1. A planetary gear train of an automatic transmission for a vehicle, comprising:
an input shaft configured for receiving torque of an engine; an output shaft configured for outputting changed torque; a first planetary gear set having first, second, and third rotation elements; a second planetary gear set having fourth, fifth, and sixth rotation elements; a third planetary gear set having seventh, eighth, and ninth rotation elements; a first rotation shaft including the first rotation element and selectively connectable to a transmission housing; a second rotation shaft including the second rotation element and directly connected to the input shaft; a third rotation shaft including the third rotation element and the seventh rotation element; a fourth rotation shaft including the fourth rotation element and selectively connectable to the first rotation shaft and the second rotation shaft; a fifth rotation shaft including the fifth rotation element and selectively connectable to the third rotation shaft; a sixth rotation shaft including the sixth rotation element and the eighth rotation element and directly connected to the output shaft; and a seventh rotation shaft including the ninth rotation element, and selectively connectable to the fifth rotation shaft or selectively connectable to the transmission housing. |
