I was a little harsh doing some overtaking in 3rd gear this morning.
I have noticed a notchy feeling selecting gears and 4th was a little troublesome a week ago. I hit over 6k revs in 3rd and when I went to change up I couldnt select 4th at all for rest of journey. Is this overheating or just swarf build up? I suppose I can drive without 4th gear for now.. lol

Did exactly the same thing and needed a recon box, hope yours isn't as serious.
4th is dead as a dodo, well completely locked out can;t select at all :(

Did you have to change the box out or remove, fix and refit?

had a looksy on ebay for gearboxes, probably going to cost in excess of £300 for a box + fitting (anything upto £300/400 ?) :(

I know an alfa specialist around here who can fix it....

Ask a specialist near you how they would go about fixing it - if they mention machining the selector shaft you should be on to a winner - its still quite expensive as you have to take the box out..

Why is this? Can you explain the problem?

It may well be something simple like a linkage as Alfie suggested but if the box has to come out, by the time you've taken it apart, found out what it was, and replaced the broken bits, it's easier to replace the whole box with a second hand one. A good opportunity to add a new clutch while you're at it. This is the route my mechanic went with anyway.
Best get it over to a decent indie for a check up, you can drive it without 4th after all.
Good luck.

Hopefully this isn't too much like Chinese whispers but as I recall it told to me:

The steel shaft slides in the alloy casing. They expand at different rates when warm and the steel shaft chews into the alloy creating the swarf. Getting rid of the swarf could fix it for a long while (in my case this only worked for a few months) - having the shaft machined seems to be a permanent fix. (don't ask me how - apparently Alfa have produced a modified shaft themselves).

The cost is in taking the gearbox off - getting at and machining the shaft doesn't seem to be too labour intensive for someone who knows what they're doing.

Just to fill you in I did have this problem before as well, it was fixed along with a service at a main dealer, which was back in Oct 2007. It said on receipt removal and refitting of gearbox, so I assume they used the longer route than the guide on Alfaworkshops website. They charged well over £400 labour for it.

So I am vaguely familiar with the problem from before, but last time I remember it was more intermittent (and combined with knackered clutch), this time it just seems 4th is impossible to select, fullstop. The clutch operation is ok, and it should be seeing as it was only replaced last July.

If from what I gather it is just the swarf issue again, then hopefully I wont need a new box. I'm just trying to guage whether or not a new gearbox is the best solution in conjunction with the permanent fix daveypark has mentioned, or if I can happily get away with fixing the current box. The car has done just under 64k miles.

Miraculously fixed itself today, now I have a 4th gear ! :cheese:

Alfa gremlins or what. I think i'll be taking a it a little easier on the revs for now. At least this gives me some breathing room to save for the box out job in the not to distant future.
