You must have a 65. The 65 transmission code is a 1965 code. (Torqueflite) Make sure the build sheet is for your car. What is the VIN? The 1963-65 codes are pretty sketchy.
That is a good question I didn't look at that it came out of the back seat in the car when I got it it's definitely a manual car or they did a really good job at faking it including the rusted out floor thank you
