Yes just change all the fluid and filter. Do not do a flush with that many miles, just change. From what my dad (ford tech) has been saying about when I do mine soon, there is a plug in the tranny housing under the torque converter that you can take out, then take a plug out of the converter. Doing that and dropping the pan should get almost all the fluid and only leave like a quart let in some places. Just dropping the pan you'd be lucky to get half the old fluid out. Should be changed more often than that too, mine should be at 40k this summer when i do it and i just changed my diffs and transfer case here at 35k.
Maintenance is cheaper than fixing!
