New van It's done 9 k miles Gearbox has gone again. Synchro on reverse 2nd and 3rd has become stiff and difficult to engage. It was fully repaired at 5.5 k and it's gone again at 9k. Van has warranty untill Aug as I bought it new with ten miles but it was already a year old ( pre registered). I want the gearbox replacing. Can I demand it ?
