High-Temp ATF: Perfect for heavily-loaded vehicles like motor homes and towing applications due to its higher viscosity than our D4 ATF. This is a synthetic ATF for use where Dexron III or Mercon is recommended.
This product provides the gear protection of a GL-4 gear oil in an ATF and provides a higher viscosity at higher operating temperatures, allowing the transmission to operate at 70°F higher temperature and still provide the optimal shiftability and improved torque converter efficiency.
