Your car will switch gears through the clutch and assisting mechanisms. Without switching gears, your car wouldn't be drivable. This is why you need to be sure you are able to catch on to the beginning signs of clutch problems. By catching issues early on, you will hopefully be able to have the problem fixed right away, so you won't have to go through the troubles that come with suddenly not being able to use your car. Here are some signs that you are going to want to be aware of that might be telling you to get your car in to have the clutch checked out.
The clutch pedal doesn't feel right
If you have owned your car for a while, then you should immediately recognize when something is off with the way the clutch pedal feels. Otherwise, there are some things that should get your attention about the pedal, even if you aren't all that familiar with the car. The pedal may vibrate under your foot, it may have a spongy or even a sticky feeling to it as well. Any of these things should lead you to take the car in to have the clutch checked out.
There is a grumbling sound
When you press down and you hear a grumbling sound, or even a squeaking noise, then these are also a couple of signs that you are likely having problems with your car's clutch that you need to have it seen for.
There are problems with movement
If you can get the car to sound like it should be reaching that next gear with the engine roaring, but you can't get the car to accelerate the way that it should, then you need to get the car in right away. Also, you want to take it right in if you are suddenly having a hard time getting it to shift gears. The clutch slipping will cause the car to lose its acceleration in the middle of driving it, and you want to also take the car in for this.
If you have any reason to believe that there is an issue with your clutch, then the very best thing that you can do is to just take it to a clutch repair shop and get it looked at. If nothing is wrong, you'll feel better knowing that, and if something is wrong, then you'll be glad you can have the problem fixed sooner.
