Transfer Case problems of the 2011 Dodge Ram 1500

While driving at 45mph, the truck suddnely and violently downshifted and skidded to a nearly immediate stop with no need to depress the brakes. Luckily there were no vehicles behind me as it surely would have resulted in an accident. Immediatley, a strong foul smell and smoke was noticed coming from under the hood. After putting the car in park and lifting the hood, the smoke dissipated immediately, but I found later that putting the truck into reverse or drive had absolutely no affect. Even placing the truck into neutral would not allow the truck to roll. The truck required a flatbed tow to the dealership as the rear wheels would not easilly roll forward, and would not roll in reverse. The tow driver needed to place the rear wheels on skids and slide the truck off the flatbed. The dealership found they needed to forcibly manipulate the transfer case to get the truck into neutral as it was seized. They have found that the c2 and underdrive clutches are both completely destroyed, and there are significant amounts of metal shavings in the transmission oil and pan. They said they have never seen such a completely destroyed clutch on any low milage vehicle. The transmission system was sealed, and pressure tested as expected. They are currently investigating for root cause and to bound the extent of the damage. The truck is supposed to have safety features of both a "limp mode" for the transmission, as well as a further safety feature to go into neutral in such catastrophic failure, both safety mechanisms failed in addition to the transmission. Multiple transmission systems failing in such a way, and yet it is likely (already positioning without root cause) that Chrysler will want to rebuild the transmission rather than replace it as they should. I'm not confident that this transmission can be repaired such that it will not fail again in short order. Dangerous.
