1969 Saginaw 3sp Tranny Code

[Richard H.]

Would anyone know the main case number for a 1969 Corvette Saginaw 3sp transmission? I thought it was 3925647, but I may be mistaken. Thanks. Richard

GM #3925647 was, indeed, the casting number for the 3 speed manual transmission case used for both 1968 and 1969 Corvettes. It was also used for most other 1968 and 1969 Chevrolet cars with 3 speed manual transmission. This is a cast iron case, of course.
