I have a 5-speed manual 2001 Accord and the clutch pedal is very soft. When you pump the clutch it does get harder and when the engine is warm the car does go into gear. When the engine is cold the pedal is extremely soft and the car won't go into gear at all. I am thinking clutch master cylinder is the culprit? If you know of anything else that is likely please let me know. If it is the clutch master cylinder how hard is that to replace?
