Interesting Note's Fellow's,as an engine oil & A/T cooler are next on my list.
I too let mine warm to 160/180 before driving hard & normally runs 200 all the time after it warms up (on warm days)
sitting in traffic jams (Atlanta-example) or several hard accelerations & mine's at 220/230
Not sure what temp. will throw it in limp mode? I've heard the A/T will go in Limp if it goes too warm.
Any comment's or suggestion's are welcome.
