I am an Oldsmobile guy and I bought a large load of Oldsmobile parts a couple years ago. This 71 OW transmission was part of the deal. I never knew it was a Buick transmission till today when I looked at the VIN. Is there a registry for 71 GS cars? Would an OW in a Buick only be found in a stage 1? I am going to sell it but prefer to attempt finding the original car to the transmission first. I figure the car is long gone but you never know. If there is a registry I would like to see of this transmission's VIN is on there. The VIN is stamped real high and it makes it hard to read.
