Saturday I took the wife and kid to the snow. There was a large patch of ice in the road that everyone was getting stuck on. Tires were just spinning and guys were having to have someone stand behind their car or truck and push them. When it was my turn, I also got stuck. The slip light came on and I tried to go easy on the gas, but could not get traction. I put it in 4X4 and crawled through. I was the only one that got through without help. A guy in a 4X2 Tacoma couldn't get through and finally had to back down the hill. I was surprised how helpless I was in 4X2 mode.After all of this, I couldn't get the truck to go back into 4X2 mode. I switched it to 4X2, but the two front wheels on the indicator kept flashing and the truck was still in 4X4. I had to pull of the road and turn the truck off. When I re-started, I was in 4X2. Sorry for the long story, but was that a computer glitch or is that common?
