Shaft () couples the carrier of gearset (P) and the ring gear of gearset (P) and couples, via brake (), a housing. Shaft () couples the sun gear of gearset (P) and, via clutch (), shaft (), which couples the sun gears of gearsets (P, P). Shaft () couples the carrier of gearset (P) and the ring gear of gearset (P) and, via brake (), the housing. Shaft () couples the ring gear of gearset (P) and, via brake (), the housing. Shaft () couples the carrier of gearset (P) and the ring gear of gearset (P). The output shaft couples the carrier of gearset (P).
