Red Line D4 ATF Gear Oil

Red Line D4 ATF (Automatic Transmission Fluid)

Red Line’s most versatile Automatic Transmission Fluid, use where Dexron III®, Dexron II®, Mercon® and Mercon V® fluids are recommended, for use in automatic, manual transmissions and power steering

D4 ATF is a fully-synthetic product designed with superior low-temperature properties compared to a Dexron III® fluid, and the improved shear-stability requirements which is part of the Mercon V® specifications.

D4 ATF also provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum ATFs allows high-temperature operation without varnishing valves and clutches which leads to transmission failure.

Red Line D4 ATF is also suitable for use in some power steering systems including the BMW E36 / E46 and the Nissan 350Z

Red Line ATFs are designed for the perfect shiftability.

With the most stable base oils to provide improved durability. Conventional ATFs lose viscosity through the shearing action in the transmission and evaporate at high temperatures. Red Line ATFs are shear-stable and very resistant to evaporation even at extreme temperatures.
