Abstract
A differential score protection system that regulates an engine to inhibit damage to a differential driven by the engine includes a first module that initiates a differential score protection mode and a second module that decreases an engine speed when the engine speed exceeds an engine speed limit. The engine speed limit is one of a plurality of pre-determined values based on a design slip speed limit of the differential.
