ABSTRACT:
A powertrain used for a 5-speed automatic transmission. The powertrain includes a first compound planetary gearset and a second compound planetary gearset. The first compound planetary gearset includes first and second simple planetary gearsets having first, second, third and fourth operating elements. The second compound planetary gear unit includes third and fourth simple planetary gearsets having fifth, sixth, seventh and eighth operating elements. The fifth operating element acts as an output element, and the first operating element acts as an input element. The fifth and sixth operating elements are variably connected to the second operating element, and the seventh operating element is fixedly connected to the fourth operating element. Clutches are disposed to variably connect the fifth and sixth operating elements to the second operating element. Brakes are interposed between the fourth and eighth operating elements and a transmission housing.
