This SAE Recommended Practice was prepared by the SAE Fuels and Lubricants Technical Committee: (a) to assist the designers and users of heavy-duty transmissions in the selection of powershift transmission fluids for field use and (b) to promote a uniform practice for use by marketers of lubricants and equipment builders in identifying and recommending these fluids by type. This classification is designed for fluids used in heavy-duty truck, bus, earthmoving, and marine transmissions or steering clutches. The fluids must perform the following five functions: 1. Transmit hydrodynamic energy in a torque converter. 2. Transmit hydrostatic energy in hydraulic circuits. 3. Lubricate bearings, bushings, gears, and moving parts. 4. Provide proper frictional properties in lubricated bands and clutches. 5. Provide heat transfer medium for liquid- or air-cooled systems to maintain suitable operational temperature range.
This SAE Information Report was prepared by the SAE Fuels and Lubricants Technical Committee for two purposes: (a) to assist the users of automotive equipment in the selection of axle1 and manual transmission lubricants for field use, and (b) to promote a uniform practice for use by marketers of lubricants and by equipment builders in identifying and recommending these lubricants by a service designation.

Table 1 lists the components of construction and industrial equipment and the various lubricants which may be used. Table 2 lists lubricant types and identifying abbreviations. Lubricants that had common usage in the past are retained in Table 2 to show where the new specifications originated. Original factory lubrication may deviate from field recommendations because of special requirements, such as breakin. Lubricant viscosity grade should be selected for various climatic conditions (described in SAE J300 and SAE J307). The final selection of the lubricant and grade will depend upon the requirements of the equipment manufacturer.
