Jeff,
There are two ways you can go... unless you're ready to pull the whole tub.
-Pull the engine out
or
-Remove the Tranny and TC
Which direction are you thinking? Both have challenges. Once you decide this, you'll likely have multiple opinions, ideas and helpful hints.
If you can get the pin out of the TC gear shift levers, I think dropping the tranny and TC may be the way to go. If not, pulling the engine may be a better option.
