2006 325xi Transfer Case Problems

Hi All,
This is my first post here but I have been digging through the forums for all the info on this I could find.
I have a 2006 325xi Wagon which is now at 119k developing transfer case problems. There are no error codes yet just a whine that is following the RPM's. Thankfully it has not yet developed into a driveablity problem. I took it to my local BMW specialist and he's verified it is the transfer case and he'll only replace it with new or rebuilt parts and says labor is about 5 hours.
I understand the transfer case, the ATC-300 which I believe is the same for the X3, is $2500 from the dealers or I can buy used ones anywhere from $650-$1250 depending on the mileage thats on them. What I would really like to do is find a good transmission place that could rebuild mine, I've seen rebuild kits online for around $400-$500.
But then I've also seen advice on the from from users saying these can't be rebuilt. Though I have found some places that sell the parts for them as well as BMW service manuals detailing how to rebuild them.
Have others dealt with the same issue and been able to have their rebuilt or just gone with new parts? And the then what has proven to be the hardest so far is find a shop that's willing to do a rebuild.
Any help or advice would be greatly appreciated.

What's the fluid level?

Do the cheap stuff first. Fresh fluid.

The fluid is good, I forgot to mention that the actuator motor was replaced about 3 months ago. The fluid was changed at that time.
Also I say this is a transfer case problem because that is what the shop that looked at it said. So far all that the car does is the whine noise I was talking about. I've been calling shops and some guys are helpful and one said he didn't thing it was the TC as he's not heard of them making any noise I'm describing. He thinks it may simply be the transmission, at this point I really don't know.

I will make you a bet that they put the wrong fluid in the transfer case. You CANNOT use anything but what BMW supplies. I would suggest as a measure to save things before they get out of hand to request they change the transfer case fluid and make them show you the fluid from BMW they are using.

This is the only fluid that will work

Transmission fluid - BMW Genuine Transfer Case Fluid - Part number 83 22 0 397 244
Is this what they put in?

Good vid, thanks for the link.
As I mentioned the transfer case motor has already been replaced as well as the fluid at that time some 3 months ago. Its plastic gear was in good shape but the teeth on the end of the motor where all worn down.
Now the frequency of fluid changes on the TC prior when I got the car at 104k, well I have no idea.

I have no idea what fluid they did or did not put in as this was some 3 months ago. The garage specializes in BMW's so I would like to think they did the right service.
