I am getting the P0218 for the second time after some light offroading. It disappears after a couple of days of road usage.
The second time I checked out the trans fluid temp at the end of the trail and it was around 200. However, the P0218 appeared at some point on that trail (I didn't look at the temp while driving). It was a short trip barely 15 minutes and there has been no wheel spinning, low range engaging or anything like that. Just slow driving uphill on a dirt road.
I have the factory trans cooler and the additional fan installed.
Two things bother me now.

- At what temp does P0218 show up? Was the trans oil overheated? Do I have to change it?
- How come the transmission gets so hot with such light usage? Is it a design flaw? How would the truck be capable of doing some more serious offroading without overheating the trans?
