As we whent further up the motorway another clinking noise was heard so I pulled of at the service area only to find that I could not get any gears [:0]. On investigation I found that the clutch selector arm in the gearbox has become detached inside the bell housing
Today I will be striping out the gearbox (rain permiting)to find out what the problem is.
Sunbeam Sam I will contact you about the wheels do to breakdown unable to collect them.
