These were the average temps.
These were the minimum temps
I like that the temps stay within a ~20°F range once it is up to temp regardless of speed, load or ambient temp. I have a 160F thermal bypass which could lead to problems but it has been rock solid thus far. Running at 156F it seems that in some cruising conditions the 4L85E does not even need external cooling other than what it recieves from airflow over the pan and unit. I see guys installing the Trucool 40K on these without a bypass and know that their trans is overcooling in cool weather.
