had the same exact problem with a 94 that had an xtd stage 3. clutch felt like it wasn't grabbing until one day about 2 weeks after it started it went completely. cmc and csc were both fine, but the day it went out i was driving, parked at a friends house, went back to it 3-4 hours later and all the fluid was gone in the cmc, yet it had no visible leaks. i think it had something to do with the weather...
