well you could do a 3x drain and fill to make it about 80-90% all new fluid.
another suggestion is to replace the ATF filter
and lastly at least on the 2003 AT there is a train of thought that replacing the 3rd and 4th pressure switches will help a lot and that those switches were the cause for some failures in 7th gen 5AT.
that is all the knowledge I have. I say if you are due for maintenance DO IT! you don't want to end up with me because now I don't have a transmission and if my warranty doesn't cover it I'm screwed lol.
you should also try and use the search button as much as possible there is a lot of good info on here about transmissions already
