New Clutch Installed, Now Won’t Go Easily Into Gear At Start-Up

[bnight]

My Gt500 pulled this, after pumping the pedal about a thousand times and vacuum bleeding it a dozen more, it would still go into gear hard in the mornings. I would start it in gear and it would try to creep. It eventually went away with more vacuum bleeding and use. I wouldn't take it back apart just yet. This is one of the many issues with hydraulic clutches, air bubbles, difficult to power shift, no adjustability. Clutch activation technology was at its zenith with the quadrant style cable clutches of the 90s.

My Clutch does this after 2-3 track days when there is too much air from overheating the brakes usually a fluid change gets rid of it.

I tried leaving the clutch depressed with the drivers side elevated over night then pumped the clutch a couple hundred times to no avail. It's been about 1k miles since clutch swap. Drives fine otherwise. Just when I go from a stop into 1st or reverse get locked out unless I hold the pedal down for several seconds or go into 5th first or something...

Stack up height may be short. We have to use a spacer on Exedy clutches to get correct throw to fully release. May be the same in your case. The TOB has a 7/16"-1/2" throw. Measure block face to clutch fingers, then Bellhousing face to un compressed TOB bearing. The difference will be the compressed installed height. If it is more than 1/2" then the bearing cannot release the clutch fully and will most likely over extend and blow out. Ask me how I know. Also if it is just a bleed condition (which is possible if the TOB was not bench bled prior to install, then you need to put vacuum on it and let it hold for a few hours. -16" of Vacuum max. Then pump once, release the vacuum, pump again 10-20 times and put vacuum on again for a minute. Should get the air out.
