Abstract
A planetary transmission has a fluid applied brake for a low speed ratio and a fluid release spring applied clutch for a high speed ratio. The clutch apply springs respond to a centrifugally actuated member such that below a predetermined output speed, the springs are not compressed sufficiently to cause engagement of the clutch. The clutch is maintained disengaged by the fluid pressure which engages the brake regardless of output speed. The interchange of the brake and clutch are selectively controlled by controlling the fluid pressure source.
