Mobil ATF 3309
Mobil ATF 3309 is an exceptionally high-performance automatic transmission fluid engineered to meet the requirements of modern slip-controlled lock-up automatic transmissions. Formulated using advanced base oils and a carefully balanced additive system, Mobil ATF 3309 delivers excellent lubrication performance, smooth shifting and long-lasting protection under a wide range of operating conditions. The formulation is specifically designed to meet original equipment manufacturer specifications for transmissions requiring JWS 3309-type fluids.
One of the key advantages of Mobil ATF 3309 is its excellent frictional performance. The fluid is engineered with controlled friction characteristics that ensure smooth and efficient power transfer across all normal operating temperatures. This helps eliminate transmission shudder and provides improved vehicle drivability, particularly in modern automatic transmissions with lock-up clutch systems.
Mobil ATF 3309 also delivers outstanding wear protection. The advanced additive system helps form a durable lubricating film between moving transmission components such as gears, bearings and clutch systems. This reduces wear and helps extend the service life of transmission components, ensuring reliable performance over extended service intervals.
Another important benefit of Mobil ATF 3309 is its strong resistance to thermal degradation and oxidation. Automatic transmissions can operate under high temperatures, particularly in demanding driving conditions. Mobil ATF 3309 is formulated to resist breakdown at elevated temperatures, helping maintain fluid integrity and prevent the formation of harmful deposits. This contributes to longer fluid life and consistent transmission performance.
Mobil ATF 3309 also offers excellent viscosity stability. The fluid maintains consistent viscosity across a wide temperature range, ensuring reliable lubrication performance at both low and high temperatures. This helps prevent excessive thinning at high temperatures and ensures sufficient fluid flow during cold starts. The fluid also provides resistance to foaming and strong protection against rust and corrosion, helping maintain efficient transmission operation.
Mobil ATF 3309 is recommended for use in automatic transmissions requiring fluids meeting JWS 3309 or GM 9986195 specifications. It is also suitable for applications requiring Toyota T-IV, T-III or T3 fluids, as well as certain Ford and Audi transmission requirements. The product is designed to deliver reliable performance in a wide range of passenger vehicle automatic transmission systems.
Physical characteristics include a kinematic viscosity of approximately 33 mm²/s at 40°C and 7.1 mm²/s at 100°C, with a viscosity index of around 181. Mobil ATF 3309 has a density of approximately 0.852 g/cm³ at 15°C, a flash point greater than 185°C and a pour point below −45°C. The fluid also provides a Brookfield viscosity of approximately 13,000 mPa·s at −40°C and is red in colour, supporting reliable lubrication performance and smooth transmission operation across a wide range of operating conditions.
