My trans is coded BA-67 and a serial number 7404. Above those is a 388 number that I believe is supposed to be a build date. I think this indicates I have a 67 GS400 correct trans but is there supposed to be some matching number to the VIN.?
I just looked in manual. Looks like BT for all Wildcat, Electra and Rivs and BA for GS400 BW code for Sportwagon 400
As the others already stated, BA is the correct code for a GS400. There will likely be no VIN on a '67 GS400 unless your car was built at Flint, even then, there might still not be a VIN. Neither of my Kansas City built '67 GS400s have a VIN on the engine or transmission despite being the originals. I've also got several spare '67 Buick ST400 transmissions, none have a VIN on them like we see with the later model cars.
Thanks for the input. Interesting you say the Kansas Cty cars often do noth ave VIN stamped on engine, and was puzzled mine did not have one. 53 K mi car and am certain it is original. Casting numbers all date correct. Maybe shouldn't have, but confess I stamped my VIN on blank spot. Suppose now someone might think a KS car with a VIN is a fraud.
In the 30+ years that we have owned and looked at ‘67 GS400s, we’ve never seen an original car from Fremont or Kansas City with the VIN on it except for a couple that were for obviously stamped later by someone other than Buick. I can’t say that Buick never stamped the VINs on these cars but we’ve not seen an original yet. A couple of years ago I saw a KC car being advertised as “numbers matching block” and it had VIN poorly stamped in an attempt to trick someone. As I mentioned above I’ve got two ‘67 GS400s that were both assembled at KC and there is a NR stamp and a date code on the deck of both original engines but no VIN. Both still have the original BA transmissions but also with no VIN. My spare NR engine and BA transmission are from an unknown ‘67 GS400 parts car that a friend had, also no VIN.
