Shell Spirax S6 ATF 134ME
Shell Spirax S6 ATF 134ME is a premium performance automatic transmission fluid specifically developed for the latest generation of Mercedes-Benz passenger car automatic transmissions. Formulated using high-quality hydrocracked synthetic base oils combined with advanced additive technology, the fluid is engineered to provide outstanding durability, smooth shifting performance and reliable protection in modern fuel-efficient transmission systems. The lubricant has been developed as both an initial-fill and service-fill fluid for Mercedes-Benz 7-speed NAG2FE+ automatic transmissions used in a range of passenger vehicles.
One of the key advantages of Shell Spirax S6 ATF 134ME is its superior friction durability. Automatic transmissions rely on carefully balanced friction characteristics to ensure smooth engagement of clutch packs and consistent gear changes. The advanced additive technology in Spirax S6 ATF 134ME maintains stable friction performance throughout the service life of the fluid. This ensures reliable gear shifting, improved transmission responsiveness and enhanced driving comfort under a wide range of operating conditions.
Shell Spirax S6 ATF 134ME also offers excellent thermal and oxidative stability. Automatic transmissions operate under demanding conditions where high temperatures and mechanical stress can accelerate fluid degradation. The advanced synthetic formulation resists oxidation and thermal breakdown, helping prevent deposit formation and maintain transmission cleanliness. This helps ensure consistent transmission performance and long fluid service life even under severe operating conditions.
Another important benefit of Shell Spirax S6 ATF 134ME is its excellent shear stability. The formulation maintains stable viscosity characteristics throughout the operating temperature range, ensuring reliable lubrication of gears, bearings and hydraulic control systems. This stability helps maintain transmission efficiency and supports consistent hydraulic control performance during both cold start conditions and high-temperature operation.
Shell Spirax S6 ATF 134ME has been specifically engineered to support modern fuel-efficient transmission designs used by Mercedes-Benz. The lubricant contributes to overall drivetrain efficiency while providing reliable protection against wear and component damage. It is designed to meet the precise requirements of the NAG2FE+ 7-speed automatic transmission architecture used in many Mercedes-Benz passenger vehicles.
The fluid carries official MB-Approval 236.15 and is mandatory for use in Mercedes-Benz NAG2FE+ 7-speed automatic transmissions. It should not be used in older Mercedes-Benz 5-speed or earlier 7-speed transmissions requiring fluids with MB-Approval 236.10, 236.12 or 236.14. Physical characteristics include a kinematic viscosity of approximately 19 mm²/s at 40°C and 4.4 mm²/s at 100°C with a viscosity index of approximately 147. The fluid has a density of approximately 845 kg/m³ at 15°C, a flash point of approximately 185°C and a pour point of approximately –51°C. The product is also dyed blue for identification purposes, supporting correct application and service procedures.
