Weird noise in '09 XRS A/T

I have a '09 XRS automatic, 15,900 miles (25,588 km). A few days ago I started to notice a weird noise only when changing from D to N.

The sound is low, like a double whistle. It happens after using the car for a while, so the tranny is normally hot. After completely stopping, when changing from D to N (no hand brake applied at this moment), the sound happens. If I change again from N to D, and D to N, like 3 more times, the sound get progressively lower until is gone. It doesn't happen when changing from/to other gears, only from D to N.

However, for normal operation, it's a blast, it shifts when it supposed to, fast engagement between gears, no weird sounds when shifting. If I floor the pedal, the tranny will downshift quickly and then if I depress it, it upshift quickly. No change in this area since I bought the car. Even, when the engine is cold, the engagement in gears is still normal.

Anybody had this experience or a similar one? I did the 15,000 miles maintenance and everything is fine, no engine light since I bought it.

Do you think that changing the tranny oil at this point may help? This is something that I was planning to do.

Thanks in advance.

aside of this noise..what else are you experiencing? when you drive the vehicle, does the car jerk as you hit the gas..do the rpms seem higher than usual?

i think your pressing on the gears too hard going from d to n and then p..but i dont know just my opinion

Thanks for the reply.

No, the car doesn't jerk when I hit the gas, the rpms are fine as usual, nothing wrong here.

What do you mean on pressing too hard on the gears when going from d to n? When I completely stop to park or turn off the engine, I keep pressing the brake pedal, then change from D to N (when the low noise happens after driving for a while), then to R, then to P, then apply the hand brake.
