whats these numbers mean?

This guy seems to think the last two digits are the year model,meaning yours would be a 63" transmission.

What year is my 727 torqueflite Tranny?
I cannot find anything that will tell me the year the tranny is...Here,s whats on the side of the tranny right above the pan...J2801541 then 3413976...It,s in a big block 67 b body...
Thanks MoPar heads!!!

those are just casting numbers found on mostly all 727 transmissions,from what i get from the numbers it could be anything from a 70 to a 76 model,those are the exact same set of numbers i got on mine except for the last last two numbers,mine last two are 70 which should indicate the year of it,yours should be a 76 model,it doesn't matter on parts because all inner parts are the same on the ones from 76 and back,its not original to your car though ,its to new to be original,good luck.
