Sweeeeeett:TU: At least I have a #s match, date coded factory installed carb on my car that the numbers can be seen as well as a #s match block, and rear axle. All in all, if the only thing that was swapped out was the tranny, I am happier than a pig in you know what... Thanks for all the help everyone. Brian
It must be that rare Oldsmobuick transmission....so rare it took 2 years to build:laugh: Seriously, it is most likely a rebuilt unit that had the governor cover switched when it was rebuilt. Ron Sessions mentions this in the Turbo Hydra-matic 350 book. Thats the problem with putting numbers on removable parts. Makes it really hard to figure out what you have. Apparently, its not uncommon for rebuilders to have piles of pans, governor covers accumulater covers, etc. laying around and they just use the one on top. So, we know you have a case from a '74 Buick and a governor cover from a '76 Olds.....if there's a number on the pan, maybe we can figure out what it came from o No: BTW Marco, how do you know that it came from a Buick for sure. I always thought a partial VIN like the one listed would be missing it's first few digits, ie:xxxxx44X123456. Since the first digit of a VIN denotes division, wouldn't the first 4 in this example be an engine code, or am I not reading it right. I really don't have much info on VINs after '71, so I'm curious.
Thanks Darren - On serial number stampings, the division is the first digit ('4' for Buick, just like the VIN), next came the model year, then comes the manufacturing plant and the 6 digit serial number. For example, if you had a 1971 Buick GS with a VIN 434371G123456, both drivetrain components would have a serial 41G123456 stamped on them.
