Clutch bleeding HELP!!!!

I’ve got a 1999 4Runner 3.4l 5 speed, I was driving and went to shift and noticed my clutch pedal felt soft and didn’t come back up, I’ve had this problem on a different vehicle so I checked the slave cylinder for leaks and had none, but I had lost the forward most bolt for the slave cylinder but still had one, I tightened the one and got home and got a new bolt in, after that I found that if I left the clutch pressed in it would loose pressure and not come up unless I pulled it up, then I could shift if I pressed it and let go fast, if I held it for any amount of time it lost pressure, I replaced both the master and slave cylinder and have bleed the hell out of them and I still don’t have the same clutch pressure as before and can’t get it into gear, from what I can tell the slave is extending all the way and my adjustment at the pedal is fully adjusted out, I’m lost and need help.

 

Are you loosing fluid??

 

No, no leaks anywhere and when I bleed It I’m getting plenty of fluid through and making sure the resivoir stays full

 

Also today I tried pushing the slave cylinder inward and opening the bleeding, closing and releasing it, that’s when it started extending all the way and I have better pressure but still won’t engage
