  • What is the difference between automatic and manual cars?

    Q: What is the difference between automatic and manual cars?

    A: The difference between manual and automatic cars is that manual cars use manual transmission whereas automatic cars use automatic transmission. In a manual car, the driver is responsible for shifting the gears as the car's speed changes, but in an automatic car, changing gears happens automatically.

  • 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.

  • What causes a clutch to burn out?

    Q: What causes a clutch to burn out?

    A: The clutch can burn out over time in a manual transmission car if the driver makes a habit of riding the clutch, using the clutch to keep the car in one place on hills or using the clutch to slow down rather than using the brakes. It is also possible to burn out the clutch suddenly by trying to do a "burnout."

  • Q: How do four-wheel drive cars work?

    A: A four-wheel-drive car uses a transfer case to split the engine's power evenly between front and rear axles rather than supplying all the energy to one set of drive wheels. This provides better grip and control in certain surface conditions, since all four wheels are powered. These systems are often paired with traction control systems in order to maintain power, even when one wheel spins freely.

  • Q: What can you do with a gear ratio calculator?

    A: A differential gear ratio calculator allows you to determine the effects of changing tire size, gear ratio and speed on engine RPMs in rear- and four-wheel drive vehicles. The differential gear ratio impacts vehicle speed, power and fuel economy and can be changed to increase one factor to the detriment of the others. Numerically higher ratios provide more low-end power, while numerically lower ratios give more top-end speed and fuel economy.

  • Q: Why would a manual transmission auto not have a dip stick?

    A: Manual transmission autos do not have dip sticks because the fluid must be checked using the fill plug that is found by hoisting the vehicle on a lift or on jack stands. Unlike the ease of popping the hood and just checking the fluid level, the procedure is more complicated and can be messy. The check should only be done by a professional unless the owner is car savvy and has the proper equipment.

  • What are the pros and cons of factory-rebuilt transmissions?

    Q: What are the pros and cons of factory-rebuilt transmissions?

    A: A major advantage of factory-rebuilt transmission is cost, since remanufactured transmissions can cost far less than buying new transmissions. Inversely, a major disadvantage to consider when buying a rebuilt transmission is that the warranty on the transmission is often shorter than the warranty on a new transmission.

  • Q: Why does my car idle high?

    A: There are many reasons a car idles fast, but one common reason is a vacuum leak. Older muscle cars have only two or three vacuum hoses, making finding the leak easy. Newer vehicles have complex vacuum systems to reduce emissions, so leaks are more difficult to find. Popular Mechanics suggests spraying carburetor cleaner on a suspected leak and listening for the engine speed to increase.
