Default Slave cylinder replaced, bled, no luck

i replaced my clutch slave cylinder due to it being obviously faulty and leaving me stranded, i put the new one in, (mopar) and proceeded to bleed the system, couldn't get any fluid out, so i replaced the line from the master to the slave, HELLO fluid from the bleeder, bled all the way out till visibly no bubbles, got in my jeep and the pedal may be a little stiffer but still won't go into gear, i am at my wits end and can't have it to a dealer till next week, i am emotionally exhausted from this any input greatly appreciated.

My only thought is that maybe you didn't get all the air out. I'd try again on the bleeding. Sometimes its a pain to get a clutch system bled properly.

How many miles are on the transmission? The slave is pretty straight forward and bleeds easily. You say the pedal is stiffer so we can assume that the plunger is contacting the fork that swings your throwout bearing.

The whole system is pretty simple and quite straight forward.

It has 65k miles. And I bled it out with a vacuum bleeder for literally 4-5 hours, when I stopped there was not a bubble one in that fluid. I'm starting to think the throw out may be siezing. Having her towed to the dealer this morning when they open. This is my daily driver and I can't afford to guess at it anymore, at this point I'm just going to tell them to give the bill and get my blue Elvis back on the road. I will update when I get it back from dealer

How long did you bleed the slave cylinder?

When I replaced my clutch my slave cylinder boot was punctured and needed to be replaced. I had to spend about 2 hours bleeding my slave cylinder to get enough fluid in the slave cylinder to operate properly. I would suggest continue bleeding for about an hour or more then put the Jeep in gear have someone sit in the Jeep depressing the clutch and give it a little push. that is what I did to ensure the slave cylinder is operating properly.

Once you have the slave cylinder bled it will seem a little light but over a couple of days you will feel the clutch getting stronger.

Just a regular bleed works, no need for the vacuum. Another thing worth noting is that you want to go slow with the pump and release on the slave when you're bleeding. It doesn't respond well to the rapid pumps.

Your fluid reservoir was absolutely brimming, right? It seems that the master/ slave don't pick up fluid until you're at the top of the reservoir with fluid. Those have just been 'best practices' in my experience.

You weren't wheeling in deep mud or water when it went bad were you? Its pretty easy to get mud and rocks in the pressure plate clutch fingers which can disable the clutch.

Buried my JKU to the bottom of the doors in a mud hole and I had nasty mud and grit on the flywheel and clutch assembly. Finally could not take the noise anymore and removed and replaced my clutch in the garage. took my time and was able to complete it in about 2 days. I had never done something like this before so I took my time. Next time I will be able to complete it in a day.

Yeah same here, ruined two clutches in the mud. Doing the clutch was a PIA. Both times I tried to do it with the transfer case attached, bad idea on a cheap transmission jack.
