Abstract
An automatic transmission for motor vehicles comprising three interconnected planetary gear units, two rotating friction clutches and four friction brakes providing six optimized forward gear ratios and a reverse ratio, all assembled into a compact package no larger than the current four-speed automatic transmissions. This invention preferably utilizes two multi-plate rotating clutches and special friction force balanced brake bands that allows self-synchronized ratio shifts without creating any side loading of associated band drums.
