Abstract
In an automatic transmission a low and reverse brake is arranged at an end portion of a transmission casing spaced from an inner surface of a side cover of the transmission. A cylinder chamber for receiving a piston of the low and reverse brake is formed integrally with the side cover as well as a second chamber, radially inward of the cylinder chamber for accommodating a clutch drum of a high clutch mounted proximate the low and reverse brake.
