How Long Does Clutch Fluid Last?

How long does clutch fluid last?
Experienced mechanics share their insights in answering this question :
Clutch fluid in most vehicles is the same as what is used in most brake systems, brake fluid. The fluid over time will get contaminated with moisture, dirt, debris, and internal clutch master and slave cylinders wear materials. All of these contaminants will start to cause excessive wear to the clutch master and slave cylinder seals if not removed. This can be done by flushing out the complete system with only new fresh brake fluid recommended by the manufacturer. Some manufacturers do not give any fluid change interval originally, but only will during replacement.

Most vehicles that give a recommended fluid replacement interval say that the clutch fluid should be replaced every 30,000 miles, or if the fluid has excessive debris.

We suggest you change the fluid: Every two years. If the fluid has dirt. If the fluid level goes down.
YOU SHOULD REPLACE BRAKE FLUID EVERY FEW YEARS

And the best way to find out how often to change brake fluid is to follow your manufacturer`s recommendations. Some manufacturers say you should replace your brake fluid every two years. Others recommend every three years, or every 45,000 miles.

Over time, your car`s brake fluid absorbs water content which can lead to brake failure. Vehicle manufacturers recommend that you change your brake fluid every two years so that your brakes work to their optimum performance.
Clutch fluid levels can drop over time through normal operation, but it`s important to rule out bigger problems. If it`s chronic and you`re having to refill often, you have a bigger problem.
Most brake fluid manufacturers state that a sealed bottle has no set expiration date. In a sense, the fluid doesn`t break down over time and offers the same level of performance even after years on the shelf.
Brake fluid lives in a sealed system and can survive for years, but moisture from the surrounding air can work its way in through hoses and other parts of the brake system.
While brake fluid doesn`t need to be replaced as often as many other fluids in your vehicle, it can go bad or run low.
A clutch should last you between 50,000 and 100,000 miles before you need to replace it. When their lifespan comes to an end, it`s vital to change your clutch as soon as possible as its vital to maintaining healthy performance of your vehicle.
Most clutches are designed to last approximately 60,000 miles before they need to be replaced. Some may need replacing at 30,000 and others can keep going well over 100,000 miles, but this is fairly uncommon.
Causes of clutch fluid leaks from the clutch system:

Worn master cylinder seals – Your car`s clutch master cylinder has seals that prevent fluid from leaking out. These seals will degrade over time, which may eventually resulting in them leaking brake fluid from above and around the clutch pedal.

Over time, your car`s clutch fluid may start to run low. You can check its level by examining the clutch reservoir. Clutch fluid should be topped up once it is reaching a low point. Although topping up the fluid is usually an easy task, a leak is a much more difficult problem to deal with.

Soft clutch, topped off clutch fluid reservoir and clutch pedal became firm/springing back on its own.
ANSWER : It is most common for the clutch hydraulic leak to be from a leaking clutch slave cylinder. You should have the clutch hydraulic system inspected by YourMechanic to see why the fluid is getting low. The fluid gets low anytime there is a leak in the system. You may need to have the clutch slave cylinder replaced. If the clutch master cylinder and slave cylinder are both need replaced then it is a good idea to have both the clutch master and slave cylinders replaced together as a pair.

Why would I keep getting air and fluid bleeding through the clutch system in my 2008 Infiniti G35
ANSWER : Hello. You more than likely have a bad clutch master cylinder. These will often have a seal failure on the back side of the cylinder which will either leak or suck in air. Both of these will cause this to occur. If there are not any leaks at the slave cylinder then the master cylinder needs to be replaced and bled.

New cars don’t have transmission fluid dipsticks Transmission fluid changing
ANSWER : That’s a very good question. The reason they have gone with no dipsticks is because they don’t want people messing with transmissions other there at the dealership. Some cars went through that a couple of decades ago. They make it a very involved, convoluted process all through, in order to change the fluid on these modern cars. They have special adapters you have to put. Some of them have to have scan computers in order to read the data and what’s in there, and then be able to change it. A lot of these companies claim that this new fluid is the "lifetime" fluid.

Most new use synthetic fluid can last a long time but any fluid is going to get dirty and wear out over time. I would change it at least every 80,000 – 100,000 miles but if you’ve got one that is really hard to change, you are better off hiring a mechanic to do it.

On some of the cars, it would be too hard for the do-it-yourself because of all that equipment you need. The professional mechanics already have that. Just call any good mechanic, like one from YourMechanic, and they will be able to perform a transmission fluid service for you.

What can you do to see how healthy a transmission is / how long it’ll last? How much do these tests tell you?
ANSWER : Some of the tests that could be performed to determine if a transmission is in good condition would be to first check the fluid level as you mentioned. If the fluid level is low or the condition of the fluid is sub par, I would recommend having the fluid changed. After checking the fluid, driving the vehicle with a variance of engine speeds will also help to determine if the vehicle’s transmission is performing properly. Other than these two tests, you can also check the vehicle with an OBD2 scanner to determine if any check engine light codes are present. Many times the trouble codes for the transmission will also cause the check engine light to be illuminated. If you would like to have your transmission inspected consider YourMechanic, as a certified mechanic can come to your home or office to inspect your transmission for you.

Clutch sticking to floor
ANSWER : It does sound like you have a hydraulic problem. First, I would check for external leaks. If none are found, the problem could be air in the system. This could be the result of not bleeding the system properly after flushing the old fluid. In this case, the next step would be to bleed the system of air. If after this, the release bearing still does not move when the clutch pedal is depressed, there is an internal sealing problem and the master/slave cylinder must be replaced. A trained professional, such as one from YourMechanic, can diagnose your clutch issue to let you know what repairs are necessary.

Master cylinder and clutch slave cylinder replaced
ANSWER : Unfortunately, using the same plastic clutch slave cylinder assembly the vehicle was manufactured with will cause the same results if the vehicle is abused. The plastic part is very strong, but cannot withstand the heat and pressure from hard driving. You may be able to do some research and find a higher performance part produced by an aftermarket company, as some companies specialize in manufacturing upgraded parts for higher performance. If you would like some assistance with this, one of the technicians from YourMechanic can come to your location to inspect the shaking problem and let you know what repairs are needed.

Why does my clutch pedal sink to the floor and dosent come back up?
ANSWER : Hi – there are 2 main causes for the clutch going all the way to the floor. First – check that the return spring on the clutch pedal is in place. Second – I see you bled the system – bleed the system again. This is how I would do it – use a short length of hose connected to the bleeder screw, run that hose into a cup half full with recommended fluid…fill the reservoir, then have one person pump the pedal while the other opens the bleeder screw and watches until NO BUBBLES come out (and makes sure the reservoir doesn’t run dry). Then close the screw fill the reservoir to the mark, and test her out. If you would consider, YourMechanic can send a certified technician to you and assist you in troubleshooting this clutch issue.
