Product Description

Shell Spirax S6 ATF D971 is a high-performance, fully synthetic automatic transmission fluid designed specifically for modern Mercedes-Benz 9-speed automatic transmissions (9G-Tronic / NAG3). It is engineered with premium synthetic base oils and advanced additive technology to deliver exceptional shear stability and thermal protection under demanding conditions. The fluid ensures smooth, fuel-efficient power transfer and optimal friction durability throughout its operational lifespan. Its low-viscosity formulation significantly contributes to reduced transmission power losses and improved overall vehicle fuel economy. Typical physical parameters include a kinematic viscosity of 17.5 mm²/s at 40°C, 4.2 mm²/s at 100°C, a density of 835 kg/m³ at 15°C, a flash point of 190°C, and a pour point of -54°C. It holds full MB-Approval 236.17, making it the primary service fill fluid for 9G-Tronic transmissions.
