JCL is right on the money with his explanation. You have 1 transfer case.
Transfer case
without x-drive: Dexron III ATF BMW p/n 83 22 9 407 858. $13.25 per liter. (See picture on the left)
Transfer case
with x-drive: BMW transfer case oil - TF 0870 p/n 83 22 0 397 244. $46.71 per liter. (The old p/n was 83 22 0 306 816) ) (See picture on the right)
Clear enough?
(Per the ETK BMW states that the Dexron III ATF is used in all THM-R 1 Type automatic transmissions, E.g. in the E34 and E36. Also to be used for: E53 up to 09/03 without X-Drive)
(Per the ETK BMW states that the Transfer Case Oil is used in BMW types E60/E61 and E90/E91/E92. Also for E83 and E53MU from production date February 2005)

I am reading that there is two transfer case, one transmission(obviously  ), and the X-Drive. I used D4ATF for my transmission and 75w90 for my real transfer case. I have not change oil for my front transfer case, I assume the same oil as real transfer case. What about my X-Drive module? Thanks X5 Meister in advance, as you've been very helpful all along! |
