I just did this yesterday and was shocked/thrilled about how quick/easy it was. Sure I had to make a trip to the HW store to get some parts for the job but total cost was <$10 and it didn't take much time to find everything.
I swapped in 8 fresh qts of WS and a tube of shudder fix. The old fluid was black (190K miles) and as of the last 2qt flush I did the fluid had returned to a dark red even though 4 qts of the original were still in the system.
Not only was it a quick/clean/easy way to do this without even having to get on the ground my truck was shifting/driving MUCH better right away. Before the ATF swap I'd get the "shudder" after every gear change. Upon the first test drive it only did it around 40mph. The more I drove it the better it got. I only put about 15 miles on the thing before the shudder was completely gone. I can imagine it'll get even better with time.
What a fantastic resource this page and its members are!

When I did this yesterday and was filling the system from a funnel I had hanging above the engine bay I thought the same as you about introducing air but as I poured in the ATF I could see it was forcing the air back up out of the funnel so Im positive it was all purged out.
