your slave cylinder is leaking,need to replace.
Not 100% sure on an excel, but where is it leaking? If your car has no clutch fluid then you will not be able to change gears, I would check the seals on the master/slave cylinder, as that is one of the more common places clutches leak.
Either the clutch master cylinder or the clutch slave cylinder or the clutch hydraulic lines are leaking.
take it to the shop to get fixed!
The clutch uses DOT 3 or 4 brake fluid, and shares the reservoir with the brake system. The brake fluid reservoir is the same as the clutch fluid reservoir.
you need to bleed your clutch fluid
DOT 3 brake fluid.
dot 3 brake fluid the blue one
It wont shift because its leaking fluid.
The clutch master cylindar is most likely leaking. It's literally a hydraulic piston attached to the clutch pedal. It is also possible that brake fluid is leaking from the brake master cylendar and running down the line to the clutch pedal, ending up inside.
You can't have it both ways. If it's using fluid, then it is leaking out. If you are not seeing any on the ground or at the slave cylinder have you considered that it may be leaking from the back of the master cylinder and running inside of the car. You may not have noticed because it is going between the firewall and the carpet.
Clutch brake fluid hole doesn't make sense. Where do you fill the clutch? It's leaking and where's the leak? Try rephrasing your question.
Dot 3 or Dot 4
