On the Super Turbine 300 2-speed automatic, the transmission code was stamped on the low-servo cover on the passenger’s side of the transmission or on a metal tag.
The 3- and 4-speed M20 and M21 manual transmissions were used on the GTO and, generally, but not always, had the part number stenciled on the transmission case on the driver’s side of the case, at the rear of the cover. The code number indicated the type of transmission and the production date.
An identification code is marked in yellow paint on top of the case on 4-speed transmissions: W stands for wide-ratio and 9 stands for close-ratio. On the 3-speed Tempest (Muncie), the letter X indicates a heavy-duty Muncie and is marked on the passenger’s side of the case. The letter S identifies a midyear (March 1) introduction of the 3-speed manual Dearborn transmission.
1965 Rear Axle Identification, Codes and Ratios
In 1965, differential codes were stamped on the back passenger-side axle tube. The codes identify which axle ratio was used and if the axle was equipped with Safe-T-Track.
The GTO has the following items as standard and were not available on other LeMans models: the vinyl-trimmed assist bar over the glove box door, a GTO emblem located to the left of the assist bar, and a GTO emblem mounted on each door.
Exterior color codes can be found on the cowl data plate located on the driver’s side of the firewall.
The hardtop and coupe were also very stylish, especially with the Cordova vinyl roof. Note the 6.5 emblem on the front fender, while the GTO was placed on the rear fender.

Option Groups
Compiling multiple options into a single option group was a way of creating less confusion and paperwork for dealers.
The 1965 Convertible had a more up-to-date front grille, which was a precursor to the 1966–1967 GTO. Compared to the simulated scoops used on the 1964 GTO, the 1965 hood scoop looks functional.
Is My Pontiac LeMans a True GTO?
The GTO option was listed as an option on the LeMans Series for 1965 and not a separate, freestanding model. In addition, the engine can easily be substituted by another engine because there is no code for the engine in the VIN. On the other hand, an original GTO must include the hood scoop, front fender GTO crests, rear fender GTO emblems, and a rear deck GTO emblem. The interior includes a vinyl-trimmed assist bar over the glove box door, different GTO emblem located to the left of the assist bar door, and mounted GTO crests on each door.
The GTO received its first restyle in 1965. The GTO was still an option package on the two-door coupe, hardtop, and convertible LeMans.
Exterior
The front end of the car had a totally new look with vertical headlights and a split, recessed grille. The new front end was deemed to be more modern and fresher than the 1964. The hood had a simulated single hood scoop; however, the scoop became functional later in the model year with a dealer-installed Ram-Air system.
