ABSTRACT:
With the automatic transmission10-1for vehicle according to the present embodiment, since multistage transmission of eight forward gear stages can be obtained by means of four sets of planetary gear sets12, 16, 18and20, four clutches C1through C4and three brakes B1through B3, the transmission can be fabricated to be light in weight and made compact, wherein the mountability thereof in a vehicle can be improved. Further, as has been made clear in FIG.1(b), since speed change in the respective gear stages can be carried out only by a shifting action of any two of the clutches C1through C4and brakes B1through B3, the speed change control can be facilitated and it is possible to prevent a shock to the transmission from occurring.
