Also I can't find out how many quarts it takes and whether i should just change the fluid or the fluid and filter. Or if there's a drain plug.

Haha. You said tranny

Change the filter and the fluid… DON't flush it.

Visit a quickie oil change place. Many can suck the old fluid out thru the dip stick tube & then re-fill it.

The 3.8L is a V6 it's not a four cylinder. You probably have the AXOD transmission. Ideally you should be changing the fluid every 30k or so. You should replace the filter and the fluid. Dexron III/Mercon ATF is the recommended type. You'll need between 12 and 14 quarts of transmission fluid for a complete change, but chances are you won't be able to get that much out by just dropping the pan, there's still going to be a few quarts left in the torque converter. So realistically, you'll probably be only to get around 8 or 9 quarts out.
