Rode up a steep rocky hill today with Commander. 1/3 of the way up, I started getting a loss of power almost like faulty spark plugs. I was in 4wd and high gear. The unit slowed to the point that I almost rolled over backwards as I needed more upward thrust on the hill. I was finally able to stop on a semi flat spot but the engine did not have enough power to climb the 45 degree hill. My dealer said I probably burned the clutch belt because I went up the hill in high gear instead of Low gear. Any ideas? Low gear would not have produced enough speed to get over the hill. This is a hill that I climb with my Honda Rubicon. I saw several ATV's come up after I wenched myself to the top so it was not that bad of a hill. I am afraid to trust the Commander on another hill climb if it is not designed to climb like an ATV. My dealer wants to sell me a heavy duty clutch upgrade to correct a problem that should have been a warranty issue. Any advice appreciated.
