A system and method is provided for identifying an unknown object from an object class such as transmissions, engines, and other parts. The system utilizes a classification scheme configured to distinguish objects of the object class based upon variations observable through visual inspection. In many instances, these variations can be relatively obscure. In use, the system presents sets of options for selection by a user. Each set is directed to a particular feature for distinguishing objects of the object class, and each option represents a distinct configuration for the corresponding feature. The system receives a selection of one of the options from each set of options presented that corresponds to a feature found on the unknown object. Once the system receives sufficient information in accordance with the classification scheme, it presents an identification for the unknown object. Beneficially, identification is accomplished through visual inspection of the unknown object without disassembly or need of substantial familiarity with the system or objects of the object class. In a preferred embodiment, the classification scheme directed to an object class of transmissions and is implemented in decision tree structure in which the sets of options are presented sequentially.
