i would think the auto's have a pan (manuals don't). you need to drop the pan (bunch or 10mm bolts) change the filter (pop out black thingy). apply new gasket, silicone if you wish, reapply bolts in a crisscross pattern, and the same again to snug them with a tork wrench to spec (i don't know what it would be, call a honda dealership and ask them, they'll tell you), and then fill with fluid (when car is returned to level groud). fluid capacity is in the manual. make sure to check for a while if it is leaking. if so, you messed up putting the gasket on (i've done it a few times
). and always use jack stands, it's time consuming to do this whole change, and jacks can kill ya.
