Yes I do. I formulate ATF's, MTF's, engine oils, gear lubes, and specialty lubricants so I know every component involved in ATF chemistry.

You are right that fluid is low cost compared to a transmission. But your recommendations will result in spending more money on fluid, and the transmission's life will not be prolonged if you took the fluid out to 50,000 miles on most vehicles.
Spending more money, yes, but your last sentence is disputed.
100,000 mile FF is pure marketing hype and is a wet dream and only valid if you drive 5000 miles a years at less than 55 mph.
The whole 100,000 mile FF is an attempt to convince the owner or prospective owner that he can avoid some lifetime maintenance costs but doesn't tell him of increased wear and potential failure.

I drained the Dex 6 out of my Silverado at 50,000 miles (with half of those miles towing a 5,500 pound trailer) and visually it STILL looked good.
Visual observation tells you anything about wear, only if it MIGHT be oxidized.
So it says "Iowegian" is your name. Do you live in Iowa? If so, I'd like to know who in Iowa is formulating anything beyond corn syrup...
