Patent ID: 7294087

Claim:
An automatic transmission comprising: a mechanical reduction gear connected to an input shaft that generates a decelerated rotation smaller than a rotation of the input shaft from a decelerated rotating member; and a compound planetary gear for shifting with a first element, a second element, a third element, a fourth element, and a fifth element, wherein: the first element is capable of being connected to the decelerated rotating member via a third clutch and capable of being stopped from rotating by a first brake, the second element is capable of being stopped from rotating by a second brake, the third element is capable of being stopped from rotating by a third brake, with either the second element or the third element capable of being connected to the input shaft via a second clutch, the fourth element is connected to an output shaft, the fifth element is capable of being connected to the decelerated rotating member via a first clutch, and at least seven forward speed ratios can be established, wherein (1) a first speed is established by engagement of the first clutch and the third brake, (2) a second speed is established by engagement of the first clutch and the second brake, (3) a third speed is established by engagement of the first clutch and the first brake, (4) a fourth speed is established by engagement of the first clutch and the third clutch, (5) a fifth speed is established by engagement of the first clutch and the second clutch, (6) a sixth speed is established by engagement of the second clutch and the third clutch, and (7) a seventh speed is established by engagement of the second clutch and the first brake.
