AUTOMATIC TRANSMISSION ABSTRACT The principal components of this transmission include a pump, a turbine, a primary planetary gear set, a secondary planetary gear set and a compound planetary gear set. In one embodiment the compound planetary gear set has a compound planet gear element with two planet gears connected to each other on each planet shaft. The largest planet gear engages a ring gear and a first sun gear and the smaller planet gear engages a direction reversing planet idler gear which engages a second sun gear. The ring gear of the compound planetary gear set is preferably connected to the ring gear of the primary planetary gear set. The second sun gear is preferably connected to the ring gear of the secondary planetary gear set. The first sun gear is preferably connected to the sun gear of the primary planetary gear set and to the planet carrier of the secondary planetary gear set. Overrunning clutches are preferably provided to prevent the sun gear of the secondary planetary gear set from rotating faster than the pump and to prevent the compound planet carrier from rotating in a negative direction. Alternative embodiments are disclosed and claimed.
