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 nine positions:
Position | Definition | Character | Description |
---|---|---|---|
1 | GM Division Identifier | C,N | Chevrolet |
T,K | GMC | ||
H | Oldsmobile | ||
2 | Model Year | Y | 2000 |
3 | Assembly Plant | K | Linden, NJ |
8 | Shreveport, LA | ||
2 | Moraine, OH | ||
X | E.E.M.S | ||
4-9 | Plant Sequence Number | -- | -- |
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:
VIN Derivative Position | Equivalent VIN Position |
---|---|
1 | 3 |
2 | 10 |
3 | 11 |
4-9 | 12-17 |
