LUBEGARD ATF PROTECTANT is a concentrated additive package infused with superior seal conditioners and friction modifiers. This unique product restores additive content to used ATFs and enhances new ATFs 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 Ford Type F ATF, CVT or DCT. 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 pyrolyze, 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 Deg 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.
