My Vitz - 2006 auto model is giving very high whistling sound. This sound resembles with "Phatti Hoi Dholki" ie Broken silencer sound and is very high on speed between 0 to 40. After 40 speed this sound vanishes and this sound is high on D gear and low on S gear.
Got silencer checked and its totally fine. The sound is probably a gear box issue, as when the car is in gear this sound comes and when gear is N - Neutral this sound vanishes. But i am not sure 100% that it is gear box issue only.
Do you have any clue how i can get rid of this unwanted sound and my mechanic is unable to understand the reason, so any good mechanic in Lahore for Vitz?, How much is the cost of changing gearbox?
