For those of you who aren't mechanically-savvy, you probably still understand that transmission problems are among the most expensive repairs required for your vehicle. That's because your transmission is a complex system of gears that transmit mechanical power to your engine, ultimately determining the rate of speed you travel.

The transmission works with the engine to provide power to you car’s wheels. Whether automatic or manual, the transmission plays a major role in the overall performance of your car. Make sure to check it at the first sign of problems.

Tire rotation refers to the regular practice of switching the position of each tire on the car.

The steering and suspension systems are key safety-related systems that largely determine your car’s ride and handling. Have these systems checked regularly, at least once a year and usually with a wheel alignment.

The primary function of your cars suspension and steering systems is to allow the wheels to move independently of the car, while keeping it "suspended" and stable.
