  "text": "For all other transmission types with more complex split power flows and/or planetary gear sets (e.g. a conventional automatic planetary transmission), the following simplified method shall be used to determine the torque dependent efficiency. The method covers transmission systems composed of ordinary, non-planetary gear sets and/or planetary gear sets of ring-planet-sun type. Alternatively the torque dependent efficiency may be calculated based on VDI Regulation No. 2157. Both calculations shall use the same constant gear mesh efficiency values defined in 3.1.1.2.\nIn this case, for each indirect gear g, the following steps shall be performed:",
