Well since you only wanted Matt to answer, I won't...
60K drain and fill is normal per the FSM, although if you do towing and severe duty stuff (note: driving in traffic every day is not "severe duty" as far as this
particular application is concerned) the manual mentions every 30K
inspection.
A shop with a transmission fluid exchange machine would get almost everything out, if you feel like paying the extra money to go that route. That would be beneficial but is not necessary for most.
