with the transmission in Park and the parking brake set, run the engine at a fast idle without racing it. Move the gear selector through each range and back to Park, checking the fluid level, and inspect under the vehicle for leaks during the first few trips.
