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.

The oil in your manual transmission is extremely vital to the life of your transmission. Over time it will begin to break down, lose viscosity, and begin to allow excess heat and friction. This kit is the perfect remedy to this problem. Included are 2 Liters of Redline D4 ATF, which is recommended by Redline for this manual transmission and features a fully synthetic base for better protection and wear resistance, a URO fill plug, and an ECS Magnetic Drain Plug.
