When your car is experiencing transmission problems, it can be helpful to know about how your transmission works. In a car with an automatic transmission, there are many sophisticated components that are used to transfer power from the engine to the wheels. Among the most essential systems in any automatic transmission are the planetary gearsets. As your car transitions between speeds, the planetary gearsets are designed to help your transmission find just the right gear. Your planetary gearsets get their name due to their unique design, which mimics the solar system. Each planetary gearset has a main gear that is orbited by several secondary gears. Since many transmission problems originate in the planetary gearset, it is important to bring your vehicle to a transmission specialist at the first sign of an issue. From transmission replacement to basic repairs, your transmission shop near Silver Spring, Bethesda, and Rockville can provide you with a full range of services.
