No one claimed that excessive heat "is the same temperature as it was 70 years ago." Please try to pay attention to context and what the actual text states.
It still stands however that anyone who is ignorant enough to pull a trailer "all day long" at 250 degree (lol) transmission temps is asking for exactly what they will get.
Of course, a competent tow vehicle wouldn't run at such temps...but that's for another discussion.
