Thanks dutch. I read it all, and there are just part numbers everywhere, so I wanted to post up on Lawnsite and be sure before I ordered it.
I'm going to take apart the old trans and maybe rebuild that one. We are still ordering a new one though. I've never rebuilt one, so I'd like to get the new one installed, knowing that it'll work; then sometime during the off-season aka when there is no rush to get it done), take the old one apart and rebuild it.
