I noticed you mentioned on another thread that your gears crunch alot. I have a CUP also and mine crunches going into 5th (no other gear). At first is was if the revs were over 3k rpm when you slipped it into 5th it would crunch. It has improved a bit now I have done just shy of 2k miles but it still does it on occasion when I am giving it a bit of stick. The only way to stop it happening is to wait for the revs to drop with the clutch down before puting it into 5th (Changing gear like grandma). Renault said give it a bit mor time as it will probably settle down as they can see nothing wrong with it. Is it me or are Renault staff very thick ?
