At 180k, I'd be leery of changing the filter. Usually best to leave it at that kind of mileage if it has never been changed.
That said, you can change the fluid if you like - but only do a little bit at a time. Drain out a small amount, then fill the trans up with fresh fluid, drive it around for a few days, repeat a good few times until the fluid you're draining is all new.
Auto transmissions can get real pissy at higher mileages if it's run the same fluid/filter the whole time. Changing fluid can actually create issues, unless done very, very gradually.
My Cavalier had 256k miles (before I wrecked it), and I had no interest in changing the brown trans fluid, since I knew that car's attitude towards me helping it.
