Hi all
Today when I was driving with my windows down, I notice a chirping sound when I'm stopped at a light. But when I put it into park, it disappear. I cannot hear it when car is driving either. So in summary, the following situation makes the sound
Car stopped when in reverse or drive, but not in park.
Anyone knows what the reason would be?
Thanks in advance

I was thinking belt for a second, but then once I put the car in park, there is no noise anymore, that makes me worry if it is something related to transmission

You're not serious, right? I've yet to see an engine that uses a chain to drive the accessories instead of a belt.
When you put the car into D or R it's putting a bit of a load on the engine. The RPM's drop slightly. The belt could be chirping a bit under load. Does it behave the same way in N as it does P? How old is the belt? Also might check your idler pullies and tensioner pullies. A bearing in either of those on the way out could start out by chirping. Fortunately if you're a do-it-yourself type person, they're easily replaced and not too expensive to do so.
