Redline BMW Transmission Filter Kits & Transmission Service Parts for MINI

Clear BMW chassis

Please ensure your correct model is selected

BMW automatic transmissions require a regular filter and fluid change. While BMW has recently implemented 'Lifetime' fluid on most current models, we feel that it is critical to change the transmission filter and flush the fluid at least every 50,000 miles. We carry the BMW transmission filters and special transmission fluids for your BMW.

Red Line 70W/80W GL-4 MTL gear oil (SAE 5W30/10W30 engine oil viscosity) designed for use in BMW manual transmissions. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. The MTL can be used as a replacement for the factory MTF or MTF-LT2 used by BMW. Add MTL to older BMWs that have become tough to shift will restore shift smoothness. Many experts agree that this is best lubricant to use in BMW manual transmissions. Sold by the quart.

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 fluids were 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.

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.

Features:

  • Provides G-4 level gear protection (suitable for transmissions and transaxles, like the Corvette T-56).
  • Provides smooth and consistent shifts.
  • More stable than petroleum fluids; suitable for extended drain intervals.
  • Does not varnish at high temperatures.
  • Improved cold weather characteristics.
