My stock clutch wore out after only 15,000 miles. Got it replaced under warranty. Have noticed lately that my shifting (especially from neutral to 1st and from 2nd to 3rd is not terribly smooth. Seems like a little catch before I can ram it into gear (worst from neutral to 1st). If the stock clutch is so weak, is it possible that my gearbox could also wear out? Or could it simply be my shifter? Anybody else had a similar problem?
