Red Line High-Temp Automatic Transmission Fluid (1 Qt)

The Red Line Synthetic High-Temp Automatic Transmission Fluid is designed to provide excellent low-temperature shiftability and improved thermal stability over petroleum ATFs. 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. The superior stability compared to petroleum ATFs also allow high-temperature operation without varnishing valves and clutches, which leads to transmission failure.

- 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.
