Wow. Yeah, that's kinda hard to identify over the internet. Message boards are fun and informational, and I certainly try to help when I can, but not being able to be there in person really does limit my effectiveness.
I'm glad you figured it out, and saved yourself the hassle of pulling the tranny again, although you would have caught on when you started to remove the first bolt.
Good job, and thanks for posting an update!
Take care,
