2004 5.4 transmission leak

[46L281GT]

My 2004 has developed a transmission leak i believe around the pan. If I leave it sitting overnight I'll get a stop in my driveway about the size of piece of printer paper. It is slightly low (maybe 1/4 of a quart)

So I'm going to drop the pan and refill it. Should I replace the filter while i have it out or leave it alone. I've heard mixed opinions on this. It has 135k miles currently. Thanks!

Replace the filter while you're at it. Wont affect anything.

Thanks! I'll take a picture of the leak and make sure it is leaking in the spot that I think it is.
