I also have the Silverleaf dash, and my engine water temperature is controlled very well by the fan, but not so for the transmission. I recently crossed a large mountain in Nevada that has a very long run up as well as down. My guess is more than 10 miles up and then down. Thus the transmission worked hard getting up the mountain and due to the Jake brake it worked hard going down. The transmission temperature peaked at 240 degrees but soon recovered to about 200 on level road. It my understanding that this is OK.
