Can't go in first while at a stop
 

So went to the track yesterday and after a couple of runs I realized I couldn't go in first after the car came to a stop engine running. Decided I better check my clutch fluid and flush it before I assume clutch is gone. Pulled some fluid out with a syringe and found a bunch of black build up in reservoir. Is this normal or something pretty wrong? Car and and clutch maybe has 5k miles on it after swap.

Not normal. You need to bleed the whole system until it comes out clean. Hopefully you have a remote bleeder already. If not, now would be the time to install one so the tranny doesn't have to be pulled next time you bleed.

Why would you have to pull the tranny to bleed it? It is a t56 Can you not just bleed using the valve coming off the slave cylinder. I have a hole drilled in my tunnel just for this haha did that by pushing the petal in and went through like half of a bottle of dot 4 just flushing it through. Not sure if I got air in the line but still doesn't seem to want to go into first while not moving :/

*definetely have air in line brb while I use JDM method of bleeding

Oh, well if you've got the hole then you don't need to pull. I wasn't going to recommend cutting the hole though haha. May have to pull it anyway and check everything.
