ok im used to working on foxbody cars with normal trannys in them. my truck (f350 powerstroke) is giving me problems. the clutch wont disengage all the way. i checked the fluid level in the master and its full. i think its the slave cylinder going bad and pressing the clutch fork all the way. but one guy says it might be my clutch and another says the dual mass flywheels go out before the clutchs do? god i hope not i think those flywheels are like an arm and a leg arent they?
