ABSTRACT:
A gear train for changing the rotational speed of an input shaft to transmit the resultant rotation to an output shaft consists of single pinion type first and third planetary gear sets and a double pinion type second planetary gear set. Ring gears of these three planetary gear sets are normally or selectively interconnected to each other, a carrier of the first planetary gear set is normally or selectively connected to a sun gear of the third planetary gear set, a sun gear of the first planetary gear set is normally or selectively connected to a sun gear of the second planetary gear set, and the sun gear of the second planetary gear set is normally or selectively connected to the carrier of the first planetary gear set, whereby at least five forward speeds and one reverse are permitted to be set.
