[ALFA33boxer]

Hello to all you Alfa maniacs!
I just prepared my little 33 for the summer and changed filters, oil (Selenia 10w40) and spark plugs (BERU 4 electrodes).
After…, the car runs smother, feels lighter, accelerates better, has a better fuel burning and normally the fuel consumption has gone down.
But after all this I got a problem, a problem that is making me suffer a lot in traffic. Sometimes is impossible to put the first gear in… (God, I hate when the gear makes that noise…). Sometimes is just fine. I have the same problem when shifting down the gears specially the 3d gear is impossible to put in going back from the 4th!!!??? It doesn’t have problems when shifting up.
So, where is the problem in my 33, what do you think?

thanks in advance
best,
Elvis
