Pulled the trans out and tore it down. The fluid was dark and burnt. There was only 13,000 miles on the fluid. The pan had fine metal shavings in it, most of it stuck to the magnets. So far I haven't found anything broken/damaged. The 2-4 band I replaced last January looked like it got hot, but not really worn. The reverse clutches looked similar, blackish but not worn. The rest of the clutch packs looked great. I haven't pulled all the seals out yet to see if any failed. I'm thinking the converter failed and that's where the fine metal came from. There was also a little clutch material sludge in the pan. Time to order parts.
