Abstract
To simplify the hydraulic pressure supply passage to each clutch, an multistage automatic transmission comprises an input part and output part, three clutches, two brakes, and four planetary gear sets, where the first and fourth sets are of a single pinion type and the second and third of a double pinion type. The input and output parts and the planetary gear sets connect to each other and the clutches and brakes decouple components in such a way that enlargement as a whole of the transmission and the deterioration of the responsiveness of the shift control are controlled.
