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

The 4-speed overdrive automatic transmission, the Hydra-Matic 4L60-E (RPO M30), is stamped or laser etched with a transmission identification number and a VIN derivative.

Transmission Identification

The transmission identification number provides the transmission model and when it was built. The transmission (ID) number is located on the bottom of the case just rear of the oil pan.

The HYDRA-MATIC 4T40-E transmission has a metal identification nameplate (1) attached to the case exterior.

The information on the nameplate assists the technician in servicing the transmission and ordering replacement parts from a GM Parts Catalog.

Additional transmission identification information is provided on the Service Parts Identification label. This label shows the Regular Production Options (RPO) as well as the standard and mandatory options. This label is affixed to the inside of each vehicle at the assembly plant. Refer to General Information for label location and additional information.
