Is anyone else having issues overheating in 4WD? We started going off roading (narrow dirt road, a few small creeks to cross, no big rocks) yesterday and after a few miles in 4WD I started getting messages that the transmission was overheating and I needed to step on the brakes or drive over 5mph. Neither helped, nor did letting the jeep sit for awhile. You can also hear the engine getting really loud trying to cool itself unsuccessfully. I had to drive a few minutes at a time until I could get back to 2WD which drove fine. Not cool!
