Help decoding transmission numbers

[MoparMike1974]

I am trying to verify if the numbers on my 727 are matching to my car. So far everything else is matched. Here is what I have on the pad.
PK3681052 4140 5405
Its a 73 Dart Sport 340
Is the vin stamped anywhere on the trans?

4140 is Monday November 27th, 1972, if thats the build date of the trans, , it should precede the production date of the car,,,,if your car has a production date after 4140 then its at least dated correctly for the car,,

Any way to tell for sure if its the original trans? Nov 72 sounds like it could be.

this is how the decoding is broken down. The first 2 letters represent the ***. plant (pk or pp) the next is a 3 digit # that is the type of trans.After that is the build date followed by the 4 didgit daily sequence production #.
All trans that were installed from the factory will have the car's VIN (last 8 didgits of the VIN) stamped on the same pad as the serial #.
Now this code should be stamped on the front portion of the case on the pass. side just below the centerline.

Other side of trans should have a machined pad with VIN on it.
