What a mess... I'd call Chrysler executive customer care. I know the Business center in Texas is a pain to deal with but if you call executive customer care you can get the warranty bit straightened out. If I were you I would check your vin number in a few days if it's not warranty blocked. I would take it to a different dealer and get that fixed, and have the other dealer see the transmission noise. That should be enough for them to warranty the tremec. That transmission has all kinds of issues. Worst case scenario get a lawyer.
