I'm driving since ten years manuals, I've got sports cars, and here there is one thing I am sure : it's absolutely not normal. I know how works modern transmissions : even when you push the lever very hard, the shift should not pass until the synchro are at the same speed than the gear. It's just that I can't understand how one day it can work, the day after it doesn't work anymore. The dealer also don't understand.

OK, @
lludo , so now we know the transmission is "broken in" and you are "broken in" (know how to shift a MT ....
).
So, I reckon a strategy for finding out what's wrong with the transmission would be to try to determine what is different from the times it works good and the times it doesn't work good..... ??
Like, maybe:
* transmission temperature?
* air temperature (air in the hydrolytic clutch lines)?
* road surface?
* payload?
* phase of the moon ......
OK, what I would do is to drain and replace the transmission oil (I wouldn't care what the previous owner
said). That, of course, will make sure the fluid level is up to full.
Next, I would drain and replace the clutch fluid and bleed the system (you may have air in the system).
You may wish to re-check the clutch adjustment.
So, if those things don't "fix" it, I reckon it's time for a new transmission (since people don't rebuild things anymore .....
).
I hope you get it sorted out.
