I like to see trans temperature reach 220 occasionally. Water condenses in the trans oil and needs to be boiled out occasionally.
I like your theory, but in 30+ years of driving and exclusively wrenching on all my own stuff and some for others, I have never come across that issue in any vehicle new or old save for maybe one that was severely neglected.
And if it was even remotely an issue, I don’t believe most auto trans mfgs would design them where they ideally Never reach anywhere near that high of oil temperature.
You are way behind the times. Fords new transmissions have used increased temperatures to make them more fuel efficient. Normal operating Temps are 200 to 259. See:
