TH400 Build date vs. car assembly date

[abefomen]

I have a '67 Camaro 04A build date.

I believe the trans to be original but I am unable to locate the partial VIN on it. I have read that it's not uncommon for some '67 TH400 to not be stamped.

The paint has worn off the tag but it reads as follows:

427 (Julian date=61st day of year...March 2nd)
CC = (Chevrolet/L35 engine) 6? (I'm going to assume it's 67 but the second digit is obscured)

10109= production sequence

My question: Is the trans build date of one month before the car's build date normal?


Thanks for the help.
