i am having trouble with my 2002 2500 cummins 6 speed.. when i depress the clutch it bleeds by and no sign of fluid leak outside of either, could the clutch be worn to a point that the master wont push any more fluid ??? i can also hear it bleed by whether i am in the cab or standing outside under hood.. any suggestions as i am stuck literally cant get it in gear without starting it in gear and then using engine rpm to shift...

 

Sounds like the hydraulics to me which would indicate that the slave cylinder is not able to push out the fork or throw out bearing.
