Strange Clutch Feeling

Well, an issue that happened during the winter sometimes has come back with the recent 40's and 50's at night it seems. Driving the car around, when the clutch is being slipped taking off in first or going into any gear, and using the clutch, it feels incredibly stair-steppy, vague, and I almost feel a vibration or buzzing during that moment of power-transfer when slipping into gear? Hopefully that makes sense............ My car has been acting like this since I raced it Friday night. It still bangs gears meaning it's not slipping.

Could this be a slave cylinder issue? Hydraulic issue of some sort? Some sort of clutch/clutch line issue?

The clutch acts very VERY vague during this. I'ts like it can't just act normally, like it just isn't a smooth transfer of energy between engine to drivetrain in the act of changing gears.... (wow, really hope this makes sense)!

Makes sense to me. My diagnosis, maybe(and i hope in wrong..) the pressure plate forks are damaged.
If so this can explain why it feels like it kinda wants to put up a resistance when to press on the pedal and it feels kinda jumpy and scrapey.
Obviously if the pressure plate forks are bad clutch function will be adversely affected.

At worst it will be that. and since you were racing and i imagine you were putting the clutch to good use it is possible the forks on the plate might have bent due to the sudden release impact.
Take a look under there and see if they seem out of shape.

other possibilities might be a bad clutch cable as you said, maybe the throwout bearing, maybe even the forks on the clutch fork which may have bent just as i speculate the may have happened to the pressure plate.

I experienced the same symptoms as you for about 3 weeks and today (snivel,snivel) my clutch died.
I knew the pressure plate was bad... saw it with my own eyes. It was just a matter of time.

Good luck with yours man.

Can be from getting brake fluid hot in slave cyl. Try pumping clutch pedal see if fresh fluid can work it's way down there. If you want can take line off at trans then pump pedal to get air out. Give it couple days see what happens see if it works out of it. Remember brakes can do the samething too after day of track.

Hyd clutch can act weird at times I'm still dislike mine in 11GT. My car I should atleast put new fluid in the car then do clutch line upgrade. I like cable clutch like 99, both 04 mach1 and 76 cobraII. Feel like I have more control over the clutch release and engagement

When I replaced my clutch line it made a huge improvement in clutch pedal feel. Every time I drive a stock GT the difference is very noticeable so if you ever want to drive mine let me know.

Ok well not sure if its the pressure plate. It did this when the car had less than a thousand miles on it intermittently. The cluth action at the FRICTION POINT feels spongy, like the pedal has a slight vibration at that "catching/friction" point.

I found a thread at svtperformance that talks about the Joe Heck line which is in Grimace'a signature. NOAA National Weather Service. The one guy Torch10th talks about his feeling spongy and I think he has the same issue as me. It does feel like the possible culprit could be some air in the line, so I will try the 10 slow pumps before starting the car until it feels better I guess. My car needs to be looked at for a groaning shock or control arm bushing passenger side front, so ill probably buy this thing and have them install this while they are working on it to warranty the work they did.

Joe Heck Racing Clutch line - SVTPerformance. Oops. That is the link. Lol. I copied and pasted that link to a friend earlier. Pikes peak is about to have two feet of snow fall over the next few days. Crazy. That is what the original link has.
