Hello I have an 02 Boxster with 86,000 miles. I recently drove the car to a friends house and everything was fine, when I went to leave the clutch started slipping and finally went altogether. There were no signs of a problem previous to this. No slipping, no grinding, and no smell of a burning clutch. The pedal has pressure and you can hear it going into gear when you shift it. However it just acts like it's in neutral. Any ideas? THANKS!!!
