99 civic si, jdm gsr, obd2 ls, just changed the tranny fluid because it was hard to shift, put syncromesh in it, now if i go over 5000 rpm i have no gears. it wont go into any gear, but if i turn the car off and back on it will shift fine as long as i dont hit vtec. i dont understand

 

nothing? hearing a noise when it wont let me in gear. throwout bearing?

 

awesome. everyone is so kind on here thanks for the help.
