Phillips 66® VersaTrans® CVT Plus Fluid is a premium-quality, full-synthetic transmission lubricant specifically engineered for use in passenger cars and light trucks with both belt-driven and chain-driven continuously variable transmissions (CVTs). With more than 1 million miles of on-road testing, this fluid is designed to meet the unique frictional requirements of modern CVTs while also providing service-fill capability for many step-type automatic transmissions. Its advanced chemistry ensures high steel-on-steel friction to prevent belt slippage, paired with low steel-on-paper friction to eliminate torque converter shudder. This dual-purpose formulation allows for optimized inventory management while providing industry-leading protection against wear, oxidation, and sludge formation in the most demanding stop-and-go driving conditions.
