Mine is in the shop right now for a similar reason. Mine shifted hard into overdrive 6-7 times then started shifting fine again. I dropped the pan and found a few chunks like yours, along with a few pieces that looked like chopped up pencil leads. The tranny shop says it looks like needle bearings. I am getting a rebuild just to be safe. I don't want to risk the tranny grenading on a long trip, if I can help it.
