this problem just started to show up a little while ago. When ever I'm getting on the car and i go to shift the clutch will only return halfway. it will pop back up after a while or if i pump the clutch it will return all the way. Sometimes,when it does this, I can't even get it out of gear . I have been asking around and some of my friends believe it is the slave cylinder (by the way its a '00 Z28, i know they upgraded the slave cylinder for '01, i have the original with 50K mi on it). Could you guys help me out? Also is it wise to replace this without replaceing the clutch? Thanks guys!!
