Transmission service interval

We're trying to put together a list of work that we want done on our annual Nac visit. I've already got airbags on the list, as well as some other, smaller, things. How often should the transmission fluid and filters be changed? Last time was March, 2016, 9200 miles ago.

Synthetic or standard fluid?

Standard now. Should I be switching to synthetic on this old equipment? I've heard both ways.
