Default 04, 5 speed, centerforce clutch. Wont shift!

I had a centerforce clutch installed recently on my 04. Ever since ive had shifting difficulty. At idle it wont go in to gear for nothing. And when it does its kinda rough. I have to pretty much put it in gear and start the truck. It pulls itself a little with the clutch disengaged too. Somehow the clutch doesnt seem to be disengaging completely. Ive bled and bled and bled the system. The slave is new. Nothing leaks. I dont know what else to do. Its pretty annoying. If i take it out of gear at a stop light, i cant get it back in. Or when trying to back into something i cant get it in reverse. Truck has 150k miles. any ideas?

you need a shim as the centerforce clutch setup is thinner then stock

reason for **** poor engagement or none at all is the clutch isnt fully disengaging

Ok. I did some research on it. I need to ask the guy who installed it if he shimmed it or anything. Also im wondering if my master cylinder may be taking a crap on me. Because its seems to slowly be getting worse.

Ok im still having issues. Took the trans out yesterday. Issue is the trans is a full one piece design. when normally you measure for shims from the bellhousing to the pressure plate fingers and bellhousing to throwout bearing. subtract em and you need .12 to .2 difference or so. But i had to measure from the block so the only i could actually come up with was the total clearance between the pressure plate fingers and the throwout bearing. I come up with about .48 inches, give or take a hundredth. I really didnt know where to go from there so i put in the middle shim out of the tickperformance shim pack, .113 i believe. got it all back together,, still has the same issue. What i dont understand is why is was working fine for a couple weeks after install, then got worse. I had the flywheel resurfaced, replaced the slave. something just inst disengaging. When at a stand still neutral position, i try to shift into gear, it and makes the truck start moving forward , but wont go into gear. And while in gear with the pedal on the floor, it trys to pull forward. any ideas here?

the reason it may have worked was when the bolts were first tightened they were close to spec. if they may have backed out some, now the slave cylinder has to make up for that and simply does not have the travel to make up for it. it could also be air in the line i fought my nv3500 like crazy with air in the line. but it sounds like like some loosened clutch bolts to me. mine did the same thing

Ive bled it and bled it and bled it. And with no leaks, considering it was working fine at first, i dont know how air could have gotten in. I'm assuming you are referring to the pressure plate bolts where its bolted to the flywheel correct?
