Hi All,
I have a 2002 Outback H-6 VDC Sedan with 120,000 miles. I have 'changed' the
automatic transmission fluid once by letting the fluid drain out of the
drain plug then refilling until full. I have never done a complete
flush/change-out (torque converter, etc). What are the thoughts about this
method?

Do it again. You're doing just fine.
In my experience, 'flushing' just flushes your wallet of cash. When I was
working for a dealer (used cars) we had two trannies flushed. The first
one waited until we sold it, and then failed about a week later. The
second one had to be flat-bedded about 1 mile from the place that flushed
it.
If the fliud is still, um, at least 'reddish', doesn't have black in it,
and isn't brown, drain and refill again. If it's brown, drain it, fill it,
drive about 3,000 miles and do it again. If it's black, put a Crepe on it,
it's dead... (I had a tranny run 12,000 miles like that..DON'T TOUCH IT!!!).
60,000 miles is about right for a drain and fill. You should be in good
shape.
If you're particularly anal about it, you could disconnect the high
pressure side hose that goes from the tranny to the cooler in the
radiator, with the wheels off the ground start the car, let it warm until
the idle comes down, put it in drive and put the hose in at least a one
gallon container. Five gallons is better. Keep adding tranny fluid to the
inlet as fast as it is running out of the hose. When the stuff running out
of the hose looks new, stop everything, reattach the hose, check the fluid
and add more if necessary. I think you can do this in neutral, too, but we
always did it with the drive wheels off the ground and turning.
