Zusammenfassung:Four planetary gear sets, three rotating clutches, and two brakes can be arranged to produce eight forward speed ratios and a reverse speed ratio. The first and fourth gear sets can be substantially coplanar with each other, and the second and third gear sets can be substantially coplanar with each other. The lowest forward speed ratio could be suitable for use as a special purpose low range ratio, while the remaining seven forward ratios can provide adequate span for normal driving.
