OK first of all i cant shift at/after 6k rpm. It doesnt grind or anything it just wont go into the next gear. Though anything under 6k its fine.

Also my clutch catches very low. I had a friend of my mine help me bleed the clutch(hes a mechanic) and to no avail its still catches very low. After my friend drove the car he said the clutch catches way to low, it feels spongy, and there is a little bit of play on the clutch. Also, to get a smooth shift u literally have to push the clutch all the way to the firewall. I had the master cylinder changed about a month ago, cause it use to leak from the inside and know its fine. Im thinking it cant be the slave cylinder cause it would leak to the ground which it doesnt. The Hydraulic fluid resivor doesnt leak, it stays stable. I have no clue wat the problem is..my friend says its the clutch going bad but i dont want to change the clutch till im sure thats the problem.

Any help will be aprecciated thanks.
