Abstract: A planetary gear train of a transmission for a vehicle is provided. The planetary gear train includes an input shaft that receives power of an engine and an output shaft that outputs power. Additionally, four planetary gear sets are provided each having three rotation elements. Various shafts then connect the rotation elements either directly or selectively. Accordingly, a gear shift stage appropriate to a rotation speed of an engine is implemented and operating noise of a vehicle is reduced by using a driving point in a low rotation speed range of the engine.
