Changed mine last month and the hardest thing was running a tube down to the fill port. I have a rule, make sure you can fill it up before draining any fluid. I bought a funnel with a long plastic tube and tip attached only to discover the tube was too short. I attached the tube to my much longer transmission funnel and was able to drop it down behind the engine right to the fill port without kinking the hose. Remove the bottom drain plug and clean it - it's magnetic so it have some fine metal powder stuck to it. When drained plug it up and have someone up top dump the oil down the funnel. Soon at the oil runs out of the fill port stop and install the plug.
