Shell Spirax S5 ATF X
Shell Spirax S5 ATF X is a premium performance automatic transmission fluid developed using advanced synthetic technology base oils and a carefully balanced additive system. The fluid is designed to meet the requirements of multiple vehicle manufacturers and transmission designs, making it suitable for a wide range of passenger cars and heavy-duty vehicles. Its advanced formulation provides smooth shifting performance, reliable protection and extended fluid life in demanding automatic transmission applications.
One of the key advantages of Shell Spirax S5 ATF X is its advanced friction-modified formulation. Automatic transmissions rely on precise friction control to ensure smooth engagement of clutches and bands during gear changes. The carefully engineered friction characteristics of Spirax S5 ATF X provide consistent and reliable shifting performance while minimising transmission shudder and shift shock. This helps deliver smooth, trouble-free operation and improved driver comfort across a wide range of vehicle types.
Shell Spirax S5 ATF X also offers exceptional oxidation resistance and thermal stability. Automatic transmission fluids can be exposed to high temperatures and mechanical stress during operation, which may lead to fluid degradation and deposit formation over time. The high-quality synthetic base oils combined with advanced oxidation inhibitors help resist oil breakdown and maintain fluid cleanliness. This ensures the transmission remains free from harmful deposits and supports reliable long-term operation.
Another important benefit of Shell Spirax S5 ATF X is its excellent shear stability and viscosity control. The formulation incorporates a specialised viscosity index improver designed to minimise viscosity changes across a wide operating temperature range. This allows the fluid to maintain stable lubrication performance during both cold start conditions and high-temperature operation, ensuring consistent protection for gears, bearings and hydraulic control components within the transmission.
Shell Spirax S5 ATF X also provides dependable wear protection for critical transmission components. The advanced additive system helps protect gears, bearings and hydraulic components from wear and surface damage. By maintaining a durable lubricating film between moving parts, the fluid helps extend the operational life of transmission components and maintain reliable drivetrain performance.
The fluid is suitable for a wide range of applications including passenger car automatic transmissions, heavy-duty automatic transmissions, power steering systems and certain hydraulic systems requiring an automatic transmission fluid.
