Actually... you're not going to believe this.
The Slave was BONE DRY. I filled it up with Napa dot 3 (only stuff I had laying around in the shop), pumped the pedal about 50 times with the engine running, and now it only feels like a worn clutch.
As opposed to, an "OH SHIT I CAN'T START FROM A RED" feel that I had just earlier this day, where I literally had to SHOVE it into gear from a stop. (For the shifting itself, I very carefully clutchless-shifted.
