Yes its that simple, you need a 3/8 socket and drain pan. You should replace the crush washer when you do it which runs about $1. I bought fluid from a dealer and it was about $6 a quart. You need 4 for a simple drain and fill but you can do that several times to get a majority of the fluid out. Don't use any other fluid then honda atf-z1, it may cause you problems. If you search the forums there is a nice step by step procedure done.
