I'm CERTAIN the automatic has different final drive ration than the stick on the 323i. In fact, I'm almost certain the 323i stick has 3.16 final drive and the auto is a 3.46. The wagon is like 4.0 or something.

dunno about the 328i.

From the 2000 E46 brochures:
(same for respective Ci and i)
323MT: 3.07
323AT: 3.46
328MT: 2.93
328AT: 3.46

Note that the AT trannys have the same ratios but MTs have slightly different ones (ZF vs Getrag tranny)

There could have been mid-production changes that aren't documented in my brochures. The 325iT MT went from 3.15 to 3.46 around April '01 production.
