I've had my gearbox looked at an apparently it's screwed. I'm looking to put another used one in it. It's a TDDi with the 6 speed in it, are there many variations of the 6 speed. Also I was told the Mondeo TDCi 6 speed gearbox is the same, anyone know of this is true? Also I'm in North London looking for the gearbox of anyone knows of any?
