Grinding Gears

I was recently out where all the imports hang out around this area, and when I was leaving I got a little crazy. I pulled out and spun 1st and 2nd then calmed down. At the next light I accelerated normally and when I went into third gear it grinded a little. This makes racing impossible. After driving slowly for a few weeks it went away, but it still does it on occation. Anyone with suggestions please help. Much appreciated.

Syncros, it’s gotta be

Transmission fluid change. Make sure you change to a good, quality brand. Try this first, as it is the cheapest and - most often - the first remedy to a grinding gear.
