You need a new clutch
Is it an automatic? Time for a new transmission... If a stick and 1st, 3rd, 5th are ok, then you have a possible shift cable problem. You should be able to see them on top of the trans. If everthing is moving properly the trans has an internal problem.
try flushing the transmission and putting a new trans filter in as well
You either need a new transmission or a new clutch.
It's a Jeep thing, all of them do it!!
Well you have a strange issue. Being the trans will not shift into any but reverse would point to the clutch being toast. Normally if the truck will not shift is the slave clyinder or even the clutch master or throw out bearing gone. To rule out the the throw out did it noise while the truck was in neutral and even while in gear.If either apply may be the throw out is gone, but sounds 100% clutch is gone. If the truck will shift into soley reverse then this would rule out the slave, and clutch master cyldr and even the throw out in most cases due to the it is moving the fork to engage the clutch and the surface of the clutch is worn to it's life except reverse due to it is not used as much. I recommend a new clutch and replace the throw out bearing and would be a good idea to replace the pilot bearing and go ahead and do the rear main seal even if its not leaking if its got lots of miles, plus the age would make me do it being you have the trans pulled out.
Your pressure plate and throw out bearing in your clutch assembly are worn out...time for a new clutch
time to get a new car!
