Jeep only shifts when off

After driving for 20 min or so it gets harder and harder to go into gear. If I'm parked somewhere and have to do a 3 point turn I have to turn off the jeep when I stop to be able to get into first or reverse. What the hell is going on???

Clutch is not releasing all the way. When the tranny is cold there is more drag to slow down the countershaft. When it gets warm that doesn't happen, so it is harder to shift.

Maybe your clutch master is low on fluid. That's the easy fix and if it is not that you will have to do a deeper dive.

I do concur with plym, I believe what you are describing is caused by a failing hydraulic system. Look for leaks from your clutch master or slave either inside the firewall under the dash where the rod comes thru from the clutch master, or dripping from the bellhousing from the internal clutch slave. And of course, check the fluid level in your clutch master cyl reservoir. I'm going to guess it will be low.

If you are able to range thru your gears fine with the engine off, and it doesn't want to shift at all when running, your problem isn't inside your tranny but likely hydraulic related.

Yep ... what they said.^^^^ I experienced the same thing. New clutch master & slave cylinder and I was good to go!! Make sure you bleed it well or it will still act up. Air in the system compresses .. brake fluid doesn't. Good luck !
