I got a '19 3500 wit the aisin. ive noticed that in heavy traffic the trans and engine temps rise. Engine is 192-200 and trans is 165-175. If i turn the AC on within 1-2 min the engine will be at 186-188 and the trans 158-162. I can almost duplicate these conditions and i cant explain why the AC being turned would have this effect. Any one else experience this?
