Tom, reread the thread. The OP pulled the cartridge core out of the outer cartridge sleeve, which is still stuck in the body of the valve.
He has reinserted the core, and clipped it in so it won’t run water while he turns the water back on In the house.
The OPs problem is now he needs to remove the outer sleeve.
I don’t have much experience with the new style Moen cartridges, but I once had to run a 1/2-20 tap into the body, and then run the stem of a gear puller into the new thread, and stacking a bunch of hardened washers against the valve body, and pulled it out with the threads.
I figured that the only other option was to replace the whole valve. And since it was in a fiberglass shower, on an exterior wall, replacing the whole valve was a really bad option.
