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 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).

Automatic Transmission Intake Filter Test Procedure

2005-04-26
HISTORICAL
J2312_200504
This test procedure is intended to apply to hydraulic pump suction filters and strainers used in automotive automatic transmissions that include hydraulic power pumps. The various paragraphs of Section 5, "Test Procedures," include a variety of tests and alternative tests that are not applicable to all filters and applications, so the engineer must specify which tests are to be performed for a particular application. These test procedures are intended to evaluate filter functional performance characteristics only, durability is not evaluated under this standard. Filter design requirements must be specified by the engineer on the filter assembly drawing, an applicable engineering specification, or they may be summarized on an application data sheet similar to that found in this recommended practice. See Figure 6, "Filter Assembly Application and Data Sheet." Pressure circuit filters, both barrier and system contamination control types, are not covered under this standard.

Hydrodynamic Drives Terminology

2000-03-10
HISTORICAL
J641_200003
Since the torque converter and fluid coupling have become 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.

Glossary of Terms-Lubricated Friction Systems

1996-07-01
HISTORICAL
J1646_199607
This SAE Recommended Practice defines the principal terms and equations pertaining to automotive automatic transmission clutch plate, band, or other wet-friction systems. The terms apply directly to friction-system testing as is typically conducted on inertia-stop test equipment. Some terms can be directly applied to the analysis of friction in the transmission or brake assembly and other friction-test equipment. The glossary presents terms used to describe the set-up, testing, and results of tests as shown in Figure 1, which were taken on a clutch SAE No. 2 machine. The glossary is intended to provide a collection of definitions in the hope of eliminating confusion in terminology and a common set of terms for improving the state-of-the-art of friction-system development and their application to passenger cars and trucks. This document focuses on the terminology of friction-system testing. Reference for this type of testing are shown in Section 2.
