I just had my clutch modified by an outfit, who at this point will remain nameless. They claimed that their work would give me an underdrive and an overdrive, like having two extra gears. Every thing seemed fine on flat ground it seemed a little quicker. As soon as I took it offroad and attempted to climb my 1st hill the clutch slipped like crazy. I took it back to the place that did the work and they said that I had a flat spot on the belt and replaced it and charged me half price for a replacement belt. I took it out again today and the 1st hill I attempted to climb the belt started slipping again. I was in low gear and locked up. Any ideas what might be causing that would be appreciated. I called the outfit that did the work and they said to bring it back and they would look at it again, but needless to say I am a little nervous.
