Need some help/suggestions; YJ won't go in gear after new clutch/transmission swap

Need some help/suggestions; YJ won't go in gear
Background: 95 YJ with 2.5L Manual AX5 Transmission, 231 Transfer Case

Swapped in a 98 AX5 Transmission and a brand new clutch. Torqued everything to factory specs, maybe a little over for good measure. Filled with fluids:
Np 231 ATF 4 Auto Trans fluid 1.75 qts or so
AX5 10W30 Mobile oil, approx 3.5 qts, but a little did leak out on a level surface.

Buttoned it all back up, ran amazing for the test run, all gears shifted, smooth, able to downshift for a change. Ok, great, time to cleanup and head out. Got in again and noticed the smooth shifting was becoming rough. Took for a quick spin, brought it back and parked it. Came back and now I can't even get it into gear.

Here is what I have done so far:
pumped the crap out of the pedal; no change
swapped 98 slave cylinder in, no change
pumped clutch again, and even flushed the lines with new dot 3 fluid
tried pushing on the fork by hand, couldn't budge it ( good right)
checked transmission fluid, right at the top

The Jeep will not go into gear now when running. Off you can get into gear, kinda rough sounding.

Any suggestions? My buddy believes that somehow I have air in my lines, but the master and slave cylinder are unbleedable like traditional setups. There is pressure on the pedal with some play. I really don't want to pull the transmission again.

Thanks for any help and suggestions,

There should be a bleeder screw on the slave. There's a little nub on top of the slave towards the back, the screw it's recessed in that nub and takes an allen wrench. There's no nipple like a normal bleeder screw, so it gets messy.

Yeah you need to bleed your clutch. Internal slave cylinder bleeder is a little nub popping out near the bell housing. This is what it looks like with the pegot trans.
