Introducing new additions to the Masuma lubricant range: automatic transmission fluids.
Regular replacement of transmission fluid is essential for any transmission, even if the manufacturer claims it is designed for a "lifetime fill." Over time, the fluid loses its properties due to high temperatures, oxidation, and contamination from wear particles. Replacing it improves transmission performance and significantly extends its lifespan.
Masuma offers a range of high-quality fluids for automatic transmissions:
- Planetary gear automatic transmissions (ATs): ATF 4–5 HV, ATF A6 HV, ATF 6–9 LV.
- Continuously variable transmissions (CVTs): CVTF J3, CVTF J2.
AT FLUIDS
MASUMA ATF 4–5 HIGH VISCOSITY
A fully synthetic, high-viscosity operating fluid designed for classic automatic transmissions (3–4, occasionally 5-speed) in American, Japanese, Korean, and European vehicles.
- Excellent frictional properties, high thermal resistance, and stability under extreme loads.
- Maintains fluidity at low temperatures, ensuring reliable transmission performance in winter.
- Safe for components made from copper and copper alloys.
- Promotes smooth gear shifts, reliable operation, and protects older, high-mileage transmissions from wear.
MASUMA ATF A6 HIGH VISCOSITY
A fully synthetic, high-viscosity operating fluid tailored for 6-speed automatic transmissions such as the Aisin TF60-SN, TF61-SN, TF62-SN, used in vehicles by VAG (09G, 09K, 09M), Volvo (TF-80SC), Land Rover (AWF21), and BMW (GA6F21WA).
- Delivers high thermal stability and durability under extreme conditions.
- Preserves fluidity in low temperatures for confident winter performance.
- Safe for copper-based components.
- Supports smooth gear shifts and enhances the longevity of older automatic transmissions.
MASUMA ATF 6–9 LOW VISCOSITY
A fully synthetic, low-viscosity fluid designed for modern multi-speed automatic transmissions in American, Japanese, Korean, and European vehicles.
- Reduces transmission losses, improving energy efficiency and fuel economy.
- Effectively protects against wear even with thinner oil films.
- Maintains fluidity at low temperatures for reliable winter performance.
- Safe for copper and copper alloy components.
CVT FLUIDS
MASUMA CVTF J3 HIGH VISCOSITY
A fully synthetic, high-viscosity transmission fluid for belt-driven CVTs from Toyota, Honda, and other Japanese manufacturers.
- High thermal resistance and stability under extreme operating conditions.
- Resistant to shearing and foaming for smooth and precise transmission performance.
- Maintains fluidity at low temperatures, ensuring reliable winter operation.
- Safe for copper and copper alloy components.
MASUMA CVTF J2 LOW VISCOSITY
A fully synthetic, energy-efficient, low-viscosity transmission fluid for modern belt-driven CVTs in Japanese vehicles, including JATCO CVT8/JF016E/JF017E.
- Reduces transmission losses, improving energy efficiency and fuel savings.
- Provides excellent wear protection even with thinner oil films.
- Maintains fluidity at low temperatures for consistent winter performance.
- Safe for copper and copper alloy components.
