Dear All Seniors,Lately I discovered that while on slow drive (appr at 30 km/hr or in the parking lot), my car is producing some howling noise from the engine compartment. However, the noise dissapeared once my car goes once my car goes beyong 50 km/hr. I wonder if any of you guys have had encounter similar problems? Hopefully it's not the gearbox. Please advise. Thank you in advance..Oris318
