Lucas Oil Sure-Shift Semi-Synthetic Automatic Transmission Fluid

Lucas Oil Sure-Shift Semi-Synthetic Automatic Transmission Fluid is a premium ATF engineered with a carefully balanced blend of high-quality mineral base stocks and synthetic components, supported by a specialized additive package designed to go well beyond what conventional automatic transmission fluids deliver. Trusted by ET racers, daily drivers, and fleet operators alike, Sure-Shift ATF reflects Lucas Oil's long-standing commitment to lubrication solutions that exceed OEM expectations and deliver real-world protection where it matters most.

Key Features:

• Semi-Synthetic Formula: Combines quality mineral base stocks with synthetic components for superior thermal and oxidative stability over conventional ATF, along with improved cold-temperature flow characteristics
• Smooth, Precise Shifting: Formulated with lubricity agents developed to deliver crisp, consistent shifts demanded by performance and racing applications, while remaining equally well-suited for everyday street use
• High-Temperature & High-Pressure Resistance: Engineered to maintain viscosity and performance under the elevated temperatures and pressures generated during towing, hauling, and performance driving — without thinning or foaming
• Advanced Anti-Wear Protection: Special additive package includes extra detergents and anti-wear agents not commonly found in standard ATF formulations, helping reduce internal component wear and extend transmission service life
• Foam Resistance: Resists aeration and foaming to maintain consistent hydraulic pressure across all operating conditions
• Extended Fluid & Transmission Life: Helps reduce fluid degradation and prolongs overall transmission life in both passenger car and truck applications
• Broad Specification Compatibility: Meets or exceeds Dexron III / Mercon / Mercon V / Allison C-4 performance standards, making it suitable for a wide range of domestic automatic transmissions
• No-Flush Switchover: Can be added directly to transmissions already running a compatible fluid — no system flush required when the existing fluid meets the same specifications

Important Notes:

• Not recommended for use in continuously variable transmissions (CVT)
• Not recommended for transmissions requiring Ford Type F fluid
