  • What causes a heavy clutch pedal?

    Q: What causes a heavy clutch pedal?

    A: There are many causes of a heavy clutch pedal; one of the most common causes is a worn out clutch. When the clutch is starting to wear out, it does not spin at the same speed as the flywheel. This creates friction, which requires pushing harder on the clutch pedal to change gears. There are also a few other auto parts that cause a heavy clutch pedal.

  • Q: How can you identify a manual transmission?

    A: Distinguish the basic type of a transmission from the configuration of a vehicle's shift lever assembly or lack thereof. Identification of the specific model of transmission in a given vehicle usually requires inspecting the transmission itself for an identifying code stamped on the transmission case. Information about the vehicle's make and model and the general shape of the transmission case can also help narrow down what specific transmission is installed in a given vehicle.
