Scary whine when the engine is cold

Hello guys! I just bought my first Jaguar. A 2004 X Type with a 2 liter V6.
Great car, however, it's making a whining sound while accelerating. Really loud when the engine is cold. As soon as I start the car and rev it, there is no sound whatsoever. But, if I shift into Drive or Reverse, and back into park and rev it, it whines. That's it. I don't even have to move the car. Won't make a sound until I shift into a gear, but after I shift, it whines continuously with the RPM. It's a fairly loud groaning whine. Kind of scary.
It quiets down when warmed up. But it's still noticable. I googled a bit and found out that it could be the transfer case, but my car, being FWD, doesn't have a transfer case. Pretty confused right now.
I took a quick video and uploaded it on YouTube. Please have a listen.
Any ideas?
Thanks!

Thanks for the replies! I tried the search criteria, got results, but only found one video, and that was about a constant rattle.
If it is a heat shield, how can the pitch change with engine RPM?
This only happens when revving the engine. When I started the car and revved it, it didn't make a sound. I then shifted into D and kept it for 2 seconds, then to R, again for 2 seconds, and then shifted back to P. Revved it, THATS when the whine started! I didnt move the car, Just kept my foot on the brake and shifted to D and back.
Heres a video I took while revving, right after starting the car.
And heres a video I took while revving, after shifting to D and back.
So, no whine until I shift into a gear and back to Park. It can't be the gearbox because its fully disengaged when in Park, right?

i can only lead you to the water.
im not a physics scolar so i cannot explain the hows and whys of your noise.
what i can say is that you have the classic sound and symptoms of what i have suggested is the cause.
your 2nd post only confirms this more.
feel free to look for other causes... perhaps try the chevy forum... lol

Sorry for the late reply guys. Was a little busy yesterday. Alright. You guys are the experts, and that's why I came here. If that's what you guys say, then that's what I will check ![Smile](https://www.jaguarforums.com/forum/images/smilies/smile.gif)
I was skeptical because it doesn't make a sound until I shift into a gear.
I'll get this baby up on a hoist ASAP and give you guys an update.
Thanks a lot for helping me out!
