Okay here's my problem... When shifting below 5000 rpm's everything is cool, smooth shifting and no complaints. When im driving my car hard or racing and i bring my rpm's to about 6.5 thousand thats when i experience problems. When I launch in first gear and plan to shift at about 6.7 thousand rpm's my gears will just grind and i have to take my foot off the clutch and then reapply it if i want it to go into second. I noticed this only happens when shifting from 1st gear to 2nd. After that I catch all gears? Whats the problem? Would this be a clutch problem or transmission? thanks guys...
