Default so what's going wrong here now?

Well, I had the transmission rebuilt before, and the car started grinding into 2nd a few weeks later, so I took it back to the guy and he said a C-Clip broke and went in between the gears and jammed everything up, so he took it back and fixed it and it was working fine for a few weeks.

Well, a few weeks into it, the car started occasionally banging into/falling out of reverse, and I called the dude and he told me to bring it down when I felt like it and he'd take a look at it. It didn't really bother me too much, so I never really did anything about it.

On tuesday, I was driving the car to work, I was slowing down to about 15-20 to go through the EZ Pass booth, and went to downshift into 2nd, and it started to grind. Son of a bitch. Gears 1, 3, 4, 5, 6 were all fine, but then it became almost impossible to get the car into any gear. I took the car down to his house, he thinks the synchros are fine, and that my clutch is dragging (which I suspect may be the case, sometimes I couldn't get it in gear until I'd pick up off the clutch a hair while trying to get it in).

I parked the car (obviously) in the garage and took the transmission out, and here I am with a clutch sitting in my garage.



Cliffnotes:

Fresh trans rebuild grinding intermittently into 2nd, very difficult to get into gear, car has new master, slave, pressure plate, clutch, and flywheel. I do not think the clutch is engaging the whole way. I did try bleeding the system. Car also intermittently has trouble (meaning it's impossible) to get into any gear, 1-6 or R

When I started my car after the initial grinding sound, I heard a rattling sound coming from inside the transmission/bellhousing area that went away when I pressed my clutch.

When I pressed the clutch at idle a few times, you could hear it banging.

When the clutch wasn't entirely engaged, you could hear it spinning (or something spinning) inside the cabin of the car.


What do you think, clutch/pressure plate, slave, or transmission?

Since you have the tranny out, what does the clutch, pressure plate, flywheel look like? I think you need to send the box to one of the T56 specialists sponsors to diagnose what is wrong.

Clutch looks good. Pressure plate has a few bent prongs but nothing too bad.

I should also say that 99 percent of the time, when you're shifting at higher (3000+) rpm's, and you press the clutch in, you hear something buzz and wind down, and you can also feel it in the pedal. Its an 04 cts-v with ls7 clutch gear. Could this thing need shimmed?

Well I checked the car out again, and found out it wasn't water, it was brake fluid. Its leaking into the green sleeve.
