D4 ATF is a full-synthetic product designed with superior low-temperature properties compared to a Dexron III® fluid, and the improved shear-stability requirements which are part of the Mercon V® specifications. Synthetic D4 ATF is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. D4 ATF also provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles. The balanced frictional characteristics provide 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. D4 is similar to Red Line's MTL formula and can be used in many BMW manual transmissions where MTF or MTF-LT2 is called for. Meets or exceeds the following BMW & MINI specifications: 83 22 9 407 807 (LT 71141) 83 22 0 024 359 (ETL-8072B) 83 22 0 026 922 (ETL-7045E) Dexron® III ESSO LT71141 MTF-LT-1 MTF-LT-2 Toyota Type-IV
