That's wrong and not an answer to what I asked. (archive)

The bell housing bolt patterns of the small six and four cyl. are not the same. You can't just take the 245 tranny from a 320i and bolt it to a 323i engine. Here is what I am asking.

1. Other than the bell housing bolt pattern and bell housing shape, is the 242 tranny for a 323i and for a 320i identical internally and externally?

2. Is a 245 tranny a 242 tranny with an intermediate section added to accomodate the 5th gear parts (as it appears to be in pictures)?

3. Would it be feasible to take the front section of a 323i's 242 tranny and combine it with the intermediate and aft sections of a 320i's 245 tranny to create a 323i 245 tranny?

This could be easier than finding an original 323i five-speed tranny and not involve messing around with electronic pick-ups and speedo conversions.

You could. Both bolt patterns are the same, so you could just bolt the 245 in place of the 242. You will need a shorter driveshaft, though (39mm I think).
