All engines and transmissions are stamped or laser etched with a partial Vehicle Identification Number (VIN), which was derived from the complete VIN. A VIN derivative contains the following 9 positions:
Position | Definition | Character | Description |
---|---|---|---|
1 | GM Division Identifier | C H K N T | Chevrolet Truck Oldsmobile MPV GMC MPV Chevrolet MPV GMC Truck |

3 | Assembly Plant | K 8 2 X | Linden, NJ Shreveport, LA Moraine, OH E.E.M.S |

A VIN derivative can be used to determine if a vehicle contains the original engine or transmission, by matching the VIN derivative positions to their accompanying positions in the complete VIN:
