99h22ek

so i took the h22civic to the track the other week. I passed 5 times and not once did 3rd work for me. I was shifting (not power) at roughly 8000. 1st and 2nd are usually great. each time when i went into third gear the car acted like it was in neutral. id matt the throttle and the rpms just flew up and the car didnt go. each time i had to wait til the rpms came down to like 5000 for the car to go. its almost like i'll release the clutch but it feels like the clutch pedal is still completely down. ONLY HAPPENS IN 3RD GEAR. anyone?
