A multispeed automatic transmission for motor vehicles has three planetary gear sets arranged in series, each having a ring gear, a planet gear support with planet gears, and a sun gear. Externally-controlled clutches and brakes are arranged to provide six forward and one reverse gear stages. To provide improved riding comfort and fuel economy, only five shifting components are required, and the construction of the transmission permits an especially short and economical structure and especially favorable planet gear speeds.

Automatic transmission having three planetary gear sets

An automatic multistage transmission for vehicles has an input shaft and two output shafts parallel to the input shaft and includes two gear stages which are capable of shifting by way of frictional engagement and other gear stages engagable by gear tooth engagement. In pull operation, the first transmission stage is constantly in engagement by means of a rotatably supported gear connectable through a first sliding bushing. The fixed gear of the first transmission stage is coupled through a reversing pinion to a reversing gear rotatably supported on one of the output shafts which can be connected through a second sliding bushing to the output shaft on which it is mounted.
