Abstract

A transmission having planetary gearsets (RS1, RS2, RS3, RS4, RS5). Elements (ST2, ST4) of gearsets (RS2, RS4) form input and output shafts, respectively. Element (SO1) of gearset (RS1) couples element (HO5) of gearset (RS5) and can be immobilized by shift element (A). Element (ST1) of gearset (RS1) couples element (HO4) of gearset (RS4). Element (HO1) of gearset (RS1) can be immobilized by shift element (B). Elements (SO4, ST2) of gearsets (RS4 RS2) can connect by shift element (C). Elements (HO2, SO3, SO5) of gearsets (RS2, RS3, RS5) couple and can couple element (SO4) of gearset (RS4) by shift element (E). An element of gearset (RS4) is connected to an element of gearset (RS3), while another element of gearset (RS4) can be connected by shift element (D) to another element of gearset (RS3). Elements (SO2 ST5) of gearsets (RS2, RS5) are connected and can be immobilized by shift element (F).
