Hi folks my family are a honda dealer in scotland. Your problem is the software to run the gears properly. Honda has introduced a software update that cures the problem . If not caught right away it damages the gearbox and will require a full strip down and rebuild. Honda should foit the bill for it. Getbto your dealer and get the software update done asap. It can be done in your garage home work or farm. Like i said if not caught quick enough and up dated damage will be done. Good luck guys and hope this helps.
