ok, has anyone had this problem? My evo sifts fine but last night i gave it some power and shifted at higher RPMS. I was shifting at about 5000-6000 rpms which was fine from first to second then to third but when i shifted to fourth even though the clutch was fully in the gear grind but still went into fourth. If the car is at or below 4000 rpm then this does not happen. And only from 3-4 gears. Anyone elese have trouble like this, I'm still under warranty but i kinda want to know what it really is before the dealership tells me.

 

might be the synchro

 

i thought that but i really didn't know for sure. I know that they are a common problem with evos.
