Abstract: An assembly for use in a transmission of a motor vehicle includes a planetary gear set that defines an axis of rotation and includes a planetary carrier member, the planetary carrier member having at least one window. A piston is disposed on a first side of the planetary gear set and a clutch pack is disposed on a second side of the planetary gear set opposite the first side. An interplanetary actuator is in contact with the piston and the clutch pack and is slidably disposed in the window of the planetary carrier member. Actuation of the piston in turn translates the interplanetary actuator to engage the clutch pack.
