To celebrate the 60th anniversary of its Hydra-Matic Transmission, GM Powertrain commissioned us to fully restore a 1940 Oldsmobile chassis and complete powertrain. After locating the vintage product in Indiana, we began our labor of love. We dismantled the entire assembly piece by piece and meticulously brought each component back to its original showroom condition. We then carefully crafted a cutaway display of the transmission housing. It was mostly about demonstrating the functionality of the Hydra-Matic system. However, a quality story came along for the ride.
