Scotty,

 Engines I know something about but transmissions no.

 My 2003 Buick Lasabre has over 100,000 miles with no transmission oil changes.

 Can I suck out one quart of oil through the dip stick tube and then put one quart of clean oil in?

 Would that be to much clean oil at one time?

 As you say, changing oil in a transmission with that many miles chould be disastrous, so what about one quart and no more than one quart.

Thanks

Paul 

PS: Love the videos.

i would not even try that, I'd just leave it alone if it runs fine.
