Red Line D4 ATF is a fully-synthetic automatic transmission fluid designed to deliver superior performance across a wide range of vehicles and applications. This case contains twelve 1-quart bottles, providing excellent value for shops, enthusiasts, or multiple vehicle maintenance.

Versatile Compatibility:

Red Line D4 ATF is the most versatile synthetic ATF available, suitable for use where Dexron III, Dexron II, Mercon, and Mercon V fluids are specified. Popular applications include Toyota Type T-III and T-IV, Honda ATF-Z1, Nissan Matic D/J/K/S, Diamond SP-II and SP-III, Mazda ATF M-V, and most BMW, Audi, and VW automatic transmissions. D4 ATF also provides GL-4 level gear protection, making it ideal for use in manual transmissions and transaxles like the T-5, T-45, T-56, and late-model BMW gearboxes.

Performance Benefits:

• Superior low-temperature fluidity provides improved cold-weather shifting and faster oil circulation on startup
• Enhanced thermal stability prevents breakdown and varnishing of valves and clutches at high operating temperatures
• Balanced friction characteristics deliver smooth, consistent shifts throughout extended drain intervals
• Fully-synthetic formulation reduces oxidation and volatility compared to petroleum-based ATF
• Excellent shear stability maintains optimal viscosity under stress
• Appropriate friction coefficient for proper synchronizer engagement in manual transmissions

Whether you're servicing automatic transmissions, manual gearboxes, transaxles, or power steering systems, Red Line D4 ATF provides professional-grade protection and performance. The advanced synthetic formula extends component life, improves shift quality, and maintains consistent operation across a wide temperature range.
