I just bought a 67 Chevelle SS from a guy. The transmision is TH400 short shaft. The numbers are as follows:
On the right hand lower bell housing:
C8A132785
Then on the rear out put shaft housing:
Lester-4
8624486
On the alum Tag riveted to RH side of case is:
338
9-CW- 1563
Can we date and find out what it came out of?

From my TH400 book, "The ID code gives the model year, a two digit division and calibration code, and a serial number. Some have a second line indicating the day the transmission was built."

Given the above I'd say you have a 1969 Chevrolet TH400 built on the 338th day of the year. The only problem I see from my reference is that the first CW code shows as being for a 1970 Chevelle, V8 400CI. The codes don't show a 70 402, so I'd bet the 400 meant the SS Chevelle 402.

Perhaps the late build date in the year meant the trans would show up in a 1970 car?

Sorry I can't be more definitive, maybe others have a better reference for the other numbers.

John:

I don't have info. with me at work, some but not much... The main case part # is 3823462.

Location of of turbo 400 date code is supposed to be stamped on that small metal tag riveted to right side of the main case and is a Julian date system, not like a typical calendar year. Production of the 67 model year started 8/1/66 which is day 213 Julian, Dec. 31 would be day 365 and and Jan 1 would be day 366 and continues until final production day 577 7/31/67 I am pretty sure the "C" = 396 Chevelle I believe the A would be for January and the 8 might be for 68?? or 8th day January ? sorry I can't really be more useful here...
