If it only took 8 quarts with a pan drop, you must have been low on fluid or had it at a big time angle. Mine takes 12 quarts when I change the internal filter and drop the pan, and every other Super Duty I've seen takes about the same.
If you change the fluid at the recommended intervals, you're fine not flushing the converter. The fluid is actually very clean if you change it and the external filter every 30k, hence the reason for that interval. It would cost a fortune to flush all the old fluid out with that frickin $5 a quart mercon SP.
