Brand New M11 DSI6AT B2 Brake Piston OE 0511624044 for Ssangyong Korando Actyon & Geely DSI6AT Gearbox Replacement Parts

This is brand new B2 brake piston assembly for M11 DSI6AT six-speed automatic transmission, OEM number 0511624044. The DSI M11 6-speed gearbox was originally developed by Australian DSI company, matched for Ssangyong diesel vehicles and early Geely passenger cars equipped with imported DSI6AT gearbox.

As core hydraulic control component inside transmission, the B2 brake piston controls combination and separation of B2 clutch pack via hydraulic oil pressure. Damaged, deformed or aging piston will directly cause shifting delay, gear slipping during acceleration, driving shudder and internal transmission oil leakage. Our newly produced piston completely fixes above common transmission malfunctions.

Important Tip: Later Geely models using Aisin 6AT or DCT dual clutch transmission are NOT applicable.

Premium Aviation Grade Aluminum Alloy Material:

Made of high-density aluminum alloy via CNC precision machining, outstanding resistance against high temperature, ATF corrosion and hydraulic compression deformation, long service life under frequent shifting.

Strictly Produced per OEM Dimension 0511624044:

1:1 original size design, direct plug-in installation without any casing modification, perfect assembly clearance same as original factory standard.

Fix Typical Gearbox Failure Efficiently:
