PASSENGER CAR VEHICLE IDENTIFICATION NUMBER

The vehicle identification number is visible through the windshield near the left door. On all passenger cars, except Corvette, it is stamped on a plate located on the instrument panel. On Corvettes, it is on the left windshield pillar.

LIGHT DUTY (10-30) TRUCK VEHICLE IDENTIFICATION NUMBER

C, K, G, S and El Camino trucks display the VIN plate on the left hand side of the instrument panel area. On P 42 models, the plate is attached to the top of the radiator support, and on Motor Home Chassis P 32, to the dash and toe panel.

MEDIUM DUTY TRUCK VEHICLE IDENTIFICATION NUMBER

On Conventional Cabs, the VIN plate is mounted on the left door lock pillar. On School Bus Chassis, the plate is attached to the engine side of the cowl. On P Models, it is located on top of the radiator support panel.

BODY IDENTIFICATION PLATE

On the Chevrolet, Malibu Classic, El Camino and Monte Carlo the body identification plate is located on the upper horizontal surface of the cowl plenum chamber. The Cavalier, Celebrity, Camaro, Citation and Chevette plate is located on the upper horizontal surface of the radiator support.

CORVETTE BODY PAINT AND TRIM PLATE

The body paint and trim plate which is stamped with the trim, paint and time built codes is attached to the left door hinge pillar.

The time built code contains an alpha representing the month followed by two numerics representing the day of the month. A is used for the first month, B for the second, etc. Example: A21 (August 21st); B02 (September 2).

LIGHT DUTY TRUCK SERVICE PARTS IDENTIFICATION STICKER

A Service Parts Identification Sticker is furnished for L.D. Trucks except El Camino. It contains a complete listing of the vehicle identification number (V. I. N.) wheel base and all production options used to assemble the vehicle, such as suspension, body equipment, engine, axle, transmission, tires, etc.

On C, K and S models, this sticker is attached to the inner glove compartment. For P models, it is mailed separately to the dealer. On G models, the sticker is located on the inner hood panel surface. 1982 PASSENGER ENGINE CODES ----------------------

The transmission codes are located as follows:

Three-Speed

The code is stamped on the left side of the case just below the side cover.

Four-Speed

The Muncie (cast iron case) transmission (Saginaw type) is stamped on the machined surface of the left side of the case just below the side cover.

The Muncie 70MM (aluminum case) transmission is stamped on the bottom center front of case.

BUILD DATE

The build date code starts with the Julian date (day of the year) on which 1982 production started. The build date code continues with the Julian date until December 31, (365).

Turbo Hydra-Matic 250C and 350C Automatic Transmissions

THM 250C transmissions produced by Chevrolet Parma and THM 350C trans- mission produced by Buick Motor Division have the production code stamped on the governor cover.

The THM 350C automatic transmissions produced by Chevrolet Toledo have a production code stamped on the right side of the oil pan. The code consists of the source, model year, month, day and shift produced.

The 700R4 transmission produced by Chevrolet Toledo has a production code stamped on the right side of the pan rail. This code differs from their 350C in that the source code has been eliminated and the model year 1982 is signified with a 9.

EXAMPLE: 9 TA 222 D - -- --- - Model Year 1982 Vehicle Application Build Date Shift D = 1st N = 2nd

PASSENGER CAR TRANSMISSION IDENT. NUMBER FOR "SERVICE" USAGE

The following system will be used to identify service transmission assemblies. This number system applies to domestically produced complete service transmission assemblies only. Transmission cases are no longer identified. Manufacturing Plants will number each service assembly as it is produced. The first letter will designate the GM Division which produced the unit - "C" (Chevrolet). The second letter will indicate the type of unit "T" (transmission). The number following the letter will designate the model year - 11211 (1982). The last five digits specify the service replacement sequence number. The group of numbers to be used by Chevrolet Manufacturing plants are as follows:

PLANT SERIAL SEQUENCE ----- --------------- Chevrolet - Parma Transmission Plant 00001 to 14999

Chevrolet - Toledo Transmission Plant 15000 to 24999

Chevrolet - Muncie Transmission Plant 25000 to 44999

EXAMPLE: Number CT200175 designates Chevrolet Transmission, year, and 175th unit produced for service at Parma.

Upon completion of the serial sequence, the plant will reuse the above numbers using a letter prefix, such as A, B, or C.

EXAMPLE: CT2A00175

Hydra-Matic Division 00001 to 99999

Hydra-Matic Division Transmissions will be numbered with the letter "H" regardless of the GM Division using the transmission.

Buick Motor Division 00001 to 99999

Buick Motor Division produced transmissions will be numbered with the letter "B" regardless of the GM Division using the transmission.

Refer to the passenger section of this bulletin for production code explanations.

TRUCK TRANSMISSION IDENTIFICATION NUMBER FOR "SERVICE" USAGE

The following system will be used to identify service transmission assemblies domestically produced. This number system applies to complete service transmission assemblies only. Transmission cases are no longer identified. Manufacturing Plants will number each service assembly as it is produced. The first letter will designate the GM Division which produced the unit - "C" (Chevrolet).

The second letter will indicate the type of unit - "T" (Transmission). The number following the letter will designate the model year - "2" (1982). The last five digits specify the service replacement sequence number. The group of numbers to be used by Chevrolet Manufacturing plants are as follows:

PLANT SERIAL SEQUENCE* ----- ---------------- Tremec Ind. - Division of Clark Equipment 0001 to 9999

Chevrolet - Parma Transmission Plant 00001 to 14999

Chevrolet -Toledo Transmission Plant 15000 to 24999

Chevrolet -Muncie Transmission Plant 25000 to 44999

Hydra-Matic 400 00001 to 99999

Hydra-Matic transmissions will be numbered with the letter "H" regardless of the GM Division using the transmission.

EXAMPLE: Number CT200175 designates Chevrolet Transmission, year, and 175th unit produced for service at Parma.

Upon completion of the serial sequence, the plant will reuse the above numbers using a letter prefix, such as A, B, or C to indicate late production transmissions; for example: CT2A0001.

PASSENGER CAR REAR AXLE IDENTIFICATION

Axles are manufactured by Buick, Chevrolet Buffalo, Chevrolet Gear and Axle, Oldsmobile, Pontiac and GM Of Canada (McKinnon). Divisional Manufacturer code letters will be metal stamped on the axle tube adjacent to the carrier for field identification. (See Example). Letters and numerals 1/4" high are metal stamped on right front inboard side, 3" outboard of carrier or are located on a metal tag attached to cover bolt.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
