I think there was an initial design issue with the oil level. This was fixed by increasing th level, but this means you can't check the level without draining the 'box. This may have resulted in failures due to leaks or incorrect maintenance. There also seems to have been issues with specific batche or make of bearings. Not withstanding these issues, there does not seem to be a fundamental issue with the M32.

I would to an extent [and very respectfully] disagree.

I know you've said the above before and I think I disagreed then too. I see your point that for the number of units out there it's very probably the case that the % failure rate is really quite small.

The problem is that manual boxes particularly are a very solid and reliable device; the design has been really rather well perfected over the years, so when you start to see the failure rates that the M32 boxes have experienced it stands out, even if it is a fairly small number.

I would suggest even the fact that people know about it enough to be having a serious forum debate about the matter is evidence enough that there is something of a problem with the M32, even if it is something as simple as the oil level being too low.

I would add for the record that I had an Alfa 159, 1.9 JTDm, which did have the M32 in it. I had the oil in the box changed and overfilled slightly (cant remember specifics these days) to prevent any issues. It never had an issue or even suggested it might be starting with an issue though, it was purely precautionary.

Re: Multijet 150 - looking for full induction / cold air intake??

If you're referring to the 2.4 JTDm certainly from my Alfa experience they don't run the M32 on those. Only the 1.9 JTDm. The 2.4s used to run F40 boxes I'm sure. That might have been the early 2.4 175bhp models in the 156 though. Whether that changed with the later variants (200bhp, 210bhp) found in the 159, Brera, Spider, I don't know.

You are correct, I must have been asleep. The 2.4 was only available with the
Aisin AF40-6 automatic gearbox.
