Yep my gearbox has gone and my clutch was also slipping previous (on 30k not remapped!) . Vauxhall are replacing the box and have said they'll do a clutch for £300.
Courtenay Sports uprated one is only £195, so i'm thinking of getting this.
Is it worth getting or should i invest more and get the seemingly popular Helix one for i think bout 400 quid?
