Zusammenfassung:	An automatic transmission includes a first planetary gear set including a first sun gear, a first pinion, a second pinion, and a common ring gear, and includes a second planetary gear set including a second sun gear, the second pinion, and the common ring gear. The transmission includes a third planetary gear set including a third sun gear, a third pinion, and a ring gear of the third set, and includes a fourth planetary gear set including a fourth sun gear, a fourth pinion, and a ring gear of the fourth set. The transmission also includes a first planetary carrier rotatably supporting the first pinion, the second pinion, and the third pinion. The common ring gear is directly connected to the ring gear of the fourth set, and a second planetary carrier rotatably supports the fourth pinion and is directly connected to the ring gear of the third set.
