When i put 2nd gear fast and at high revs, it scratches, if i wait to revs come down a bit it gets in smoothly. I suppose thats the synchronizer "brake" right? So, im planning on changing it, and if its not that expensive, change all of them.
But, are they sold sepparately? Or I have to change the whole Synchro? And where can i get them? Thanks!

Yes, you're correct, the synchro will be at fault. Yes

Most transmission specialists would be able to do it/source the part I would have thought.

I have just changed the gearbox oil, and miraculously, the scratching on 2nd gear is gone!!!
When I drained the gearbox, the oil that came out looked like grey mud!! And the smell was unbearable!!!
Now the gearbox runs really smooth!! It´s a completely different car now

I was going to suggest you try this first. Very occasionally, this does work.

In the majority of cases though, it's synchro replacement time.
Glad it's sorted. Smile

I've also had cases where sloppy warn linkages don't push the selector levers at a decent enough angle so they grind at high revs. First thing to try is box oil though but chances are the synchro on second is getting tired.

Yes, probably this wont last long, but the problem is "temporarily fixed".
I bought the steel gear linkage kit and the short shift from pug1off also. I hope this also help, cause the stick has a little free play
