PURPOSE: A planetary gear train of an automatic transmission for a vehicle is provided to improve power transmission performance by implementing a transmission lever having an excellent operating condition of a friction member. CONSTITUTION: An input shaft(IS) receives the rotation power of an engine. An output shaft(OS) outputs the shifted rotation power. A first planetary gear set(PG1) reversely outputs the rotation power selectively inputted. A second planetary gear set(PG2) forwardly reduces the inputted reverse rotation power. Eight rotation members(TM1-TM8) connect two or more rotation elements. Six friction members(C1-C4,B1-B2) are composed of a clutch and a brake. [Reference numerals] (AA) Input; (BB) Output |
