Abstract
A hydraulic engagement apparatus for automatic transmissions includes a high clutch and a reverse clutch disposed adjacent to each other so as not to axially overlap with each other, each clutch including drive plates engaged with an inner surface of a clutch drum. When engaged, the high clutch and the reverse clutch serve to transmit rotation of an input shaft to a high-clutch hub and a reverse-clutch hub, respectively. A high-clutch piston and a reverse-clutch piston are arranged to axially spaced relative to each other, and to be movable with respect to the drive plates of the high clutch and the reverse clutch.
