A spring pack for a transmission includes first rotatable piston and a second rotatable piston. The first rotatable piston includes a first retainer plate, and the second rotatable piston includes a second retainer plate. The spring pack further includes a tabbed retainer plate that is stationary with respect to the first piston and the second piston and also includes a set of biasing members with a first subset of biasing members and a second subset of biasing members. The first subset of biasing members is disposed between the first retainer plate and the tabbed retainer plate, and the second subset of biasing members is disposed between the second retainer plate and the tabbed retainer plate. As the first and second pistons are activated, they stroke independently of each other as each retainer plate compresses its respective subset of biasing members against the tabbed retainer plate.
