## Transmission ID and VIN Derivative Location Corvette T56 and 4L60E

All engines and transmissions, as well as removable roof panels 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 1 is the GM division identifier.

| 1 = Chevrolet

• | Position 2 is the model year code.

| Y = 2000

• | Position 3 is the assembly plant code.

| 5 = Bowling Green, KY

• | 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, transmission or removable roof panel, 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

### Borg Warner T-56 Manual Transmission

The 6-speed manual transmission, the Borg Warner T-56 (RPO MM6), is stamped with a VIN derivative on the LH side of the transmission case.

### Hydra-Matic 4L60-E Automatic Transmission
