Passenger Car and Light Truck Automatic Transmission and Automatic Transaxle Test Code (Stabilized: Jun 2015)

Summary

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).
  1. a
    Efficiency versus output speed versus input torque
  2. b
    Torque ratio versus output speed
  3. c
    Input speed versus output speed
  4. d
    Output torque versus output speed
  5. e
    Parasitic loss versus input speed (spin losses)
  6. f
    Cooler flow
  7. g
    Output torque bias (front wheel drive transaxles)
