I have this transmission which I believe is for a 1969 Chevelle. Production date is P9S09A which would be a Nov 9 1969 M20.
The VIN derivative has me scratching my head. It reads 19K354417. My interweb research leads me to think Chevelle, but the leading "1" is throwing me off.
The "1" at the beginning of the VIN indicates Chevrolet Division (Pontiac at the beginning of the VIN was "2", Olds "3", Buick "4", etc). The "9" would be the model year and the "L" would be the Leeds, Missouri assembly plant which built A-body (Chevelle, LeMans, Cutless & Skylark) GM cars, so it did quite likely it came out of a Chevelle. The assembly date of the trans is November 9, 1968, not 69. Like the "9" in the VIN, the "9" after the "P" in "P9S09A" is the model year, not the year it was assembled. A trans assembled November 69 would have gone into a 1970 model, not a 69.
Most Chevy engines (and transmissions) that were stamped with a partial VIN, starting around 1969, include the carline, as noted 1 means Chevy car. But you'll also find C and T and sometimes 2 on the partial VIN on Chevy engines, C=Chevy truck, T=GMC truck, 2=Pontiac, etc.
1960s Corvettes were strange in that they got a partial VIN on the engine, and since nothing else did, they didn't need the leading 1.

GM started stamping a partial VIN on Corvette engines in mid 1960, and shortly after started stamping them on all higher horsepower engines in other Chevrolets. Generally anything 300 hp and over in full size Chevy's, Chevelle's and Chevy II's got a partial VIN stamp. Starting in January 1968 Federal law required every car sold in the US to have a VIN stamp on the engine and trans in an effort to combat car thefts.

Makes sense, thanks for the education.............. Wonder if the car is still in existence that it came out of.
