E46 5 Speed Manual Transmission Question ???

Hey

I will be replacing a clutch in my brothers 2000 328ci 5 speed, the trans in the coupe is slightly going out. I do have a low mileage manual trans from my old 323i 5 speed, was thinking if its the same or could work without any problems. It should bolt up without problems but what is the difference ? Anyone know ?

RealOEM shows that the model #'s are same just part # and supplement # is different.

323i trans info :

Rmfd-5 speed gearbox
S5D 250G - TAJT
23001434410

328ci trans info :

Rmfd-5 speed gearbox
S5D 320Z - THMW
23001434485

Can someone help me out ?

It will work but you would need the shifter, and driveshaft from the 323i as well.

That is a very good transmission, it can't just go out, you mean syncros are dead?

My synchros are bad in my 328. 4th to 3rd crunches. Haven't tried a fluid change yet

The 328ci has close to 175k miles and still running excellent other then it having stock clutch that is going out now. Well I still have all the parts from 323i so might consider swapping everything. The 323i currently has a s54.

I had that problem and fluid did wonders. I used redline and it was major upgrade

They are good transmissions, but they do fail. The transmission on my 323ci 5 speed was why I no longer own it. The bearings inside, for whatever reason, began to make a horrible noise. After Diagnostic at BMW and trying all the easy stuff, it was determined that one or more of the bearings in the tranny were gone. Luckily I got a great trade in value for it (feel bad since they didn't know about the issue, but its a large dealer so )

So its unlikely, but they CAN fail, even at 128k and with proper maintenance.

To the OP, to my understanding you would need the shifter assembly, and driveshaft to make it work. Should bolt right up to the engine and work from there. Good luck.

Okay I had a similar question. Say I took a 250g from a 03 325i and i wanted to put it into my 01 330ci. realoem says my car uses the 320z. Would this be okay for a 5 speed swap in my car? also another note, the tranny is 22 tooth. what parts would i need, ie which driveshaft, shift kit for what model, etc?
