SAE 930907 deals with the parasitic losses and efficiencies attributed to the automatic transmission and its individual components:

  • Pump

  • Torque converter

  • Gearbox

The discussion is limited to the nominal speed/torque operating range encountered on the EPA city-highway driving schedule.
