Abstract
A transmission (G) is provided with four planetary gear sets (P, P, P, P), several shafts (W-W) and a first, second, third, fourth and fifth shift element (B, B, K, K, K), the selective meshing of which brings about different transmission ratio relationships between a transmission input shaft (GW) and a transmission output shaft (GW). The transmission (G) includes a sixth shift element (K), through which the fifth shaft (W) is connectable to the sun gear (So-P) of the fourth planetary gear set (P), either directly or through the second shift element (B), and whereas the fourth shaft (W) is connectable through the fourth shift element (K) with the sun gear (So-P) of the fourth planetary gear set (P), either directly or through the second shift element (B).
