Trans fluid life is directly related to fluid temps. I would like to hear the driving type at that temp.
Does transmission oil last longer at 160F than at 192?
Amsoil used to have graph that showed tranny fluid life at different temps. I don't know that is that drastic going from 160 to 192 but I think the moral of the story is the hotter the fluid the less longer it lasts.
I think you're right, however, if Ford has designed the transmission to run hotter they may also spec a synthetic transmission fluid to withstand the hotter temperature. I really don't know much about it. The fluid life of the 6r140 is 150,000 miles.
