i'm planning to do a m30 swap into an e30, eventually. i currently have a 528e, my question was whether my transmission is the same as the one that came in the 535i cars. thanks

IIRC, it will not be the same. 528es had the M20 "small six" engine, with a different tranny than the 535s.

the gearbox is identical, but it wont work. the input shaft and/or the bellhousing bolt-patterns are incompatible.

alright thanks, pretty much what i was looking for.
does anyone know the actual tranny designation code for the 528e then?

realoem shows two different part numbers.

the M30 being designated 260/6 and the M20 piece being designated 260/5...

so maybe I was right.

Right, thanks. The 533 and 528 use the Getrag 260/5. However, the bellhousings are different between the two and do not interchange. If I'm wrong though, someone please correct me.
