Abstract
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.
