Whats the official correct transfer case fluid for a xi?

[maxt]

I havent been able to find an actual fluid spec from BMW anywhere in my owner's manual or online. Is it the same stuff as in the transmission (ATF)?

i think the transfer case holds atf. i used to have a 4matic mb, and the transfer case had the automatic tranny fluid in it, so i'm assuming bmw too uses atf in their transfer case.

It's MTF-LT fluid....it's a light weight gear oil (specifically 75W-80)...your car uses a whopping 1/3 qt....BMW p/n 83 22 9 408 942, unfortunately BMW doesn't sell it by the qt..some do but you will have to bring in your own container and they will fill you up from a 55 gal container...they like to charge allot for this stuff...I've heard in the $20 range...

so since the manual gearbox calls for ATF.... Can I get away and put ATF in there?

The ATF in the manual gearbox is much lighter/thinner than 75W-80.
You might be able to get away with some high-quality synthetic 75W-90 gear oil, such as Royal Purple Max Gear or Redline.

HOW DO U PUT? THERE IS A DRAIN PLUG ON THE BOTTOM AND A REFIL ON THE OTHER SIDE ON TOP? HOW MUCH U PUT OF Royal Purple Max Gear IN THE GEAR BOX?

Fill until the fluid comes dripping back out.

Only if you want to buy a new transfer case soon. Why would you want to put the wrong fluid in there after we tell you what the correct fluid is?

Yes it can use Red Line D4 ATF I have had this in my car for about two years now but im gonna switch to a closer to spec oem type fluid which is the Redline MTL (70W80 GL-4 Gear Oil)

Fill plug is on the back side top and drian is on the front bottom.
