Planetary Gear Set Replacement

In an automatic transmission system, the planetary gear set is responsible for every gear ratio that your vehicle uses to convert the speed and power of the engine into the rotating power, or torque, that your tires need to move your vehicle.

A car not moving, or one that experiences a loss of power, could mean a failed planetary gear set. With lubrication via transmission fluid, provided by the automatic transmission fluid pump, it works like a heart to pump fluid through the automatic transmission system. The teeth of the planetary gears are able to properly run and create every different gear ratio. Every automatic transmission system holds two whole planetary gear sets.

Also known as epicyclic gearing, the planetary gear set consists of mounted gears that revolve around a center gear and produce torque, or rotational force. It sends the force through the output shaft to the wheels. With consistent lubrication with transmission fluid, the gears should not grind down as quickly. However, should you hear a grinding or other abnormal noise, we recommend a visit to 12th Street Auto Care Center, a trusted Sioux Falls, SD auto repair shop. Our ASE-certified mechanics can offer a planetary gear set replacement, repair and inspection, regardless of your budget.
