All engines and transmissions are stamped with a partial Vehicle Identification Number (VIN), which is derived from the complete VIN. A VIN derivative contains the following nine positions:
| • | Position 1 is the GM division identifier: |
| 6 = Cadillac |
| • | Position 2 is the model year: |
| X = 1999 |
| • | Position 3 is the assembly plant code: |
| U = Hamtramck MI. |
| • | Positions 4-9 contain the assembly plant sequential number for the vehicle. |
| 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 1 = VIN position 3 |
| • | VIN derivative position 2 = VIN position 10 |
| • | VIN derivative position 3 = VIN position 11 |
| • | VIN derivative positions 4-9 = VIN positions 12-17 |
