Secondly, some manufacturers say never to change trans fluid. Those same companies need trannys almost every 100k. So I'm gonna go ahead and worry less about a manufacturer keeping cost of ownership down, and more about my truck lasting. Change the fluid at least every 50k.
I don't disagree totally with you, but a 50k transmission fluid change on the 6R140 is completely unnecessary. That transmission is extremely robust, has a vary large fluid capacity, and has the dual-media filter system which works well. I might think about doing a fluid change at 100k miles.

To each their own. They are good transmissions, but I've replaced enough of them to know that I'll change it more and reduce the risk.
Some do work, but on all the Porsche models I service they go two ways. The customer listens and changes fluids at 50k and the transmission outlasts their ownership. They don't change it, and at 70k I do a $5000 tranny job. More if it's a Cayenne. Sometimes i can replace just the valvebody. It failed due to debris causing damage to valves and solenoids. But that is still $1500. Same with Volvo too. Both of which use ZF. Some of the Mercedes and BMW that use the Aisin trans do a little better, but I replace far more lifetime transmissions than I do with regular intervals. But I see many more interval trannys...

I'd suggest a heated flush for reasons stated above. You change nearly 100% of the transmission fluid that way, and it would be more effective removing contaminants. Draining and filling every 25K isn't a bad idea though.
I wonder why the drain plug isn't at the lowest point of the transmission?

well, since we are conversing about whether we should change tranny fluid at or before 150k AND whether we should flush, filter change etc - let me pose a question....
Why did our tranny pan come with a drain plug if we weren’t allowed to do the partial changes ?

Ford wants to sell you a new 6k transmission at 150k that's why they recommend not changing the fluid until then.
Search this forum and you will find a fleet shop that's rebuilding the 6R140 at 100,000 miles.
