I got this Chevy T10 4 speed that was behind a 327 in a 32 ford coupe built in the late 60’s. Can anyone help identify what the trans originally came in. Thanks main case is stamped T10-1C 3782212 Tail is stamped T10-7D date 8-26-66 Side cover date 11-9-62 Has a number stamped on top 363S18683
from the chevy 1964 parts book. I don't know if this clarifies anything. The last couple lines might decode that WK thing
Maybe ordered tail shaft from Gm to replace it on this rebuilt 4 speed. the car has been sitting since 69 with the front collar on the other 4 speed cracked This 4 speed was sitting next to the old one
1961 Corvette early production started with cast iron main cases cast T10-1B. The tail shaft housings were aluminum. Aluminum cases appeared after VIN sequence number 2400. With a mix of aluminum and cast iron cases till around VIN 5500. All '62 Corvettes were equipped with aluminum main cases and tail shaft housings.
WK1723 is the transmissions build date and translates Warner Gear November 17, 1962, 3rd shift. If this trans main case started life in a '63 Corvette the VIN derivitive would be stamped vertically on the left side rear. The stamp on the top of the main case is not a typical factory stamp. It is individually hand stamped in a location not visible when the transmission is installed. Stampings for engines and transmissions in this time period were gang stamped. I'm reluctant to speculate but I will, it may be a rebuilder's stamp. I have included a typical 1962-3 factory stamp. This being a '63.
I wonder if it might have been a replacement installed at a dealership, and stamped by hand? I dont know what they did with the numbers on warranty replacement stuff on Vettes... I really doubt a rebuilder would be stamping a partial serial number on a transmission, like that. But we'll probably never know.
I think you make a very plausible suggestion. Problem being the 18683rd '63 Corvette is a late car likely built in the first week of July while the hand stamped date appears to be 3 63 or March 1963. Some time before the build of the 18,683rd Corvette. It may be a service part. Sold over the parts counter.
363S looks like a 63 Pontiac serial # built at the South Gate Ca. plant. My Catalina has the 363Sxxxxx serial # stamped in the same spot on the top of it's T-10.
If the 1/2 dozen 4-speeds I've owned since 1965 , 5 were put together with parts & pieces of other 4-speeds , its a real stretch to expect all the original parts to be together .
I posted a response then realized I was all wrong because what I was writing about was 1965 and after and didn't apply to this trans at all. So I deleted it. So does the first 3 in this VIN represent Catalina? The 63 that follows is the model year 1963? And the S is South Gate, California?

Yes that’s my kitchen table. So it’s looking to be a 63 Pontiac maybe? I got 2 4 speed transmissions from this house the other one has a broken snout collar was told he had this rebuilt to take place of the other in his 32 coupe I’ll post pictures of the other trans was behind a real deal corvette 327

He did have a 63 split window vette in the garage his son was keeping a lot of vette parts scattered thru out
