Precision Shifts & Ultimate Protection: Red Line D4 ATF

Maximize the performance of your automatic transmission, manual gearbox, or power steering system with Red Line D4 ATF (Part #50604), the versatile, full synthetic fluid available at Straight Six Imports. Engineered to meet and exceed the latest OEM specifications, D4 ATF offers superior thermal stability and a consistent viscosity profile under extreme temperatures.

While designed to replace common OEM fluids like Dexron VI, Mercon LV, and Toyota WS, D4 ATF is highly popular among enthusiasts for its unique ability to upgrade other systems:

• Honda/Acura Manual Transmission Upgrade: D4 ATF is widely recognized as a premium, low-drag replacement for standard MTF in many Honda and Acura manual transmissions (e.g., K-series, B-series). Its lightweight viscosity can improve shift speed and reduce cold notchiness.

• High-Performance Power Steering: Its shear-stable formula and superior anti-wear package make it an excellent choice for power steering systems that experience high heat and pressure, improving pump lifespan and steering feel.

• Automatic Transmission Excellence: Offers excellent protection for high-mileage automatics and maintains consistency across extreme temperatures, crucial for proper shift timing and longevity.

D4 ATF's ester base stocks provide superior film strength compared to conventional fluids, reducing friction and extending the life of seals, synchronizers, and valves.

Choose Red Line D4 ATF (50604) for enhanced efficiency and robust protection across multiple systems in your performance vehicle.
