Abstract

A compact five-speed transmission planetary hear train includes a first, second, third, and fourth planetary gear sets between an input and an output as well as first, second, and third brakes and first, second and third clutches. The first, second and third brakes and first, second and third clutches are selectively actuatable to provide five different forward speeds and four different reverse speeds between the input and the output.
