Red Line D4 ATF is a popular choice for owners of BMWs with automatic transmissions as well as manual transmissions from 1993 onward. D4 ATF also provides a GL-4 level of gear protection, giving it balanced frictional characteristics that 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 ATF also provides improved shifting in cold weather.
- Versatile ATF provides a GL-4 level of gear protection
- Appropriate coefficient of friction for most manual transmission synchronizers
- Excellent for high- and low-mile transmissions
- Excellent cold weather operation
