The stuff that looks like aluminum paint is normal wear material, but you had more than I would like to see.

Metal shavings are always bad news, at least that means the friction materials is all gone and you are running metal to metal on the clutches. Total failure isn't far away.

Brass shavings mean the pump is gone, bits of other stuff usually means bearings.

Please check your flex disk before driving again, it may be coming apart.

However, if the tranny is making groaning or screeching noises at any time, it's rebuild time.
