Abstract:
1. A transmission shifting element decelerator comprising: a first piston; a pressurized fluid configured to move the first piston in a direction perpendicular to a face of a clutch plate; and a second piston movably mounted within the first piston and configured to allow the pressurized fluid to move the second piston in the direction perpendicular to the clutch plate; a first spring connected between the first piston and the second piston and configured to resist movement of the second piston in a direction toward the clutch plate; and a second spring connected between the first piston and the second piston and configured to resist movement of the second piston in a direction away from the clutch plate, wherein a portion of the second piston extends outside of the first piston and engages the clutch plate before the first piston engages the clutch plate.
