Leak between trans and transfer case

I'm losing fluid between trans and transfer case on my 06 X3, e83. I was told there no gasket there, that it's just 2 machined part that fit snug. Is this true, and can it be fixed? My cell is 6103340165 if ANYONE can help asap please. Also, How do you drop or slide the transfer case back off the trans to see the problem?

There is an input shaft seal in the transfer case as well as an oring. If you go through the trouble to slide the transfer case off, you may as well replace them. To slide back the trasnfer case, you have to disconnect both propeller shafts drop the exhaust (I don't think you have to disconnect the exhaust from the downpipe.) It's then a matter of unbolting the 5 or so torx head bolts that hold the transfer case to the transmission.
