Abstract
A transmission and a clutch assembly for a vehicle are disclosed. The clutch assembly includes a housing defining a cavity presenting an interior surface. The interior surface defines a pocket along a longitudinal axis. The clutch assembly further includes a piston disposed in the pocket and movable between an initial position and a final position relative to the pocket along the longitudinal axis. The piston includes a plurality of flanges extending outwardly away from the longitudinal axis. The clutch assembly also includes a biasing member attached to the interior surface of the housing and engaging the piston to continuously bias the piston toward the initial position. The biasing member abuts the flanges of the piston to prevent rotation of the piston about the longitudinal axis as the piston moves between the initial and final positions along the longitudinal axis.
