Automatic transmission fluid. 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.
This transmission utilizes bronze synchronizer collars resulting in sensitivity to lubricant make-up. Only a fluid characterized by Chrysler specification MS-9224 should be used in order to avoid premature wear or failure of internal parts as well as voiding the factory warranty. [2] Pennzoil Synchromesh is one such petroleum based lubricant. [3]
Salen is a typical metal-deactivator. Metal deactivators, or metal deactivating agents (MDA) are fuel additives and oil additives used to stabilize fluids by deactivating (usually by sequestering) metal ions, mostly introduced by the action of naturally occurring acids in the fuel and acids generated in lubricants by oxidative processes with the metallic parts of the systems.
This was the world's first automatic transmission fluid, designed for the world's first mass-produced automatic transmission. [2] This fluid had cold-weather performance problems, which led to the need for an improved fluid, the Type "A" fluid, in 1949. The Hydra-Matic drive fluid was only available at GM dealerships.
In 1959, Ford released their own Type-A automatic transmission fluid specification (M2C33-A) and stopped using GM fluid specifications for their in-house transmissions. The Ford M2C33-A fluid had GM Type "A" Suffix "A" characteristics. Transmission fluid service life was fairly short, and frequent transmission oil changes were required.
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]
Methylenebis(dibutyldithiocarbamate) is an additive in some extreme pressure gear oils, serving as an antioxidant and protecting metal surfaces. [1] The early extreme pressure additives were based on lead salts of fatty acids ("lead soaps"), "active sulfur" compounds (e.g. thiols and elementary sulfur), and chlorinated compounds.
Thus, a warning light on the instrument panel illuminates, indicating the presence of metal chips. [1] Chip detectors may be positioned in the application with a self-closing valve/adapter through either a bayonet or threaded interface. As the chip detector is disengaged from the valve, the valve closes minimizing any fluid loss from the system.
