Budding Enthusiast. 4. Name: Stuart. Ford Model: Ford Focus 1.6 Zetec. Ford Year: 2003. UK/Ireland Location: Cheshire. Posted April 24, 2013. Ever since I bought my 2003 Focus 1.6 Zetec, its had quite a stiff gearbox. There is very little movement when its in neutral and at times I struggle getting it into the correct gear. I was hoping to have the oil changed to try to help muffle the sound of a quite clunky and slightly rattly gear change. At lower speeds, when changing from second to third, and third to fourth it always makes a slight clunk when releasing the clutch pedal. The noise is from the gearbox. Mi0s8D.
