I have a 1999 Dodge Ram 1500 5.9L V8 with an automatic transmission and with 130k miles on it. The weather here has been below freezing all week, but it was around 10 degrees when I drove the truck in 4High about 3 miles. I hit some ice and the truck slid backwards down a hill. When I went to shift the truck into reverse, and then into drive, to get myself out of the situation, the truck wouldn't shift. The gear shifter would move freely through its entire range, but the truck itself would not change. Also, the red indicator strip on the dashboard which tells you which gear you are in was sticky and wasn't following the path of the gear shifter. I was able to wiggle the shifter enough to get it into reverse, but then on the way home we pretty much coasted downhill in neutral. I was unable to put the car in park and had to leave it with the key in it, turned off but still in gear. No matter what I did the transmission wouldn't shift out of neutral. When I went to put it in park it made a horrible grinding noise that continued until I put the truck back in neutral. I haven't had this truck long, but have noticed it will occasionally be hard to switch into and out of 4WD and sometimes it will be hard to put it into the correct gear. I know gear isn't the right word when talking about Drive, Reverse, Park, but that's what I mean. It was above freezing and sunny today so I went and started the truck and was able to put it into park and take the key out, but I didn't dare drive it for fear of getting stuck down the road. I thought maybe the linkage got frozen, but the extent of my knowledge comes from Click and Clack. Any help would be SUPER SUPER appreciated, since I'm pretty clueless. THANK YOU!
