904 just gave up

how do I check to see if that's what I did.
Good old slant 6 great engine.
you know that happened so long ago, I don't remember if I towed it home or if I limped it home. I do know that it was leaking fluid out of the front seal area of trans. Local TF guru, said it was fairly common occurrence for the converter neck to crack on 904's. When I pulled it, damned if he wasn't dead on right. I don't know if or when Ma Mopar redesigned that converter neck flaw.
