Creat a safe working environment for automatic transmission fluid and filter replacement by suspending your vehicle and placing a drain pan beneath its Oil Pan. The range selector cable bracket can stay in place with the bolts removed so the transmission Oil Pan Drain Plug can be removed to expose the pan while it descends. Complete the Oil Pan bolt removal at the front sections and sides while turning the rear bolts four times before tapping the pan gently with a rubber mallet to release fluid. Drain the Oil Pan then you should remove the remaining pan bolts followed by the removal of both the Oil Pan and gasket. Use a safe grip to spin the filter and afterward remove the stuck filter seal using pliers. Please check the fluid color and filter contents for clutch material as well as bronze slivers and steel particles before discarding the seal. You must clean the surfaces of the transmission case and Oil Pan gasket with solvent while removing all traces of old gasket material. Apply automatic transmission fluid to coat the installation end of the new filter seal before threading it inside the transmission case using the proper socket to finalize installation. Proceed by installing the new filter and then placing the Oil Pan along with its new gasket. Alternating and evenly distribute torque when tightening the Oil Pan to transmission case bolts to 11 nm (97 inch lbs.).
