How else can you explain regaining a normal feeling clutch after turning the car off for 10 seconds? Then it deteriorating to the point of 'un-shiftable' after another 60 seconds of driving?

The 300zx has the same clutch layout with the line right next to the cat, same with the 350z DE (external slave but clutch line in the same spot)... I don't hear about their CSC going out in record numbers like on here. In fact, the 350z HR and 370 have basically the same csc and both have extremely high failure rates. Like I said before, I believe its the seal within the csc itself. So if its heat related, why aren't guys boiling their clutch fluid when they have a Zspeed HD csc installed? The clutch line is in the same spot, no difference except the csc isn't made out of cheap plastic and uses better seals. But you seem pretty convinced its your fluid that is boiling during normal street driving so have at it. At least you have an extended warranty so when it goes out again Nissan will have to replace it. I had the HD csc installed over 2 years ago and haven't had an issue... Come to think of it, out of the hundreds that have installed the HD csc, I think I've heard of 2 failures.
