Hi all, realize this bit of the forum is for Seicentos and Cinqs, but some of you lot might be able to help me with this one.

My 1.1 Punto needs a new gearbox asap, I have found a box from a 1.1 Seicento that is local and at a good price. I've had a search on here but cant seem to find anything properly conclusive as to what I'm after.

Question is, can I go ahead and buy it and put it on the Punto? The casings are the same I know that, and I'm not worried about any issues with the gear ratios etc, the car just needs to get me to work and back over the winter.

What I need to know is this "new" box has a cable clutch and the Punto is hydraulic, can they be swapped? I know I can swap the clutch arms over, the cylinder itself is what I need to know about, the Seicento one seems to not have the holes needed to mount it. Can I swap over the entire gear change mech on the top of the box from my old one to let me use the holes from this?

Thanks in advance. Charlie.
 
Some boxes aren't interchangeable - I went through this a few years ago. The gearbox mounting points on some don't line up (the centos have two different mounting brackets - I'm guessing Puntos do as well). Had one that wouldn't line up properly on the bell housing to the block either but that was easily fixed by swapping the bell housing. The third box proved to be the right one for fit (the vendor was getting a bit pissed off by this point so just as well) but had a cracked diff housing - easily fixed by creating a frankenstein box from the others I'd been sent.

If all the mounting points do line up then it is just a case of swapping the arm and the gear change unit on top of the box.
 
AFAIK, all 1108 boxes will mate with the engine. 899 boxes simply won't. The 899 was not a FIRE engine.

BUT some 1108 Seis (and I was forgetting this) came with what seem to be 899 gearboxes with a different belhousing (to fit the FIRE engine). These have wet inner driveshaft joints and -- assuming that all Puntos have dry inner joints, obviously won't do the job.

You may find that, given dry inner CV joints, you have to swap the cups over to suit the Punto driveshafts, which may have a different O/D. No big deal, but do it one at a time to avoid the diff slipping into the gearbox casing.

The numbers stamped on the front face of the boxes are useful. AFAIK, they can only be C.501.5.1 for the 899 type or C.514.5.10 (the dry inner CV joint 1108 type). You want the C.514 type, unless I'm badly mistaken.
