Does the clutch engage early? If yes, I'd agree with the earlier post that recommended bleeding the system properly -- But before that, remove the slave cylinder from the bell housing (lines still connected), peel back the rubber dust boot and check for leaking fluid in the boot. BTW, the clutch uses the brake fluid reservoir and there's a baffle inside to keep a clutch leak from draining all the fluid.

I had two new slaves in a row that were leakers, and it was more difficult than brakes to bleed. If I remember right, I ended up bleeding it before installing in the bell housing so the cylinder could be angled-up with the bleeder (towards the rear) high to better get the bubbles out.

If you're not into repairs like this, definitely take it somewhere else. If it is improper bleeding and not disengaging properly, the transmission synchros will wear out quickly. And regarding not being able to shift into gear at a stop with the engine running: The only difference is the engine is spinning the clutch. And IF the clutch is truly disengaged, shutting off the engine will make no difference even with a bad transmission.

 

This may help, my clutch slave bleed method is about halfway down this post: https://www.jk-forum.com/forums/stoc...linder-278107/
