Abstract
An automatic transmission includes a first planetary gear set; a second planetary gear set; a third planetary gear set; an input shaft; an output shaft; and five friction elements. The five friction elements include a first friction element adapted to selectively connect a first ring gear with a second carrier, a second friction element adapted to selectively connect the first ring gear with the second rotating member, a third friction element adapted to selectively connect the second carrier with a third ring gear, a fourth friction element adapted to selectively stop a rotation of the third ring gear, and a fifth friction element adapted to selectively connect the first sun gear with the second carrier. Each of at least seven forward speed-ratios and one reverse speed-ratio is achieved by an engaged state of two friction elements selected from the five friction elements.
