so me and my friend were on the freeway..i was shifting from 3rd to forth at probably 5000rpm and ounce i stepped on the clutch to go to 4th the clutch pedal stayed down..so we pulled over..and i grabbed the pedal with my hand and pulled it back up..i pumped the clutch pedal a few times and it regained pressure..but too much pressure??? i have to step pretty hard just to start the car..also when i got the car to start..i could not get it into gear..even if i stepped on the clutch pedal hard..it feels tooo stiff..my friend says its the slave cylinder..any suggestions on how to fix this??
