Nowadays all fluids compartments on the machine are put through SOS testing (oil analysis). Not sure if there would be enough similarity between automotive transmissions and machinery transmissions to warrant testing, but I could get the lab to run a sample on the fluid that comes out of my transmission (when I flush it) to see what's in there? I've got 115k's on mine.

I worked in the dealership SOS lab many years ago. Can't do much with ATF. They can test for water, but you could see that without a lab. They can test viscosity, but that isn't a critical ATF spec. They could run a mass spectrometry analysis, but that is telling you about the component, not the fluid. It only provides valuable info if you run multiple samples over time and compare the wear rates. Not worth doing with this component, IMO, and definitely not worth doing once.
The most critical things about ATFs are the fluid friction modifiers (additives) for the wet clutch packs which differentiate the various fluid specs. But they can't test for those.
