i have a 97 sh 5 speed with about 130k miles on it. i recently started feeling a bad sensations from my clutch on my foot as i press it down to shift. it feels rough or ginding like during the motion of being pushed down. it only happens when i'm shifting gears and when i'm going my about 15 mph. when i'm in neutral and shift, it's smooth like it's supposed to be. the clutch fluid seems to be where it's supposed to be. anyonne have any ideas? does this sound like i need a new clutch? thanks
