Dropped the transmission today, found quite a few issues...

First, all four bell housing bolts were loose, enough so that I didn't even need a wrench to get them out.

Two of the rear driveshaft bolts were starting to come loose.

The rubber in the transfer case mount is hard as a rock, and the stud snapped almost immediately.

The good news is parts did not fall out when I dropped the trans, and there's no obvious damage to the pressure plate or flywheel.

Now I have to just sit and wait until Summit decides to ship the new clutch... I'm probably going to pressure wash the transmission and transfer case, replace the little rectangular side cover gasket that's leaking, and do a bunch of other little things that ultimately won't make the truck more reliable or improve performance, but I'll feel better for having done something.
