  "textContent": "The invention relates to an automatic transmission with four planetary gear sets (RS1, RS2, RS3, RS4) and seven switching elements (C, B, D, E, A, M, H) for switching various transmission ratios between an input shaft (AN) and an output shaft (AB). The first and second planetary gear sets (RS1, RS2) form a pre-transmission gear set (VS) that can be connected to the input shaft (AN), the third and fourth planetary gear sets (RS3, RS4) form a main gear set (HS) connected to the input shaft (AN) and output shaft (AB). Pre-transmission gear set (VS) and main gear set (HS) are connected to one another via exactly one connecting shaft (W). The first, second, third, fourth and fifth switching elements (C, B, D, E, A) are permanently directly connected to the pre-transmission gear set (VS), while the sixth and seventh switching elements (M, H) are permanently directly connected to the main gear set (HS). It is proposed that the pre-transmission gear set (VS) and main gear set (HS) each have five rotatable shafts (wv1, wv2, wv3, wv4, wv5; wh1, wh2, wh3, wh4, wh5).",
