Spec 2+ not shifting at high RPMs
You can read about my install and first impressions and full set-up here
https://ls1tech.com/forums/manual-transmission/703978-spec-2-first-impressions-issues.html
Quick run down is Spec 2+, turned LS6 flywheel, 02 Hydralics(1000 miles on them), fresh tranny rebuild
Now the transmission is not wanting to shift at high RPMs.
The transmission is SILKY smooth with the car not running(fresh build) or even while stopped now. Once you start moving the clutch is a little notchy, but not too bad.
Once the rpms start to increase and you try to shift with ANY speed it is like it hits a WALL and you must keep pushing and it will finally go into the next gear. It is like it goes TO the gear, stops, then goes into it. I have a bad feeling that it is not releasing all the way still, but not sure. Any other ideas?
Thanks

Alot of t56's have problems with the clutch lines expanding over time. It may not be much but its still enough that when the clutch pedal is pressed the lines expand so full pressure isn't used to release the clutch. The clutch may not fully disengage because of this. I haven't got to it yet but i'm planning on swapping my stock lines with braided stainless steel lines to help it out. A buddy of mine did it to his lt1 T/A and he said it was like driving with a brand new clutch and tranny. You should be able to pick up the lines for it for under a hundred bucks.
Good luck on it.

master and slave have 1k miles on them. I have the drill mod. It has regular Dexron III in it.
It does it no matter what temperature.
I MAY try to bleed it some MORE. uggh....But Ive been through bleeding it a bunch....
