My X is close to 85,000 and I just got it about 3 weeks ago. Everything is fine and I would like to change out the Transfer Case fluid and the front and rear differ fluid. I called the dealer for the Transfer Case fluid and the guy said there are two types of Transfer Case one using Dexron 3 and other X-drive using the BMW special fluid. He told me to look at the Transfer Case for the indication but all I'm seeing is series of codes they are:
2710-7 515 748.0
SPT LWX 1220800 0067504
09-04-03

Can somebody help me on which fluid my Transfer Case is using. My last 7 digits of the VIN is LH47314 also how many qt does each diff required.
