Trans Opinion - Pic

Hey All, Finally got my donor 904 apart. And it may or may not be good news. The snout of the converter is kinda rough, can feel with finger nail. What could cause that? Also, I found some metal shavings in the pan. What got me scratching my heaad is that some of it was copper in color. What is made of copper in a 904? The trans runs great (no slipping or noises) Shifts real Hard with the Cheetah Turbo Action Reverse Manual Body.....Check the pics, Would you just clean it n just put it back in ???
