How About Bleeding The Clutch?
I wonder if some of this notchy shifting could be caused by air in the lines. Would bleeding the clutch be a remedy for this problem? The transmission has been rebuilt, new master cylinder, and a lot of adjusting the shifter, and just can't get it to perform the way it should. The shifting is harder at high RPMS. The car has a 408 and turns up to 6600 RPMS. I had a stock C5 before and it shifted fine. I've got to get this corrected. I'm ready to make some passes, but am missing 3rd gear quite a bit. Please let me know what you think.

The transmission only has about 200 miles on rebuild, and it has redline synchromesh in it.
There was an adjustable master in it that had about 1 1/2" of play at the top which would pump up tight while tapping on the peddle. We replaced it w/ a stock master. It has no play but a bit spongy at the top. I noticed while doing a search, someone said the peddle should be rock hard at the top. Would this be a symptom of needing to bleed the system. Thanks a lot. I really need to get to the bottom of this

Putting a washer on the shift detent bolt might help some. Not sure what to think about it being harder to shift at higher rpms though. Hope the synchros are ok. The clutch pedal should have some play at the top, but shouldn't pump up by tapping. If it pumps up, you have air in the line. Is the fluid clear?

When you bleed it, make sure you have the rear of the car a little higher than the front, the bleeder is in the back of the slave, so tilting the back up will ensure that you get all of the air. If you have small hands, you can bleed it without removing the exhaust (unless you have long tube headers) or tunnel plate.

Just talked w/ Jared from textralia and he said that I probably ruined the clutch by using an adjustable m/c. He said to call back Monday, and he would see about taking care of the clutch under warranty. This will be my second dealing w/ this guy on a clutch warranty. This company has to have the best customer services I've experienced.

Usually when the clutch is the cause of problem with clunky shifting it's because it's not fully releasing. When you changed out the hydraulics and bled them it should have been fine if it was fine from the get go. Unless something is wrong with the clutch disk itself, but I don't see how an adj. master could have caused that issue.
It's Textralia's clutch, so they know there setup best. See what they can do for you. Good luck.
If you have any questions just shoot me a PM. I'm always here to help when I can.

The theory is that the adjustable master pushes more volume through the hydraulics which cause over travel for the pressure plate. The damage is supposedly caused by the fingers being hyper extended and bent. I don't know, and was kind of questioning this idea myself. Thats why I called Textralia. The rep sounded confidant in saying it probably ruined the clutch. I really appreciate your chiming in on this. Maybe we can all learn a little something. I'm starting to feel a little over educated at the moment. These lessons aren't cheap.
TEXTRALIA HAS EXCELLENT CUSTOMER SERVICE!

If the clutch did not show this problem from day one, then that would point to Textralia being correct. If it was like that from day one then it would probably not be the case or the other possibility is the clutch was deffective since day 1. For right now I would do what they suggest. They seem to be a stand up vendor.
I haven't seen an adj. master cause that problem on other clutches so this would be a first.

i am having a very similar problem with the C5 i bought this past week. Very notchy and hard to shift at higher RPMs and mine rattles badly if you give it any gas when letting off the clutch from a dead stop.
Mine also has an aftermarket clutch although the previous owner doesn't know what brand it is.
Please keep us informed on what you find out with yours!

I've had clutch problems since CAMS did a install and put that stupid *** adjustable m/c in my car. The bolts backed out of the pressure plate from their install which never worked right anyway. We replaced the clutch w/ a Tex. and used the same master. The shifting has always been a little crappy, and was always attributed to the sifter. We adjusted and messed around until we are now thinking Textralia is right. The problem seems to have been there from the beginning.

I had read over on LS1tech that using anything other than the stock m/c was causing problems with the Tex setup. If I remember right, one guy said he put the stock Z06 m/c back in and it worked great. I don't remember if the adj m/c was a McLeod or Ram but the Tex clutch setup did not like them. You might go over to LS1tech.com and them drop down to "Manual Transmission" and do a search. Lots of info over there.
