I had bought the Hyundai Accent/Verna 1.6L Petrol Auto Transmission (top petrol variant) a year ago. After 2 months or so, at startup and engine off, a loud creaking sound comes into play for 3-4 seconds from the mid dashboard (probably near the AC vents) and it stops. I showed this to Hyundai workshop and they say that it is always present in all the Automatic Transmission models of any make or model. Is this true? Please help me out.

Do take a closer look..
