Default Strange transmission problems

I have an ap1 with some transmission problems:

1. When the car is off the clutch pedal goes in like normal and the car shifts into gear but it feels really notchy but when the car is started the clutch pedal feels like a brake pedal does when abs is activating, the pedal is really pulsy while being engaged.
2. The car wont will not go into any gear while the motor is on plus when I try to put it in gear the car starts to roll as if the clutch inst even engaged. I had to turn the car off place it in 4th gear then start it and give it gas to even move the car. Once the car starts the transmission will shift normally but only for a short time then same problems all over again.
3. Also sometimes when the clutch pedal is pressed in neutral it makes a faint scraping sound. I was going to get a sound clip but of course it is quiet now.
4. When I was able to drive the car it would shift going 1 -6 but if I try to go from 6th gear to 5th gear it doesnt want to go into gear. It pretty much does that when ever I try to down shift.
5. If im driving down the road and put the car in neutral and just coast and then try to put it back into gear it is really difficult and doesnt want to go in until I do a rev match.

The transmission hasnt been feeling the best for the past couple months and in that time I have checked my fluids plus regreased the shifter and slave cylinder rod. I'm only making 470 on pump gas and 590 on race fuel but I dont abuse the tranny at all, I run a lower boost in 1st and 2nd gear, I never really take 1st or 2nd gear above 6000 rpms, and I only get into full boost once I'm in 3rd gear and higher. Sorry for the long post but I wanted to be prepared for what the problem could be once the transmission is pulled later this week. Thankfully I have a spare tranny but I wanted to know if anyone else has had this experience.

Your clutch is broken, most likely a spring has popped out of the clutch disc and is all jammed up.

What kind of clutch do you have?

Yep, I'm willing to bet a spring or 2 popped out. Time to pull the trans!
