5 Speed Transmission help

I have a 1995 Trooper with a 5 spd manual trans. It will only drive in 4th gear.
I was on the high way in 5th gear when it just popped in to neutral so I pulled oner and tried all other gears and only 4th would drive it.
Any suggestions would be greatly appeciated.

my trooper 5 speed lost all but 4th gear and I have had to rebuild it. It was very simple and I can give you some pointers if you need. [email protected]
