Most 8HPs are happy around 215F. I don't have a 70 yet, but thats where the 8HP45 sits at during normal driving. It MUST get above 212 to boil off any condensation, so that seems about right.

The Mopar guys are saying their 8HP70 Rams run at around 190 during normal driving and 200 when towing. That seems a bit low to me.
