Getrag 232 vs 245 output shafts

[Chris_B]

Does anyone know whether the Getrag 232 (02 4 speed) and the Getrag 245 ( E21 5 speed) have the same splines on the output shaft? I am installing a 5 speed conversion in my 02 and am faced with the 3 bolt output/input flange quandary with the drive shaft conversion. It would be great to be able to convert my 245 to a 4 bolt flange.

Pretty sure thats a no, splines are different.  Sorry.

There is this guy in Portugal selling these:

Somebody buy one of these and give us a review.

The 74-76 4 speed is actually a 242 which is slightly different from a 232 like the fine splines and better syncro's. These were also used in e21 320i's.

 

The part numbers for the output shafts are different so I'm guessing they aren't interchangeable.

 

If you need an output shaft for a 245 I have one available, pm about it

Nope, the 4 speed flanges are all different than the 5 speed version.

 

Which is a bummer, I agree.
