Fault code P0730
P0730: incorrect gear ratio
P0730 means the control unit has compared the gearbox's input and output speeds and they don't match the gear it has selected. In plain terms, something inside is slipping or not engaging as it should.
Can I still drive it?
Keep driving to an absolute minimum. A slipping gearbox wears quickly, and catching it early is often the difference between a repair and a rebuild.
