The car has 223k miles on it with a 722.315 transmisson.
I was also able to get all my gears back if I revved the engine high enough, but the transmission only shifts at 3.4 k rpms now, while it was shifting at around 2.0 k rpms before.

Check governor pressure. If regulator pressure is too low, replace centrifugal governor. Ensure control pressure regulating valve."

The above from D911 is the essence of what appears in the MB FSM as probable causes for the symptoms described by AT.
It all points rather strongly to a governor problem.
