Since the torque converter and fluid coupling are commonly used components of automatic transmissions in industry, the SAE appointed a committee to standardize terminology, test procedure, data recording, design symbols, and so forth, in this field. The following committee recommendations will facilitate a clear understanding for engineering discussions, comparisons, and the preparation of technical papers. The recommended usages represent the predominant practice or the acceptable practice. Where agreement is not complete, alternates have been included for clarification. EXAMPLE: Two systems of blade angle designations are described. Consequently, when a blade angle is specified, the system should be designated. This SAE Recommended Practice deals only with the physical parts and dimensions and does not attempt to standardize the design considerations, such as the actual fluid flow angle resulting from the physical blade shape.

To provide a means of obtaining the efficiency characteristics of automatic transmissions and automatic transaxles. It outlines dynamometer tests that map the steady-state characteristics over a range of operations of an automatic transmission/automatic transaxle and provides a method of presenting test data. This procedure must be followed, with similar test facilities so that results obtained from different laboratories are comparable. For this SAE Recommended Practice, the transmission is defined as the complete automatic transmission or transaxle assembly between the engine and the driveshaft(s) used to effect a ratio change in transmitting power. For 4WD/AWD, it does not include transfer case or power take off subsystems. This test procedure deals with the aspect of conducting complete transmission and transaxle assembly testing.

For this SAE Recommended Practice, the transmission is defined as the complete automatic transmission or transaxle assembly between the engine and the driveshaft(s) used to effect a ratio change in transmitting power. This test procedure deals with the aspect of conducting complete transmission and transaxle assembly testing. However, by its very nature a transmission should be viewed as a compilation of three major component systems: pump, torque converter, and gearbox (all ratio change elements).
The range of test conditions on the dynamometer shall be sufficient to determine the primary operating characteristics corresponding to the full range of vehicle operations. The transmission characteristics to be determined for all driving ranges or gears are: 1 Efficiency versus output speed. 2 Torque ratio versus output speed. 3 Input speed versus output speed. 4 Output torque versus output speed. 5 Parasitic losses versus input speed.
To provide a means of comparing the performance characteristics of automatic transmissions. It outlines dynamometer tests that cover the range of operation of transmissions and provides a method of presenting the test data. This procedure must be followed with similar test facilities so that results obtained from different laboratories are comparable. For this SAE Recommended Practice, the transmission is defined as the complete assembly driven by the engine and used to effect a ratio change in transmitting power to the final drive system.
