2012 Honda Civic transmission fluid change?

I would like to change transmission fluid in my 2012 Honda Civic.
What is the best way to do it? Do I need to flush it (wash out) or it is OK just to drain old one and put new one. Thanks for advise.

Added (1). Automatic transmission.

Guess what, Hondas have transmission pan drain plugs, because they don't have the UAW making them cut corners on good ideas. The plug is removed using a 3/8" socket drive. Drain it, it should be about 2 quarts, but I always measure what I drain out. Then just refill with Honda type tranny fluid. You can drive it for a few weeks, then do it again. This will get more of the old fluid out. Never pay for a flush. Is it even due for a change?

GO TO HONDA only or read your MANUAL! Honda uses a special type of trans fluid! A genuine HONDA TRANS service is NOT that pricey, and they will give you a WARRANTY and use EXACTLY THE RIGHT FLUID< filters and parts for the JOB! THis is nothing to fool with! Older ones were DRAIN and FILL> Newer ones MAY be more complex! DO NOT TAKE CHANCES! BYE NOW!
