I can shift into first and reverse, but I have to turn the truck off to shift out of gear. I'eve replaced the master cylinder, slave cylinder, and the hose. I was wondering what could be causing this. When the truck is running I cannot in any way shift out of gear. The only way I have found it to either kill it, or turn it off. Anyone know what this could be, and how to go about fixing it?

Does the clutch disengage when you push it in? When was the last time it was replaced? It's also possible that the input shaft inside the trans is worn and causing the gear to jam on the shaft.

Make sure all your hydraulics work and not binding. Then have your clutch checked. If you can shift it with engine off then it's probably the clutch
