Idemitsu CVT Transmission Fluid SB2 1-Quart — CVTF II Synthetic Blend for Smooth Shifts and Anti-Wear

Idemitsu CVT Transmission Fluid Type SB2 is a 1‑quart CVTF II formula designed to lubricate, protect, and optimize continuously variable transmissions, including compatibility with Subaru TR580 units.

This synthetic blend is engineered for modern continuously variable transmissions (CVTs) and formulated to control friction, resist deposits, and withstand heat and shear. Supplied in a convenient 1‑quart (946 mL) bottle, the Idemitsu SB2 CVT fluid is intended for topping off or small service jobs where the manufacturer's Type CVTF‑II specification is required. It offers anti‑wear additives and viscosity characteristics tuned for smooth belt and pulley operation in compatible vehicles.

How does this fluid affect shifting feel and drivability?

The SB2 CVT formula manages friction precisely so pulleys and belts transition more smoothly, reducing the likelihood of hard or jerky gear changes. By maintaining consistent hydraulic pressure and frictional behavior, it helps preserve predictable throttle response and steady acceleration under varying loads.

• Friction modifiers tailored for CVT belt and pulley interaction
• Viscosity stability to prevent shift harshness under temperature changes
• Hydraulic properties that support consistent transmission control

Will this fluid protect my transmission components over time?

Idemitsu SB2 contains anti‑wear additives and deposit inhibitors intended to minimize wear on belts, pulleys, and gears while resisting sludge and varnish formation. While no fluid can eliminate all wear, this CVTF II formulation is optimized to prolong component life when used according to vehicle manufacturer guidance.

• Anti‑wear chemistry to reduce metal and belt deterioration
• Deposit control to keep valve bodies and passageways cleaner
• Thermal and shear resistance for longer service stability

Is this fluid compatible with my vehicle and how much do I get?

This product meets Type CVTF‑II specifications and is compatible with transmissions that list SB2 or CVTF‑II standards, including Subaru TR580 applications when specified by the manufacturer. The package contains one 1‑quart (946 mL) bottle, suitable for top‑offs or partial fills; always check your owner’s manual for exact capacity and compatibility before use.

• Meets CVTF‑II performance requirements
• Listed as suitable for Subaru TR580 where applicable
• Single 1‑quart bottle for easy topping off or small fluid changes

How should I use and store the Idemitsu SB2 CVT fluid?

Use this fluid only in transmissions that specify CVTF‑II or SB2 compatibility. Pour during a cool, level servicing environment; follow vehicle service procedures for accurate fill levels and bleeding. Store the sealed bottle in a dry, temperature‑controlled space away from direct sunlight and extreme temperatures.

• Follow your vehicle manufacturer's fill and service instructions
• Keep bottle upright and sealed when not in use
• Dispose of used fluid according to local regulations

Who is this for: Vehicle owners, independent mechanics, and fleet technicians who need a CVT fluid meeting Type CVTF‑II specifications for topping off or small jobs. It’s a convenient 1‑quart option for those working on compatible transmissions—particularly models referencing Subaru TR580—who want a purpose‑built fluid to support smooth CVT operation and component longevity.
