ok when i am at the track or on the street racing and shift from 1st to 2nd it grinds trying to go to 2nd but it not even go in. i dont keep trying to put it in. when it does it i just push the clutch in for a little longer then it goes right in. but on everyday driving it shift into 2nd just fine. i dont know if it is the clutch or transmission. maybe i shifting to fast but i dont know.

 

warranty work. get your stocker tune back on first.
