Synthetic D4 ATF is suitable for use where Dexron III, Dexron II, or Mercon fluids are recommended. ATF 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. The D4 ATF provides significantly improved gear protection than most OEM oils. 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.

This is Red Line's latest synthetic transmission fluid that is compatible with BMW's MTF-LT3 transmission fluid. This is the transmission fluid used in both manual and automatic transmissions since the mid-2000's. To confirm, check the decal located on the side of your transmission. Price is per quart.
Synthetic D6 ATF is a lower viscosity version of the D4ATF and is designed for better fuel efficiency in CAFE testing. Dexron VI requires a different approach to a conventional ATF formulation. Rather than beginning with a 7.5 cSt fluid and allowing a viscosity loss in use to drop to 5.5 cSt, the Dexron VI fluid requires a starting viscosity of less than 6.4 and a final drop to no less than 5.5 cSt. Red Line D6 will drop to no less than 6.1 cSt. Since the final viscosity after use of these fluids are similar, Dexron VI fluids can be used where Dexron III fluidswere previously recommended (with the exception of some manual transmission applications, our customers report).
D6 ATF also provides significantly improved gear protection and will provide a GL-4 level of gear protection. 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.
CVT (Multitronic) Automatic Transmission Fluid - 1 Quart is essential for maintaining the performance and longevity of your Mini's transmission. Regular replacement of your transmission fluid can prevent premature wear and potential damage to your gearbox. Adhering to the manufacturer's recommended service interval is crucial to ensure optimal performance.
