Of all the posts I've seen, one which has been overlooked is the one about the Cadillacs which were burdened with DYNAFLOW transmissions during the 1953 and possibly 1954 model year.

This was the result of the fire at the GM HydraMatic factory in Livonia, Michigan, a fire caused by a welder's spark that led to insurance companies telling their inspectors to look for buildings with a "Livonia Roof" since the fire spread so fast and wiped out the whole factory so quickly.

As a kid I rode in a neighbor's 1953 Fleetwood with that Dynaflow transmission and it was a weird sensation. My father had an Oldsmobile 98 and I kept waiting for the sound of the motor in that 53 Cadillac changing its note as it shifted, but that sound never changed. Odd, to say the least.
