Typically, a clutch on a manual transmission will last between four and seven years, depending on where and how the car is driven. At the end of its life, you’ll start seeing signs of a slipping clutch. For instance, you may notice that you are getting much poorer gas mileage. You may also notice the need to downshift more when going up hills.
Other signs of a slipping clutch include an aggravated revving noise when you accelerate. The clutch may also begin to feel stiff and require more force to depress it. Unless you’re a mechanic, I would not advise trying to fix such a vital piece of your car by yourself. Take it into a clutch repair Seattle shop and have the professionals have at it.
