I don't see nothin' wrong... with a little bump and grind...
But for real though, people have had issues with the synchros in these cars. There are plenty of "grinds when going into X gear" threads to be found. Some people have had the dealer give them a new transmission, some have simply changed the trans fluid and the problem was resolved.
My car used to grind occasionally going from 4th to 5th if the revs were high, but it hasn't happened in a couple months. Not really sure why.
