- The extent of test conditions on the dynamometer must be sufficient to determine the efficiency characteristics corresponding to the following range of vehicle operations in all gear ratios with locked torque converters (open converter can also be done where appropriate and noted).
-
a
Efficiency versus output speed versus input torque
-
b
Torque ratio versus output speed
-
c
Input speed versus output speed
-
d
Output torque versus output speed
-
e
Parasitic loss versus input speed (spin losses)
-
f

-
g
Output torque bias (front wheel drive transaxles)
