Picked up the transmission recently as well, TH400.
The bell-housing took forever to get, it was on back order for months, they had some tooling issues.
Here is the pressure relieve valve for the transmission lines running to the front cooler. Just another safety precaution, I try my best to learn from other's breaking points and attempting to incorporate their solutions when I can. Highly recommended by HPP. Another one of those items that I trust my tuner's advice. Very pleased with how much help HPP gives me.
Picked up the shifter as well:
