To understand how a fluid can last a "lifetime", a study of the 1939 Chrysler Fluid Drive Fluid is helpful. The lesson learned by Chrysler with its fluid drives is applicable to modern automatic transmissions as well. The November 1954 edition of Lubrication Magazine (Published by The Texas Company, later known as Texaco) featured a story called ""Evolution of the Chrysler PowerFlite Automatic Transmission"." This article described the fluid used in the 1939 Chrysler Fluid Drive and its subsequent revisions and enhancements through 1954.
