I had this happen a couple times coming to a stop, it felt like the clutch never disengaged. my friends have had the same clutch problem too. seemed to get alittle better when I went to synthetic oil but I doubt that has anything to do with it. Im wondering if the neutraling problem alot of people have is related to the clutch not disengaging on the 1-2 upshift causing it to just go into neutral, just a thought.
