having followed mechanical (hard part) failure since day one,, and seeing the narrow cross section of them, I'll say most were '13 and up to '15,(after that point non reported); when the ratio on gear one changed.... that said, the gears, and clutch, are non -associated.. so far I have sen 6 reports of gear failure ( mechanical / broken), and none were clutch associated.. well, a couple were, but they were slamming gears down, without clutching. after that... all the proponents of clutch-less shift, and can pretty much eat horse hockey... I nver bused my clutches.. and when the H.P, overcame the level of that clutch, it was all my fault. C14, C10, both had bulletproof clutches...
bleed the sucker... and it will b fine
