Scope
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 characteristics to be determined are:
-
a
Torque ratio versus speed ratio and output speed
-
b
Input speed versus speed ratio and output speed
-
c
Efficiency versus speed ratio and output speed
-
d
Capacity factor versus speed ratio and output speed
-
e
Input torque versus input speed
NOTE: For more information about these characteristics and the design of hydrodynamic drives, refer to “Design Practices: Passenger Car Automatic Transmissions,” SAE Advances in Engineering, AE-18 (Third Ed.) or AE-29 (Fourth Ed.).
Rationale
This document is being revised to provide improved clarification.

Issuing Committee
Automatic Transmission and Transaxle Committee
The Automatic Transmission and Transaxle Standards Committee reports to the Powertrain Systems Group of the Motor Vehicle Council. The Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to all systems, subsystems, and components of automatic transmissions, including both step ration and CVT designs. This committee will direct its attention to passenger cars and light trucks. Participants in the SAE Automatic Transmission Transaxle Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
