Abstract
A method is provided for shifting a transmission having an input member, an output member, at least four planetary gear sets, a plurality of coupling members and a plurality of torque transmitting devices. At least one of the torque transmitting devices is a dog clutch or a band clutch. The method includes applying a torque transmitting mechanism to interconnect a first member of a planetary gear set with another member of a planetary gear set or a stationary member. The method also includes applying the dog clutch or band clutch to interconnect a second member of a planetary gear set with another member of a planetary gear set or the stationary member, after the first torque transmitting mechanism is applied. After the dog or band clutch is applied, the torque transmitting mechanism is released.
