Abstract
A planetary gear change-speed transmission for vehicles, especially an automatically shifting change-speed transmission for motor vehicles in which a frictional engaging device and a free-wheeling device are arranged at the planetary gear set coordinated to the output and in which the frictional engaging device is actuatable by an actuating piston that is arranged in an annular cylinder of a housing part, which simultaneously takes over the free-wheeling support; the output shaft drives a controller whose feed and discharge lines are transferred into the transmission housing by means of a sleeve-like extension at the controller; a support flange is inserted into the transmission housing from the input side thereof and is secured at an annular flange of the transmission housing while a sleeve portion of the support flange facing the input is provided at its inner circumference with the transfer means for the pressure medium lines to and from the controller.
