Redline Automatic D4 ATF

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. - Use where Dexron III®, Dexron II®, Mercon® and Mercon V® fluids are recommended, provides a GL-4 level of gear protection. - Also used with manual transmissions and transaxles like T-5, T-45, T-56 and late-model BMW - Excellent cold weather operation.
