Today is a happy day! I got the transmission back up and got the car started!! I had some trouble with the CSC adapter plate and got in touch with Seb/Johnathan (I think that's his name) and Rob.

I was struggling installing the Transmission last night. I would slide the transmission in but will was not able to get the transmission bell to touch the back of the block. I would end up with a 1/2' gap between the two surfaces. I would then drop the transmission back down and try it again. The transmission would go in but not slide easy. I got frustrated after 4 or 5 tried and said screw it! I'm going to redo the clutch plate and clutch all over! I removed the clutch and clutch plate then put her back together again. The only difference is that I pushed a little up on the centering tool before I snugged the bolts up. I then tried to pull the centering tool and OMG!! The tool slide out like BUTTER!!! I then try and put the transmission back in place again. This time, the shaft slide in perfectly in, nice and smooth but I still had a darn gap! I finally got smart and peeked in the side opening hole where the clutch lines come out at. The FREEKING BEARING SURFACE was already touching the fingers of the clutch plate!! No wonder why I wasn't able to get the bell to touch the back of the engine! This is when I called SpecialtyZ and they got me in touch with Rob. Rob told me to switch back to the original thinner plate that attaches to the CSC. I said ok. He explains to me that I need to test the CSC with the thinner disc to make sure everything is in tolerance once the transmission is up. I switch out the plate and BAM!! she slide right in easy! I put 3 bolts in just to hold her in place and leave the transmission jack there to help support her. I proceed with the test.

This is the run down:
1-pull out piston part of csc and make mark with sharpy about 1/4'' or 1/8'' from back of piston.
2- Someone stay in car and step on clutch when told
3-someone stay under car and keep eye on the piston (the whole unit is a csc, we are concerned about the piston that moves in and out as you depress the clutch pedal)
4-guy under watch the piston as guy in car slowly steps on clutch
5-make note of grease line as that is maximum depth the piston can be pressed into the housing, also make sure that you don't see the mark you made at the back of the piston. If you see the park, tell the guy inside to stop stepping on the pedal and make note of the stroke position. You do not want to push pass that point and pop the seal and let clutch fluid flow everywhere!
6-tell guy to let go of clutch, and make note of the distance between the grease line and where the piston sit in the housing.
7-theorhetically, you only want the clutch pedal to move the piston in and out 400 mills (a little less than 1/2'')

This is to make sure you don't 1, have too long of a stroke and push the piston out of the housing. 2, there need to be a tolerances to allow the piston to reseed back into the housing (about 1/4'', I marked this with a blue sharpy in the video). This is because as the clutch plate wears down and becomes thinner, the finger of the clutch will slowly extend outward (towards the back of car). If there was no "give" room of this 1/4'', the worn clutch plate fingers will not be able to extend back. This cause a symptom similar to riding the clutch ALL THE TIME! The clutch and clutch plate will burn up a lot faster and cause extra wear and tear on the drive train.

Here is a video of the test.

SHE LIVES!!!! She has a rough idle, I have a check engine light, it says VDC is off (I tried pressing the button a few times to see if it will go away but nope. On a side note, I my "S mode" button is not connected).

I will put most of her back together tomorrow in the daylight. make sure there are no leaks or loose pipes.

After than, I will have someone drive her up and down the driveway and over a 2x4 too see the clearance I have. After all is done, I will put the front bumper back on, give JWick a holla and see about installing the boost controller and Wideband.
