Odd . . . my MM has never done that. Does your car have a history of being indecisive? (fuel type, what tires to wear, how to put on its wax today)
Joking aside, you're smart to just do the drain and refill. The fluid for one D+F is 20-30 bucks, and a transmission is $3,000. Risk/reward favors the preventative maintenance heavily. A lot of folks on here like to do the D+F more often than the MM calls out for this reason.
I did the inline filter with a D+F at 136,000. It's technically never called out in the service manual, but again, for $15, I thought it was worth being cautious. A lot of us have used an aftermarket magnefine filter, since it provides better filtration than the OEM one. If you search, you'll find details. That said, with 85k, you can probably wait until your next D+F for this.
