Mobil 1 Automatic Transmission Fluid - 1 Quart (Pack of 12)

Mobil ATF 3309 is a high-performance lubricant that meets the original equipment manufacturer's specifications for use in certain slip-controlled lock-up automatic transmissions. It is recommended for use in transmissions requiring fluids of JWS 3309 or GM 9986195 quality levels, as well as for service fill applications where Toyota T-IV or T4, T-III or T3 are called for. Users should refer to the owner's manual for proper fluid requirements.

The unique formulation of Mobil ATF 3309 is designed to provide excellent lubrication of transmissions in specified slip-controlled lock-up automatic transmissions. These outstanding performance capabilities translate into significant operational benefits, including:

Excellent lubricating characteristics for quiet operation and smooth shifting in approved transmissions: The fluid's unique formulation helps ensure smooth and efficient transmission of power across all normal temperature ranges, contributing to a quiet and comfortable driving experience.

Controlled friction properties: Mobil ATF 3309 has carefully controlled friction properties, which help to control transmission shudder and provide excellent vehicle drivability.

Extended transmission life: The fluid's excellent wear control properties help to extend the life of the transmission, saving users time and money on maintenance and repairs.

Long fluid life: The fluid's excellent oxidation resistance contributes to its long lifespan, reducing the need for frequent fluid changes and further enhancing the cost-effectiveness of the product.

Excellent viscosity stability: Mobil ATF 3309 maintains a high viscosity index, ensuring adequate lubrication without excessive thinning in severe high-temperature service or thickening at low starting temperatures.

Additional benefits include resistance to foaming, super protection against rusting and corrosion, and compatibility with synthetic rubber seal materials.

Automatic transmissions should be checked for proper fluid levels at regular intervals, and the fluid should be changed at manufacturer-recommended intervals. However, this may vary due to the vehicle's operating conditions, and some manufacturers recommend more frequent changes under severe driving conditions, such as heavy traffic, hot weather, and trailer pulling.
