Hello Everyone!
I grew up as a gearhead, building race engines for my street cars. A close friend of mine has made a very good living as a transmission builder- manual to automatic: Allison, nasty PowerGlides, Muncies and Toploaders. He's built every transmission I've used for the last 36 years (stock Expeditions to 1100 hp BBC powerglides to 500 awhp Subarus).
I mention this because I trust him; he is one of the brightest, most knowledgeable mechanics I've ever known, and I do 99.9% of my own stuff.
I hear a lot on this forum about AT "flushing"- I assume this is the procedure where the fluid change is performed by using pressure through the AT.
On that note, during a 4R75E build he did for me a couple of years ago, he mentioned his AT rebuilds went through the roof when the "flush" machines became the mainstream. His advice was keep doing fluid / filter changes just like we had been doing them for 40 years...
YMMV.

6R80 is just as easy as most autos to service, especially when you add a Performance Automatics or B&M dipstick.
