FACT: Due to the differences in the chemical properties of aluminum and iron, most of the boundary lubricants designed for ferrous materials fail to form protective films on aluminum. ATF and hydraulic fluid are simply not formulated to protect aluminum. Even high-strength grade aluminum such as 6061 can wear rapidly when in contact with harder steel surfaces. SOLUTION: LUBEGARD Aluminum Protectant is the only additive specifically formulated to protect aluminum and aluminum Alloys such as valve bodies, servo bores and pistons when in contact with steel and/or other aluminum. When added to automatic transmissions, LUBEGARD Aluminum Protectant reduces wear on aluminum by an average of 35%, providing longer component and transmission life. Add 1 ounce of LUBEGARD to one quart of ATF for a total capacity of transmission. Do not exceed the 1-oz-per-quart treat rate. It can also be used in conjunction with one of the LUBEGARD ATF Protectants.
