it could be a couple things, have u made sure there was no air in the system, it could be the slave cylinder, but start with the cheapest solution first, bleed the system, then check the slave and master, then check the disk and pressure plate, some of the hard shifts could be causeed(very little, you still have a problem other than is)from it being cold out and just not shifting smooth untill it warms up, mine is like that, hard shifts when its cold, but not anything like u explained...hope this helped
