The plastic thing that one of the cables bolts on to on top of the gearbox has snapped! I did have a problem a couple of months ago where this cable disconnected itself from the selector and I had to tighten the nut up again but this time the whole thing has sheared off! Anyone had this problem? The result is that you can't get 1st or 2nd, 1st becomes 3rd because lateral movement of the stick has no effect. I guess I can get a replacement plastic bit, dealer only? Anyone know how much it is and how to disconnect the cable from the old (snapped) one? Thanks.
