Hey guys, I'm having issues bleeding my clutch on my M32 6 speed. Replaced the clutch with the GM performance unit along with new Delco slave and master cylinder, I cannot get the air out of this thing, it also pumps up like its a brake pedal, I've never encounter this before. Can anyone chime in with any tips or tricks. I was just doing the bleeding sequence per the books description, depress pedal, open bleed valve, then close bleed valve, release pedal, and repeat. Did this many times and it still feels horrible. Really don't want to take it to a shop just to bleed it.

You don't need to bench bleed, I've never done it on a manual car. You do need to bleed the master, then the line to the slave, lastly the slave bleeder itself. If not, all your air isn't getting out of the system. If at that point you have an issue, might be time for a master and/or a new slave. & if you redo, bench bleeding seems like a good idea.
Keep bleeding, keep bleeding, keep bleeding. I've gone through a lot of fluid installing new transmissions before.
When you're all done bleeding the same way you said before, push the clutch to the floor and once slave bleeder is closed on your end, have your helper slide off the pedal to pop it up quickly, don't come off slow. That sometimes helps get the pedal feel back, but the entire system has got to be bled 1st.
.... try popping the clutch when you're all done to get that feel back. Sometimes it's just going to feel sloppy for a while and it settles in long as its all bled.

This is huge. Had no idea this would work as well as it does. (Had an issue bleeding the brakes on my other car.... and it was a shared reservoir between the brakes/clutch, then "helper" decided to mess with the clutch pedal. Womp.)
That being said - I'm still not at all used to the mushy feeling of the Sonic clutch. My WRX and my Camaro have so much more "feel" to the engagement than the Sonic does. Is there a reason for this?

Ours is really soft compared to other cars. I drove a buddy's 2.0t? Hyundai Genesis and the thing was on the opposite end, it was like a race car pedal feel but the car didn't need it at all, wasn't fun to drive.
I'll add OP that you gotta pump the clutch pedal to build pressure before letting air out, if it sticks while pumping gotta pull the pedal up a little and pump some more, not exactly the same as brakes. Hopefully it goes well.

Thank you all for the reply’s, will definitely try popping the pedal up after shutting the bleed valve. I also found some more information from a local clutch guru that was very informative, just in case any of you run into my situation. So if you follow the line from the slave to the master cylinder in the firewall, you will find this weird plastic ball in line between the two. Apparently GM added this to soften the pedal return so it’s easier to let out , like an orifice tube with a check ball in it. He told me this little section is a son of a bitch to get air out of and you just have to drive it for about a week and the air will eventually works it’s way out to where you can re bleed the system correctly. So I’m going to cross my fingers and try to bleed in a few days and hope this garbage pedal feel goes away.
