<VV> Powerglide ID?

[Kent Sullivan]

Hi,

I checked my copy of Chevy Technical Service Bulletin #DR690 (9/1/64)
(picture of cover: http://www.corvairkid.com/images/65_Chevy_TSB_690.jpg)
and it says that the T is for Toledo, where apparently all PGs were built,
and the D stands for Day shift.

As far as production goes, Chevy prepared reports for each model year that
listed the last serial number built each month at each plant for each car
line, in order to track mid-year production changes. 164015 at Willow Run
was built during the month of December (1964).

I don't have my books in front of me, and it's been a while, so this
might be off.
 
T 11 25D looks like a build date code, perhaps T-  Tonawanda 
                                              11-  November
                                              25-  25th
                                               D-  1964, 4th year of
production
 
Your VIN, 40969W164015, 40969 denotes the model specs
                         W is for Willow Run
                         1 is for Chevrolet
                        64015 is for the 60,015th Car down the line
 
An engine and trans assembly built on Nov 25th might sit around for a
week or so, 
then go into a chassis. You'd have to know the production numbers for
the entire 
year, then divide by the number of weeks of production, then calculate
where the 
60,015th car would wind up in those weeks, figuring a fairly constant
daily production 
per week. You could have a car built early in December of 1963.
 
This has all been calculated for Corvette production during this period,
perhaps it 
has also been figured for Corvairs.
