I took my truck out the other day and out of nowhere it was having trouble driving. It was like the clutch was half way in. Out of nowhere! Theres no smell. No previous symptoms. It i only has 50K. I cant imagine it needs a clutch. Anything g that could be causing this? It has the internal slave cylinder. Could that be jammed? I guess the tranny is going to come out regardless to fix the issue. Just trying to understand what happened a little bit

 

Before you bleed check for leaks and cracks, and get all the parts ready.
Don't forget to download the PDFs below, too many pages to attach as jpg individually.

 

Just to clarify, the clutch is disengaging fine, its not Engaging. When i release the clutch pedal, the truck will barely move.

 

You might consider the following,,,,,,,,,,,,,,

Either crack open the bleed fitting on the release bearing OR crack open the line from the clutch master cyl and see if it will engage now..
If it will still not engage, there is a good possibility the clutch disc is completely worn and may require replacement.
Let us know what result you get, thanks.
