A method of improving performance of secondary driveline clutches in motor vehicle transfer cases includes the steps of testing each manufactured transfer case to determine the clutch drive current versus torque transfer function, fitting such determined function to one of a small number of predetermined performance curves and incorporating an identification of the selected one of such predetermined performance curves in the transfer case. When the transfer case is installed in a vehicle, the curve identification is read and the transfer case control module (TCCM) adjusts its clutch drive signal in accordance with the predetermined curve to achieve known and desired torque transfer through the clutch with a given clutch drive signal.
