Hard to say, at this point, whether the fluid supply/return circuits for the converter are plugged with any of the suspicious foreign matter that may have been finer than the screen.

What you find in the governor might provide a clue. If it's not plugged up, all you can do is refill, per the manual and bulletin previously cited (not all 11 at once), and give it a try.

Cross your fingers, but don't hold your breath.

If that doesn't work, then a tear down is in order, but that'll likely cost less than a conversion.

Even if your Ultra manages to come back to life with nothing but clean fluid, you'll wanna drop the pan again, after some miles, to check the screen for further accumulation of foreign matter.
