I have a clutchmasters fx400 and the car was fine until one day a while ago the clutch started slipping. Mainly while going up hills and on the highway. Starting tearing it apart a few years ago to put a new clutch in, got in a bike wreck and quit working on it for a while. I finally got it all put back together with the intention to sell it for whatever I could get for it. But the other day I decided to take it for a drive and it has me puzzled. You can put it any gear, then let the clutch out, and nothing happens. It’s doesn’t stall, lurch forward, nothing. To back it out of my garage I have to rev it to probably around 4K rpms before it starts to move. I can drive it but to start out in first or second gear, it’s the same way. I have to rev it to the moon. After I start driving, it seems fine. I punched it in 3rd (car makes roughly 400whp on the low boost tune I was on) and it hooks up and throws me back in the seat. Plenty of feeling in the clutch pedal, no visible fluid leaks. Any idea of what this could be before I start tearing it apart again? Its a 2013 with 23,500 miles on it.

Do you still have the factory clutch line installed?

Your story isn't exactly clear. Did you replace the fx400 with a new clutch?

Start with the easy things, fresh line and fresh fluid. Brake fluid will absorb water over time. Could be something like the master/slave on their way out too. Of those, master is easier and quicker to do.

When the fx400 went in, what mileage was that and still on stock slave?

Edit, just saw the car only has 23k miles, likely not the slave...unless it's due to age/seals or something from sitting 🤷🏻‍♂️

Yeah put an upgraded clutch line in there (make sure you don't reuse the factory restrictor) and bleed. I had similar issues (clutch staying disengaged) and my clutch restrictor was the culprit. Braided line took care of it.

I think it had around 20k miles before it was built by speedperformance. It’s probably the stock slave.

Thanks for the quick replies. I just ordered a stainless line. Fingers are crossed

Any tricks to getting the clutch line plugged into the master? I’m pushing in it with two pry bars as hard as I can and I cannot get this thing to clip in.
I'm 99% sure the little black seal from the original hard line is stuck in there. Get a bright light and a little pick to see and pull that out.

It's designed so that you can put the clip back into the master first, then push the clutch line in. It will snap in place with a "click".

**** i had it still in with the stock line removed but I took it all the way out thinking it may have been what was holding the CM line. 🤣 I appreciate all the help. Hopefully It’ll be on the road in an hour. Yeah right lol
