While driving in my car one day I intended to shift into 3rd gear, but it only made a grinding noise. I can only assume since the noise persists even with rev matching that its a syncro/cone problem. I try to shift during the proper rpm area, and sometimes it will shift without a problem other times it grinds. I have no idea why. It had approximately 45,000 miles on it then, now around 70,000, still has the issue.
