I have an 08 teryx and it has given me only a few very minor issues until today. I was ridding along a very wet and muddy trail. Getting up some of the hills took some work, but nothing i haven't done many times before. While going up a moderatly sloped hill all I all of a sudden heard a bang/crack noise and the machine stopped moving forward. The engine was still running as it normally does, but I am now unable to put the machine into any gear, it's a sitting duck. I had to get towed back to the truck. Any idea what I might be dealing with?
