I had the same problem. Bleed your clutch line on the slave cylinder. If your not sure how to do it, have someone do it for you, even if you pay them $20 or $40. Don't suck air back in the slave cylinder, because it will be hard to get out, unless you have a pressure bleeder. You can buy one at your local auto parts store and it comes with directions. This notchy feeling you're experiencing is little tiny air bubble in the slave cylinder, which isn't flowing smoothly. Mine has gone a way and boy does it shift good now (Like New).
