Slave cylinder bad??
Clutch pedal goes down to floor and leaking fluid from transmission car turns on but not go into gear
My car has 57000 miles.
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
If you have no fluid in the clutch master cylinder and a leak in the clutch area where the clutch slave cylinder is, then it must be leaking and needs to be replaced. Keep in mind that when it is leaked, it may have gotten the clutch disc wet and the clutch would need to be replaced at the same time when the transmission is removed. If you want to have this looked at, a professional technician from YourMechanic can come to your home or office to diagnose your clutch issue and make the appropriate repair.

If the clutch slave cylinder develops any sort of leak internally or externally it may cause the pedal to feel spongy or mushy. The pedal may also sink all the way to the floor and stay there when depressed, and may not be able to properly disengage the clutch so the transmission can be safely shifted.
Clutch Pedal Remains Stuck to the Floor. Clutch Pedal Feels Loose or Spongey. Clutch Pedal is Hard to Engage. Transmission Makes A Grinding, Whirling or Chirping Noise in Neutral.
The most common issue for clutch master and slave cylinders is contamination of the hydraulic fluid or even the wrong type of hydraulic fluid being used. The smallest drop of contaminant, such as engine oil, gearbox oil, washer fluid or antifreeze can cause the rubber seals within the cylinder to swell up overtime.
Even if there is no external leak, slave cylinders can go bad internally.
Sudden failure is most often caused by a broken or loose clutch cable, linkable or a failed hydraulic master/slave cylinder. There can also be leaks in the hydraulic line or even the disc could be contaminated with something like dirt or debris.
Like the disks, it is subject to wear. However, when damage occurs, the CSC cannot be repaired – replacing the slave cylinder is the only option.
If you are experiencing any of these issues, it could mean that your clutch is going out: Squeaking or unusual grumbling noise when pressure is applied. Difficulty changing gears. The clutch pedal feels sticky, is vibrating or appearing to feel spongey or loose.
If it is found under the clutch area of the engine/transmission, it`s the slave cylinder that has worn and failed. Clutch master cylinder failures tend to leak clutch fluid onto the carper above the driver foot pedal area. There will be a bit of an acrid odor in the vehicle if this occurs.

Yes it may cause problems. You could put stress on the transmission input shaft and gears, the engine crankshaft and the drive train of the vehicle. Some of these components could get broken.

What is the name of the clip that holds the slave cylinder line into the slave cylinder 1994 Ford Explorer
ANSWER : Hi there. The clip comes as part of the slave cylinder. The clip is called a quick release line clip. This is a plastic retainer that puts pressure on the line to hold it in place. Typically you cannot purchase this by itself.

transmission wont push back on clutch slave cylinder
ANSWER : Hello,
The slave cylinder is meant to be bench bled just as a master cylinder is. If this is not done it can cause air to remain in the slave cylinder. This will allow the slave cylinder to fully compress and create no pressure. This is the reason that the pedal does not return. I would recommend removing the slave cylinder from the vehicle and attaching it to a bench vise. Once this has been done you can then bench bleed it to remove any air inside of it. Then reinstall it to the vehicle and continue the process from where you left off. YourMechanic can replace your cylinder if necessary, you can find out more information by click here

Car dealer says there is a slight noise in transmission,then says it’s the slave cylinder, does that cause a noise? 2003 Mitsubishi Eclipse
ANSWER : Hello – no, a slave cylinder will not create noise – clutch or transmission – on it’s own. Noise when the clutch is out, and the transmission is in neutral, is generally the transmission input bearing or countershaft bearings. Noise when the clutch is pressed can be the clutch throwout bearing or pilot bearing. I recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

If slave master cylinder is bad, will that cause the car not to hold when parked in gear?
ANSWER : From your explanation of the situation, it sounds to me like your vehicle may need a new clutch. If you are in gear and the vehicle struggles to move and the engine speed increases, the transmission is slipping. A failure in the hydraulic part of the system may make it difficult to drive the vehicle or change gears. Consider hiring an experienced technician like one from YourMechanic who can come by and take a closer look at your slipping clutch and offer a more personal diagnosis.

Replaced clutch master and slave cylinder, but my car still won’t go into gear while running
ANSWER : If the hydraulics are working correctly, there are a couple of things that could be wrong with the clutch that would prevent it from releasing. Unfortunately, any of them will require removal of the transmission for repair.
At 191,000 miles, it could be that your pressure plate has failed and is not fully releasing, or it could be that the disk is severely worn and there is an accumulation of debris between the disk and the plate which would also keep it from releasing. Either of these would be corrected with a clutch replacement.
If you contact YourMechanic, they can send a technician to your home to evaluate your problem and help you figure out what to do next in order to avoid any unnecessary repairs.

Clutch pedal goes to the floor and doesn’t return
ANSWER : Hello, thanks for your question. You could watch the clutch fluid as it mentions in the test, but this really doesn’t tell you much. Most of the time this is caused by a bad clutch master cylinder. If the fluid level is low the first thing to do would be to locate the leak. If the fluid is full then I watch to see that he clutch slave is moving when the clutch is pressed. If it is and if it is releasing but the pedal stays down then that is another reason to change the clutch master. If the clutch slave and fork are not releasing then it may have an internal clutch failure. If you would like help getting this inspected or repaired, consider YourMechanic, as a certified mechanic can come to your home or office to perform the inspection and make or suggest any repairs needed.

I have no clutch it goes to the floor and I cannot find the slave master cylinder for the clutch master cylinder please send pics
ANSWER : The reservoir supplying the fluid to both cylinders is the brake master cylinder reservoir. However, adequate fluid there means nothing as a diagnostic. The clutch slave and/or master cylinder could be leaking internally (no visible external leak) or there could be air in the clutch hydraulic system that will have to be bled out. There are other mechanical causes of the clutch pedal going to the floor but in your circumstances that hydraulic circuit should be looked at first. If you desire a diagnostic, and repair of this issue, right at your location, please request a clutch system inspection. If you request that inspection, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I have a bad oxygen sensor, bad power steering sensor, and a bad cam shaft sensor? Should I replace any of them?
ANSWER : When you say you have three bad sensors I can only assume you have had them tested and the end result is three bad sensors. If they tested bad then they should be replaced. The power steering sensor senses the load of the steering on the engine so it can raise the idle during parking maneuvers. The O2 sensor is used for fuel control and it may effect engine power and fuel mileage. The camshaft sensor cay cause no starts, engine running problems and all three will turn on the check engine light.
