I have to clear something up as well. So there are two models of Steptronic tranny available and the corresponding E46s.

A5S 360R GM 5

323i/Ci/Cic :6/98 to 3/00,323it:1/00 to 3/01,
328i/Ci/Cic:6/98 to 6/00,330Xi:from 6/00,
325Xi:from 9/00

A5S 325Z 5HP 19 ZF

323i/Ci/Cic :3/00 to 8/00,323it:from4/01,
330i/Ci/Cic:from 6/00,325i/Ci/Cic:from 9/00

A lot of people have disputed that the GM model is less than satisfactory compared to the ZF one. Fact is, the GM model is not a part that is taken off the shelves but a part BMW has modified. This is done through the GM Power Train Division of Strasbourg in France. Note that GM Europe and GM USA have very different design philosophies.
