I'm pretty sure you need at least a different length driveshaft. It's been done. Search for 'swap' in the thread title using advanced search.

...and I'm sure you know, but realoem.com newtis.info fcpeuro.com are all well-used sites that can help.

Really?I

You have an automatic '99 328i and you want to swap in a MANUAL trans from a 325i?

This is called a manual swap. It's quite involved..mechanical, electrical, & coding.

Have a search.

I would also suggest you put a topic in your post titles...Not help

New driveshaft, coding, decent amount of labor involved. And if yoy dont swap the gears in the diff, it will suck driving the car.

Find one from a 328. You'll need to do coding and get a new diff to match the new ratio of the transmission

well i wouldn't say a diff change is "needed" per se. nor would i say "it would suck" with a 3.46. especially since the 323Cic, 323iT, 325Cic and 325iT all come from the factory with the 3.46 with the five speed manuals.
also a lot of performance oriented 323, 325, 328, 330 owners swap the 3.46 in their manuals for more pep.

but agreed it may not be desired by some and a good point of things to consider in the swap. :thumbup:
