ABSTRACT:
A shiftable roller clutch to replace the standard disk pack clutch in an automatic transmission is specifically designed to act cooperatively with the planet carrier, and to occupy a minimum of axial space within the transmission housing. The cage pilots on the outer surface of the cam race as it is shifted back and forth, and the actuator that moves the cage is axially aligned with the cam race, so that the total axial space taken up is minimized. The cam race also pilots on part of the planet carrier so as to maintain its concentricity therefrom.
