Hi,
I am new to the site, I joined hoping that someone could help me decode my build sheet. I am particularly interested in what transmission my car came with. The trans code on the build sheet is 779. I will attach a copy of the sheet. I just started restoring the car I drove in highschool, and found out that someone "misplaced" the transmission for me at some point in the last few years. I have a 318 from a 67 dodge van in it with a better cam shaft, a high rise intake, and a 4-barrel carb on the top. Otherwise, nothing should be different from the factory setup. I am trying to figure out exactly what transmission I need to put back onto the car. I dont know if it should be a 727 torqueflight or a 904. I am also not sure what length trans I should be looking for. Any help is appreciated. Thanks!

What code does your fender tag show? bottom row, second in from the right. My 72 came with a 904. It's a 318 with power disc/drum , power steering and AC... Not sure these options matter in whether or not it was built with 904 or 727. 904 is considered "light duty"

My Dart has code 804 and it is a904 transmission, so by default i would think 779 would be for the 727 trans.

Looks like D31 on my plate. Some googling tells me it should be an A904 transmission.

all 1970 Darts with a factory 318 and automatic came with a 904. 5th character in your VIN is a G which confirms that it came as a 318 car.
