I got the 30mm nut removed from inside the transmission rear case housing using the 30mm deep well impact socket using the impact power tool. It took 2 seconds. After removing the nut, the output flange came loose and the remaining rod shifter bent inside came out easy.

I then removed all of the 9 bolts from the transmission rear case housing. Drippings of transmission fluid came out. I got the housing loose but not enough to pull it out completely. I tried to pry with a screwdriver, but no luck. Is there some kind of gear pulley type tool to put on the housing in order to remove it? Any ideas, thoughts, comments, feedback, advice is greatly appreciated.
