I have a Cuore Dec 2006:30,000 KM 5 speed MT car, lately I have been hearing this tick tick sound from the cars gear - the cycle of the sound has been increasing lately. I had it checked at the dealership and they said it comes from every Cuore. I had the pressure plates changed as they suggested but the sound still remains. This sound only occurs when the car is in nuteral, if I would press the clutch it would vanish. I had some friend advised me to increase the gear oil by 1 ltr and the sound would vanish or should I have the gear changed? Can it be a problem with the clutch plate?
