Metal in the pan, shifts good, fluid great any guesses before I pull it down?

Normal wear materials don't look like that, and there are no other parts in that transmission that are expendable. Since so much of it appears to be aluminum, and so few parts in there are made of aluminum, it could be very serious; cuz that is just NOT supposed to happen.
About the only choices are; thrust washers, the governor support, the servos, and sometimes, the planetaries. And of those, the only ones that also have bronze/brass in them are the planetaries, and the thrust washers.
'Course, all those materials are also found inside the convertor............
