clutch on gtv6

[franck]

G'day guys, the clutch on my gtv6 i think is trying to tell me something that im not sure i understand, so some assistance from you would help no doubt, car has 120k, and is not the original twin plate, car only driven by me and usually always gear changes at 4-4500 revs, however the last drive decided to play a little and took it to 6000 in second and third gear, not droping the clutch between changes but once in gear in  progressivley flat to the floor acceleration, no slipping but the strongest smell of clutch/rubber in the cabin ive ever experienced, and then from standstill normal takeoff shuddering, any ideas? clutch does not slip i can use all the torque available up a hill and no slipage, but at high revs it stinks.... i dont think its me either!
