ive got an 07 dodge, 6.7 cummins, 2wd. clutch pedal just stopped like something was holding it up. I was towed home, i've replaced master and slave cylinder and put trans back in. Clutch was fine, replaced throw out bearing, put everything back together, clutch and cylinder are working fine, but the clutch fork will not depress by hand or by slave cylinder! i've been working on this for a month, don't know next step.............ive got to get this running, its my work truck!.............
