Hello everyone. Today as I was merging onto the highway I went to shift from 3rd into 4th gear and the gear would not go in. It would just make a slight grinding noise and after several attempts it finally went in. Yes the car was under heavy acceleration but it should not have had this issue. The car was 2900 miles on it and I was completely pushing the clutch in. The vehicle also has a notchy-ness when it comes to going into 2nd gear. Anyone ever experience this issue? It's 2012 honda civic si coupe.
