Transmission problem
2002 Other Peugeot Models 6 cyl Front Wheel Drive Manual 45000 miles

hi guys, i have a peugeot boxer van and the prob is with the clutch. the other day it felt like a dink noise underneath the pedals then travelling further up the road i noticed the the van was a bit sluggish on changing gears( as if i was riding the clutch) even though foot not on pedal. was told it could be hydraulic clutch which makes sense as the clutch feels very soft now(as if no pressure there) took it to my mechanic who could see no visible problem, he lubed all parts but the problem still persists. any ideas????? im a delivery guy and wondered if it would cause further damage or even put myself at risk. cheers
