Default Need help diagnosing a shifting issue

To start, I've got a Tick M/C and a Monster level III clutch. I replaced the slave with the new unit that came with the monster package.

I've had a shifting issue for a while now. It's not much more than really notchy shifting, but here's the thing: I've experienced some really smooth shifting... but it doesn't last for long. I've bled and bled the hydraulics... then bled some more, and I've adjusted the master cylinder too, over and over.

When I adjust the M/C out the shifting gets extremely smooth, like no resistance smooth, but it only lasts for about a minute or so... about the time it takes for things to start to warm up. Now I've adjusted the M/C out to where it's out to the stock pedal height and I'm a little worried about adjusting it out any more. My pedal has some play in the top of it too, like the kind you get from air in the lines. I've checked for leaks and I can't find any (except for the leak in my last tick master which they replaced for free!).

Could it possibly be my slave?? If so its about a year old and has about 6k miles on it. This whole thing is getting old.

Still having problems. Anyone care to guess what's going on? I've got really notchy shifting and it's getting on my nerves, especially after investing in so much transmission stuff.

I think that T-56's are naturally "notchy" unless you get the MN12 with the different cones and junk in it...I wouldn't worry about it

T56's are notchy with stock hydraulics. With a tick master they get EXTREMELY smooth. One of the reasons that they are notchy is that the stock hydraulics don't release the clutch completely. The adjustable part of the tick allows you to adjust the amount of fluid to release the clutch. Tick recommends adjusting it out until it your shifting becomes smooth, but not to adjust it too far to avoid damaging your pressure plate.

My setup will stay smooth shifting for about 2 shifts worth, then it's back to being notchy. 5th gear also scrapes. When everything feels like it's shifting smooth (right after I adjust everything) then it shifts great. Actually, it shifts like a foreign car. It gets so smooth that you swear there isn't even any resistance when it goes into gear. I've also noticed that all the noise associated with the monster clutch goes away when things are working well... hydraulically.

I have a sneeking suspicion that it's my slave cylinder. I've bled these hydraulics until even a colonial American doctor would say that's enough.

Bump. I'm wondering if I need to adjust the master cylinder out some more? It seems scary to adjust it too much...
