.Anyway the gearbox is giving me some problems and need some advice as to what the problem might be please.Today was driving her and every tI'me I change gears on the 4 speed box when releasing the clutch I get a clunk noise as I'm releasing the clutch half way and another noise when I release the clutch full into the gear.Also when i release the accelerator in a gear at a low rev it has a clunk noise with a like kick back feel.The shifter is pretty loose to. Please help..
