They say the Dexron VI is backwards compatible for GM Transmissions. What do y'all say?>

No. Too thin and doesn't live up to the better heat blah blah blah ... Wiped enough of it off the rear tailgate after transmissions in other things smoked off.
Whoa there hoss. Why are you flushing?
when a transmission dies and you rebuild/ replace it- flush lines and cooler.
Only time to flush a transmission is you know you are replacing it but HOPE to squeeze another 5,000 miles from it- maybe.
otherwise you don’t flush.
Huh? I’ve twice flushed the trans on my wife’s 4Runner. I pull the return line from the cooler to the trans and place in a bucket. Start vehicle, dump 2 quarts, shut off, add 2 quarts, repeat until fluid is clear. Simple pan drain and filter change gets about 3 to 4 quarts, leaving another 9 quarts of dirty used fluid in the trans.
@Big T I like your idea on that type of flush. It gets all the old fluid out that has degraded over time with fresh fluid in
I would like to hear what others think that know tranny’s. I may do this myself if it’s a good route
My 96 was still going at 306 k. These are stout tranny's
