727 TC Installed - Probably Wrong...

So, I installed the engine and transmission together into the car about a month ago. I did not try to turn the engine over after connecting the transmission and engine until last night.

Couldn't get it to budge.

After some research seems like the TC may have been installed incorrectly (by me... whoops) and probably broke the pump gear.

My questions at this point:

-Anything else to check?
-How can I disconnect the TC if I cannot spin it to reach all 4 bolts?
-Do you think I can drop and tilt the transmission enough to just pull it backwards off the TC?

Anyway, thanks in advance for the help. FABO is the best.
