The original DEXRON (B) fluid, as well as earlier GM transmission fluids, used sperm whale oil as an additive to coat internal transmission parts to prevent corrosion and rust. The U.S. Endangered Species Act banned the import of sperm whale oil, so the DEXRON (B) fluid additive package had to be reformulated. [ 13 ]
Automatic transmission fluid (ATF) is a hydraulic fluid that is essential for the proper functioning of vehicles equipped with automatic transmissions. Usually, it is coloured red or green to differentiate it from motor oil and other fluids in the vehicle.
Half of the discs are connected to the inner, the other half to the outer, alternating inner/outer in the stack. Differential motion forces the interleaved discs to move through the fluid against each other. In some viscous couplings when speed is maintained the fluid will accumulate heat due to friction.
There is no sales pitch, this information is universally true and applies to all manufacturers of automatic transmission fluids. Transmission fluid is a combination of a group 1-5 base oil (including synthetically produced base oils) and an additive package. Some additive packages are much better than others.
Some modern automatic transaxles (integrated transmission and differential) do not use a heavy oil at all but lubricate with the lower viscosity hydraulic fluid, which is available at pressure within the automatic transmission. Gear oils account for about 20% of the lubricant market. [1]
Organo-molybdenum compounds, were initially developed as antiwear additives but were later recognized to be very effective in reducing boundary friction. [3] They are currently used in many engine oils and, more recently, in gear oils. [1] They reduce friction by forming two-dimensional molybdenum disulphide layers on rubbing surfaces. [4]
