Have got a 13/60 which is used regularly throughout the year (albeit only c. fortnightly in winter, weather permitting). No previous problems with gearbox/selection, but it has been stood for last 5 weeks due to mix of holiday/inclement weather so was looking forward to getting out at weekend but couldn't get into any gears easily except by double declutching. Only moved car backwards and forwards on the drive as didn't want to risk on public roads! Bemused how a problem has just appeared from nowhere - any ideas what might have happened and any obvious and simple fix? As said already there has been absolutely no sign of any gradual deterioration!
Thanks in anticipation
