Could be anything....

Internal damage to trans
Dead Clutch FLuid or Faulty Slave
Worn clutch or pressure plate

Btw its a LS6 clutch, for those thinking maybe its a LS7, My LS6 had 40k on it, not much racing but dead fluid in the slave, a busted bleeder valve and hot spots on the flywheel and looks like it had warped.

Havok...The creep you are experiencing and the fact that it is hard to shift gears is an indication that you are seeing issues with release. You can start by checking the hydraulic fluid. What color is it? If it is discolored then you should flush and refill the system. It wouldn't hurt to use a higher boiling point fluid while you're at it. You should also wrap the hydraulic lines to help insulate them from heat.

If the fluid is not discolored then you should try bleeding the system. You need to be diligent when doing this as it can be a pain...but getting all the air out of the system can make all the difference. If this doesn't help then it is time to move on to replacing the hydraulic components (Slave and Master Cylinder). Let us know what you find and I will be happy to assists with trouble shooting from that point forward. Thanks!

Isaac, since when did you swap to a T-56? I'd try bleeding the hydraulics first. If that doesn't work, replace the master cylinder and see how it works.

I had a issue with a spec 3 like that, except after 850 miles, it wouldnt go into any gear period when it was running. Was a faulty pressure plate. Did you upgrade the slave?

Your clutch is dragging. Install adjustable master asap. This is a problem that many Tex clutches have....once thats fixed its an awesome clutch.

Plus 1. Put in an adjustable or do the adjustable mod in the stickies. I fyou drive it with the clutch dragging, you will wear out the teeth on the syncro side of first and reverse.
