I have an 2013 Hyundai I20 1.4 diesel engine with 6 speed. When changing down or up to 3rd gear its making a griding noise. Do I need a new gearbox.
Hi Richard,
Not necessarily. It might be a clutch issue, or a gear linkage issue, which (hopefully) are a lot less expensive to fix. It is, however, impossible to diagnose such a thing from afar. I suggest you bring the car to a good mechanic to have it looked at.
