For anyone doing this at home later: yes, if your pan has a drain plug you can drain through it, but a drain and fill only swaps part of the fluid, because a lot of it stays in the torque converter and the cooler lines. Dropping the pan lets you change the filter too, and doing two drain and fills a few hundred miles apart gets most of the old fluid out. Some converters have a drain plug you can reach through the inspection cover, many don't.

Refill goes in through the dipstick tube, with a long skinny funnel. Use the fluid type printed on your dipstick or in the owner's manual, put in roughly what came out, then check the level with the engine running, the transmission warm, and the selector in Park, and top up a little at a time. Overfilling is as bad as running low, so sneak up on it.
