Hi guys. My vette is giving me some issues and I’m sort of stumped on my next move here


My clutch won’t disengage with the car on. When it’s off it engages gear. When I turn the car on in gear I can smell the clutch.

I’ve bled the master and slave with a vacuum bleeder but it still feels like there’s air in the system.

When I bleed the system the car returns to normal. Butter smooth shifts. But after sitting for a day or two, turning the car on and shifting it will act fine until the issue returns. No leaks on the master, vacuum bleeder holds consistent pressure.

I noticed when bleeding the master side there were tons of tiny bubbles being sucked out. Should I just leave it connected to the vacuum bleeder for like 30 minutes or is there something else going on?

also when driving in the city I had my foot on the clutch, I felt the pressure change and could no longer disengage the clutch and shift out of gear with the car on. I had to turn it off. Shift into second and get it home

also I thought it was my shift collar clamp but that has been replaced with a new bolt. I’ve adjusted my Tmod shifter which seemed to resolve the issue initially. But I think the issue is elsewhere at this point

What else would you suggest to check?

08 z51 6spd
Clutch, throw out, master, trans fluid, tmod shifter, dot 4 fluid, shift collar clamp and bolt - all have been replaced

pedal has 1 inch of dead space with no resistance and then it feels consistent until the clutch disengages. Pedal returns normally on its own
