Losing power going uphill on long mway drag. Went from doing 85 to 50 with HDC light coming on. pulled into h/shoulder, turned engine off then on to find warning light gone off. Set off but very little power. On flat & down hill no issues. round town ok but slips going from 3 to 4, then again 4 to 5....with massive revs then loss of power. Garage where purchased vehicle have said that due to 105K mileage gbox could go at anytime, dealer took it for a run and said it is shot and recommend go to Trading Standards.....dealer wouldnt offer warranty due to mileage but has offered to get recon in for £980 (he is not charging for fitting and offsetting VAT through his business also offering me use of runabout whilst it gets sorted.....do I just bit the bullet and let him get on with it or take the long term option of Consumer rights route??
