Well, I don't know the exact details or what's covered the post you found. But when I had mine changed I did it with a family friend whose a mechanic. He put a wood block on top of the floor jack disc and then positioned it on the block in front of the oil pan and lifted till clear. The thing to know though is that your transmission will probably need some small adjustments afterward, nothing major just some tuning. All in all it's a pretty quick fix.
