T56 trouble shooting

[LS1 TA]

I recently took apart my tranny to figure out why 5th & 6th gear were not working. Other problems I had were that it was sometimes hard to get into gear and it felt at times that the clutch wasn't disigaging. When I tore it all apart I found that the little ears on the 5/6 gear shift for were gone and the fork was just moving over the syncro. I replaced the shift for and the clutch slave cylinder, as well as the input shaft bushing. 5/6 gear now work, but it is still hard to shift gears at high RPM's. Also at a stop, if you start to push it into first gear, the car will start to creep forward before its all the way in.(this only happens some of the time).
