Thats exactly what mine is doing! I've learned to drive with it again (it still runs fine, just requires a much lighter touch on the clutch)
I would leave it at that BUT I also managed to defeat the clutch today on a full throttle acceleration(2nd gear), when my foot wasnt even on the clutch petal. (pesky V-6 mustangs just ask to be burned) That alone tells me its more serious than I thought.
I will take it in, its a NTCNA vehicle, its just a hassle to get a vehicle from the test track and all. I seem to know the Company Vehicles guy waaaaaaaaaaay to well as well, I dont want to keep calling him with problems
