Abstract
A gear train of an automatic five-speed transmission includes an input shaft for transferring the power of an engine via a torque converter, a first-speed drive gear mounted on the input shaft, a first-speed driven gear meshed with the first-drive gear to produce a reduced speed ratio, an output shaft for transferring the power received from the first-speed driven gear to a differential gear, a planetary gear unit connected with the input shaft, a first friction element selectively connected with the input shaft and output shaft for producing a first reduced speed ratio, a second friction element selectively connected with the input shaft for transferring the input power through a first power transfer member to a first sun gear of the planetary gear unit to produce a second reduced speed ratio, a third friction element selectively connected with the input shaft for transferring the input power through a second power transfer member to the planetary carrier of the planetary gear unit serving as an input element, and a fourth friction element for gripping a third power transfer member to employ as a reacting element a second sun gear receiving the rotational force of the first sun gear of the planetary gear unit serving as an input element.
