Honestly I think it was worn out,but I have around 17,000 miles on mine,also I went a long time and never changed the rollers because I didn't know that I should.I started attemping to fix a dead spot I had at around 30-40 mph,before I did any mods and that progression lead me to here.As far as whether a new variator is necessary,well it probably depends on what your looking for,different people will give you different answers.
