The Ultimate Low-Viscosity Performer: Red Line D6 ATF

Upgrade your transmission's efficiency and lifespan with Red Line D6 ATF Full Synthetic Fluid (Part #30704), the lowest viscosity, most shear-stable fluid in the Red Line lineup, available now at Straight Six Imports. Engineered to satisfy modern, fuel-efficient specifications, D6 ATF is the ideal choice for demanding automatics, modern transaxles, and select manual gearboxes.

D6 ATF provides the superior thermal stability and consistent viscosity required by specifications like Dexron VI, Mercon LV, Toyota WS, and ZF 6/8 speed fluids. Its specialized synthetic base stocks prevent high-temperature breakdown and varnishing, which are leading causes of transmission failure.

Key Performance Features for Import & Performance Vehicles:

• Lowest Viscosity Stability: Designed for better fuel efficiency (CAFE testing) while remaining incredibly shear-stable—maintaining its viscosity integrity longer than conventional synthetics.

• GL-4 Gear Protection: Uniquely provides a GL-4 level of gear protection, making it a superior, multi-purpose product often used as an upgrade in manual transmissions and transaxles requiring a thin, high-protection fluid.

• Superior Thermal Stability: Allows for high-temperature operation without varnishing valves and clutches, which ensures smooth, consistent shifts for extended drain intervals.

• OEM Compatibility: Highly recommended for use where Dexron VI, Mercon LV, Mercon SP, Honda DW-1, Toyota WS, Mercedes Benz NAG-2, or ZF Lifeguard 6/8 fluids are specified.

• Improved Cold Shifting: The low pour point and viscosity ensure quick lubrication and improved shifting performance during cold starts.

For consistent operation and uncompromising protection, choose Red Line D6 ATF (30704) for your high-performance drivetrain.
