Idemitsu CVT Transmission Fluid SB2 for Subaru TR580 — 1 Qt, CVTF‑II Anti‑Wear & Smooth Shift

This specialized CVT fluid from Idemitsu is blended to provide controlled friction, thermal stability, and anti-wear protection for vehicles that require SB2 / CVTF-II specification oils. Packaged in a convenient 1-quart (946 mL) bottle, it’s designed for topping off or changing the fluid in compatible Subaru TR580 transmissions to maintain smoother gear operation and reduce wear on belts and pulleys.

How does Idemitsu CVT Type SB2 improve shifting performance?

The fluid’s frictional characteristics are engineered to promote consistent clutch engagement and prevent hard or jerky shifts commonly experienced with poorly matched oils. Its formulation supports the precise torque transfer behavior CVT systems need for smooth, linear acceleration.

• Friction modifiers tuned for CVT clutch control and smooth engagement
• Viscosity tailored to maintain performance across a range of temperatures
• Anti-jerk properties to reduce drive-train shock during gear transitions

Will this bottle protect my transmission against wear and deposits?

Idemitsu SB2 includes anti-wear additives and detergents that minimize metal-on-metal contact and resist deposit formation. That helps preserve belt, pulley, and gear life while keeping hydraulic circuits clean for reliable pressure control.

• Anti-wear chemistry reduces surface degradation on moving parts
• Deposit-resistant base and additive package maintain fluid flow and valve operation
• Stable properties under heat prevent viscosity breakdown during heavy use

Is this the right fluid for my Subaru TR580-equipped vehicle?

The Idemitsu CVT Type SB2 is formulated to meet Type CVTF-II requirements and is suitable for Subaru TR580 transmissions when that specification is listed in your owner’s manual. Always confirm your vehicle’s recommended fluid spec before adding or replacing transmission oil.

• Meets CVTF-II performance criteria—compatible with many Subaru TR580 applications
• Packaged in a single 1-quart bottle for topping off or smaller service jobs
• Follow manufacturer guidance for change intervals and capacity amounts

How should I use and store this CVT transmission fluid?

Use the 946 mL bottle to top off the transmission fluid to the proper level as specified by the vehicle maker, or combine bottles when performing a full service. Store the product sealed in a cool, dry place away from direct sunlight to preserve additive effectiveness.

• Top off or refill according to the vehicle’s fill and bleed procedure
• Keep container tightly closed to prevent contamination and moisture ingress
• Dispose of used fluid responsibly per local regulations

Who is this for: Idemitsu CVT Type SB2 is aimed at Subaru owners and independent mechanics who need a CVTF-II compatible transmission oil in a convenient 1-quart size. It’s ideal for routine top-offs, partial drain-and-refill services, or for drivers who want a market-grade CVT fluid specifically matched to Subaru TR580 systems. Always verify your vehicle’s required specification before purchasing to ensure compatibility and optimal performance.
