Damn clutch, I'm out of ideas...

When you had the transmission replaced, you needed to replace the CSC again. The CSC seal was damaged during the transmission replacement. Depending on which clutch/pressure plate you used would determine which CSC is best for your application.

My prefered choice of CSC is from ZSpeedPerformance. Pricey but bulletproof.

Sorry for the bad news, but there is no way around this one. You can try replaceing the clutch master cylinder but I believe the CSC is damaged.

If this problem started happening after the tranny replacement I would agree with you. But the problem existed with the first tranny, clutch, pressure plate and CSC. The problem existed with the first tranny, aftermarket clutch, aftermarket pressure plate and aftermarket CSC. The problem still exists with the second tranny, new stock clutch, new stock pressure plate and aftermarket CSC.

I would hate to replace my new Zspeed CSC but I would gladly do it if I knew it would resolve the issue. Unfortunately I don't think it will. Otherwise wouldn't the issue have been resolved when I had the aftermarket CSC installed on the first tranny?

Mr&Mrs,
I see that you're in Tampa. If you have time one weekend I'd like to meet up and have you take a spin in my Z and get your opinion on the clutch/trans.

Same symptoms but different issues. I still stand by my diagnosis.

If the OP wants to be sure that it's not the CSC, it has to be a FULL system check, including the transmission shift alignment plate, master cylinder, measure pedal stroke (is the master cylinder even tightened properly to the firewall?) clutch pedal limit switches and pedal stroke, is everything straight and lined up? You can go further and check the orifice block in the clutch line, measure the volume of fluid the master cylinder per pedal stroke and bleed the CSC again and again. ..... and bleed it again!

One tip that Joe gave me was to pump the pedal several times before releasing the pressure to move the air bubbles to the top of the bleed line. Then do it again and again and again.

Then after all that you have to ask is it the pressure plate that’s broken?
Is the clutch frayed and catching? What if the pressure plate isn't tightened up enough and therefore not releasing the clutch fully?

I really have a hard time doing internet diagnosis as one never gets the full battery of symptoms or all the issues. I prefer to use all my senses in diagnostic analysis (touch, sound, sight) to determine the problem and try and find the issue.

My recommendation is now to find a excellent clutch shop that knows our clutch systems (it is very common now to find the CSC's on most vehicles now) and do a proper diagnostic check to determine the cause.
