hey guys i have an 02 duramax with a ppe hot 2 and was wondering what normal operating temps for the 5 spd were. i live in nebraska and in the summer it gets up to 95 100 degrees out and in town i usually run around 190-210 with no load and was wondering if thats a little on the hot side? and if so whats the best auxillary cooler to run or do i just need to back flush my oil cooler. whats the best plan of attack?

 

I Drive long trips for work in my Dmax and my trans temp sits between 180 to 200degrees when the outside temp is 80-90degrees so i would say that it dosnt seem too far off. never hurts to get a trans service though
