Is this really a good transmission for a 240Z?

never mind, I found info that shows it can be done but requires some customizing.

The 240SX tranny is "clocked" wrong for a L series motor.But all it takes to fix that is the bell/front case from a L series tranny.

So a 240sx trans can be used on an L24 in a 72, as long as I swap the bellhousings?

Yes it can.

Off the top of my head:

1) Bellhousing from a 280Z/ZX 5-speed must be used.

2) Front bearing must be swapped (bearing on 240sx is too large)

3) Shift rod holes must be enlarged in the bellhousing

4) 240sx trans is longer and requires crossmember to be modified

5) Driveshaft must be shortened

6) Shifter is further back. Console may need to be cut. Can't remember which years have trouble with this.

7) Some have an electronic speedo gear. Don't know how to get around that.

I'm rebuilding a 89 240SX transmission right now. The machining for the larger CS bearing and milling the face for clearance is simple as is reaming the hole for the larger fork rod. The shifter is located 2" further back than the earlier 5 speeds. In my mind there are several options to work around this. I haven't gotten far enough to be concerned about that, the transmission crossmember or driveshaft. These things will work themselves out though. The only thing I have not looked heavily into is the speedo drive gear. The 240SX housing (electronic VSS) is the same size as a 280ZX housing. The driven (plastic) gear is larger in the 240SX and the drive (plastic) gear on the output shaft is also larger. I don't know if the 280ZX gear will engage properly once the housing is installed and properly rotated for the retainer and bolt. I must assume that others have done this with success. It would be nice to have more info here for those having gone before.
