Abstract
The automatic transmission of the present invention prevents fluctuation of torque transmission through a band brake. In the hydraulic operator for the band brake, a resilient elastic cushion is provided between a rod abutting one end of the band of the band brake and a piston. Any slippage between the band and drum of the band brake will result in oscillation of the rod. However, the elastic cushion absorbs oscillation of the rod, thereby isolating the piston from that oscillation.
