Weak clutch pedal pressure

Hey guys I have 97 TJ 4.0 with an AX15. My TJ has been giving me problem shifting into gear. First I changed the clutch with a completely new kit. But that still didn’t fix the problem. Then I changed the master cylinder, but still the symptoms remain. Just today I changed the slave cylinder and still it persists. So here are the symptoms: The clutch pedal will go to the floor. I can pump it and get some pressure to it and actually shift but after about an hour the pressure is completely gone again. There are absolutely no leaks and the fluid level does not go down!! What is the problem? I have replaced everything you can replace when it comes to the clutch except for the fluid line because there are no leaks. Does anyone have any ideas? And yes the cap is on tight, I torqued the pressure place to specs and the TJ will shift beautifully when I can keep pressure in the pedal.

If you bled the system I can't see where there would be a problem. I would bleed it again just to be sure. It sure sounds like air in the system. Not sure if you need to bleed the master cylinder first or not.

I have a 2007 Jeep Liberty Sport, I have the same problem with the clutch pedal. I changed all of the same components. When I bought the master cylinder and the slave cylinder, I was told that they were a closed unit and were factory bled. I even looked for a tool to bleed them again (which I could not find). But I am curious what the solution is to this problem too.

:confused: When I replaced the clutch on my 98' 4.0,the slave and master cylinder was a sealed unit that requirded no bleeding.After install, simpy pushing in the clutch opened the sealed unit and fluid.You don't need to and shouldn't have to bleed it.
