The piston is a component that controls the shifting and engagement of gears within the planetary gear set of an automatic transmission. It is designed to apply or release pressure on various clutch packs or brake bands to achieve the desired gear ratios and enable smooth shifting. The piston is controlled by hydraulic pressure generated by the transmission's hydraulic system. Hydraulic fluid is directed to the piston through valves and solenoids, activating the clutch packs or brake bands and initiating gear shifts.Attributes:• Provide high strength, wear resistance, and durability.• Help to prevent fluid leakage and ensure reliable engagement and disengagement. Applications:The piston is used to facilitate the engagement and disengagement of clutch packs or brake bands, enabling smooth gear shifting and gear ratio control.
