Automatic Transmission Fluid Protectant with LXE® Technology


LUBEGARD® Synthetic Automatic Transmission Fluid Protectant is a concentrated additive package infused with superior seal conditioners and friction modifiers. This unique product restores additive content to used ATF and enhances new ATF resulting in improved performance and smoother, more consistent shifting. It can safely be added to any automatic transmission fluid (ATF) including full synthetic, semi synthetic, conventional, and low viscosity fluids except CVT, DCT, and Ford Type F [1986 and earlier models] LUBEGARD® Synthetic Automatic Transmission Fluid Protectant is engineered to raise the thermal and oxidative stability level of automatic transmission fluids, so when it operates at elevated temperatures, it does not thin out and pyrolize, burn, or react with oxygen and form deposits. It is formulated with proprietary Liquid Wax Esters (LXE®) that are unique because of their natural lubricity, high viscosity index, and high flash and fire points. They have the ability to withstand repeated heating to temperatures as high as 570°F. LXE® gives automatic transmission fluid the extra lubricity needed for transmission’s unique frictional requirements. They improve heat conductivity, suppress foaming and, consequently, reduce transmission operating temperatures. LXE also improves cold temperature performance by reducing the fluid's pour point, preventing the fluid from thickening in frigid temperatures.

Features & Benefits

  • For use with any required *ATF’s! Check out our OEM ATF & Conversion Chart for coverage.

  • Protects new seals and permanently restores older seals to a “like-new” condition, without adverse side effects.
  • Also for use in manuals that require ATF

*Except CVT, DCT, and Ford Type F [1986 and earlier models] applications.

directions for use

LUBEGARD® Synthetic Automatic Transmission Fluid Protectant can be added to any ATF (except CVT, DCT, and Ford Type F [1986 and earlier models] fluid.) For normal applications, add 1 oz. (29.6 mL) of Lubegard per 1 qt. (L) of ATF for the total capacity of the transmission. Always consult your owners manual for vehicle specific instructions. To determine fill capacity, use our OEM ATF & Conversion Chart
