Hey guys sorry for the newb questions in advance but this is my first iX so im doing a bit of learning, definitely not new to BMWs, just the awd ones lol. The question i have is what are the differences between the auto and manual transfer cases? I have a chance to get my hands on a transfer case from a auto iX and with really low miles on it for a really good price, so therefore i was wondering what the differences are and if its possible to use the auto transfer case in the a manual car with parts off the one currently in my car since its a manual, my tcase works awesome but i figure its not a bad idea to have a spare one on hand.

At the risk of being painfully obvious, one is for an automatic transmission and one is for a manual transmission. No, they are not interchangeable. The internals are the same but the cases are different to mate up to the specific transmission. If the VC (viscous coupling) is good in the auto one, hang on to it. Good VC's are hard to come by and are NLA from the factory.

The front case half and the input shaft. The manual has a seperae shaft, the auto is built into the tranny. Internally, they are the same, and you can build a manual one using parts from an automatic
I see so could you just unbolt the front half of a auto transfer case and bolt it on to a manual transfer case or vice verse?Current:1995 :540i--m60+6speed+bunch of other goodies(supercharged) hehe

"just unbolt the front half of a auto transfer case and bolt it on to a manual transfer case or vice verse"
not quite that easy as components stay attached to the front half of the case and will need to be removed and installed into the other front case half and there is a shim that has to be set up properly if case halves are changed, good time to change seals also
see group 27 (forward button) Transfer Box page 12 in this TIS for disassembly/reassembly

absolutely if you can get it cheap , you can tear it apart an learn how it works (i just got an Auto T-case for free ,just paid shipping, has bad VC but new chain/gears NLA, will rebuild VC ) especially if the VC is good which you can test off the car by locking one output and attempting to turn the other output it should be very hard if not impossible to turn if the VC is good. i have two spares now 1 man 1 auto
VC are the same Manual to Auto as are about 90% of internals
lots of good info on E30tech IX digest (not very active anymore) like this VC rebuild post

you and a bunch of fellow IX'er would like to know where there are good used working manual T-case's so your not alone in that search, unfortunately...(bit like unicorns now)
just keep your eye out in parts sources like craigslist ,wrecking yards , bmw digests like this . they come up for sale from time to time ,but unless you can actually drive/test the car its came out of there's no gaurantee it a working unit . you can bench test them too as i saidAngus
