Fluid - A/T: Description and Operation
AUTOMATIC TRANSMISSION FLUID
The automatic transmission fluid is selected based upon several qualities. The fluid must provide a high level of protection for the internal components
by providing a lubricating film between adjacent metal components. The fluid must also be thermally stable so that it can maintain a consistent viscosity
through a large temperature range. If the viscosity stays constant through the temperature range of operation, transmission operation and shift feel will
remain consistent. Transmission fluid must also be a good conductor of heat. The fluid must absorb heat from the internal transmission components and
transfer that heat to the transmission case.
