Engine and Transmission Identification Numbers
This SAE Recommended Practice has been established to provide direction for the design and installation of an identification number as assigned to passenger car and truck engines and transmissions. In adhering to these recommended practices, facility of application in factory production and appearance are matters for manufacturer control. Reference SAE J853.
Rationale: The standard needs to be revised to reflect current government regulations on engine and transmission marking. Items to be added include traceability back to vehicle VIN, permanency, and height requirements.
