SAE No. 2 Clutch Friction Test Machine Guidelines
2012-03-19
CURRENT
J286_201203
This SAE Recommended Practice is intended as a guide toward implementation of a standard practice but may be subject to frequent change to keep pace with experience and technical advances. This should be kept in mind when considering its use. The SAE No. 2 Friction Test Machine is used to evaluate the friction characteristics of automatic transmission plate clutch with automotive transmission fluids. It can also be used to conduct durability tests on wet friction systems. This document is intended for common use by both suppliers and end users to define minimum test machine requirements to allow objective comparisons of wet friction material system performance.

Passenger Car and Light Truck Automatic Transmission and Automatic Transaxle Test Code
2005-06-22
HISTORICAL
J651_200506
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.

J651C_197906
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.

To provide a means of obtaining the performance 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. 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).
