01D '67 - Powerglide w/ December '66 style stamp

[kforce]

Having a hard time deciphering the date code for my powerglide.
My car is a January '67 (01D)
According to "Chevrolet By The Numbers" The pan stamp is a '66 style code.
So, T 12 06N = Toledo - December 6th - Night Shift.
Is that December 6th, 1966?
So did the '67 and later style stamp that included the year start in 1967?
And are those the assembly date or Model Year?

Hope this makes sense.

I'd say it's an earlier trans. All 67 model year used the other forum - e.g. T7T04D.

Anyone out there have a '66 built camaro with a Powerglide that can list their PG pan stamp?
Or can CRG Record keepers please reply with some examples from registered Camaro's? Thanks.

So if it's an earlier trans, does that mean it was actually assembled in Dec of 1965? for 1966 production year, correct?

*Every* 67 powerglide has the format that I showed. No exceptions in the database.

Then the pan at least, for sure must be a '66 model year built in December of '65. Because anything built in December of '66 had to be a '67 Model year which would have contained the year in the stamp. The TH-400 in '66 and '67 had the assembly "DAY" of the "MODEL" year stamped. 372 of '67 meant 372 days from January 1 of 1966. Or January 7, 1967.  So now how do I find info on the actual transmission to find out if it is a '65, '66, or '67? The stamp for '65 and '66 were the same formula but had NO model year, or assembly year. Characteristics in the case would be the only way to identify it as far as I can tell. Anyone??
