What's this "nochiness" in 3rd gear?

I have read in these forums about a "nochiness" feeling when shifting. It's that crunchy, clicky, resistance I get when when trying to change gears. It get worse with aggressive driving. When I get into gear it's as if I've pushed a new key into an old lock. Happens in all gears a bit, except maybe fifth. First gear nochiness has been described in these forums and the solution seems to be drop into second before going up into first. As my mechanic says (and stop me if you've heard this one) they all do that. But lately, third gear has developed a very specific notch. With a gentle shift it's barely detectable. But with a little hard driving, I have to push to get that gear in place, more so than the others. Anyone know what causes this? Is it a problem or a feature? I don't yet know enough about transmissions to understand what is going on.

Check your slave cylinder and see how much throw you are getting. Should be a healthy 1/2 inch throw as. I recall. I think your clutch hydraulics are talking to you.....

Hadn't thought about that.

That's a good start. Also make sure your clutch pedal is level with the brake. If it's low and can be pulled up level your clutch pivot weld has failed.

If that all looks okay, I'd just try a fluid change with one of the recommended gear oils. It could be low.

Also, update your TX lube to the appropriate Redline product. It makes quite a bit of difference in the quality of shifting.

Be sure you read the "First Gear Fix" thread. The one issue with idling in neutral is that as you push into first gear you will get that horrid crunch of a non-synchro mesh of just the first gear.

I still can't understand Alfa making the first gear different from all the others.

Thanks all for the suggestions. All mechanicals checked out. I did change the fluid (and cleaned out a bit of muck at the bottom of the reservoir) prior to driving to Montreal and that made a noticeable difference.

make sure the transmission output flange nut is tight, unfortunately to check you must remove the driveshaft
