How about a Cadillac with a Dynaflow transmission?
(from Wikipedia) A massive fire that destroyed GM's Hydra-Matic plant in Livonia, Michigan on August 12, 1953 left the corporation and the three divisions that used this transmission scrambling for other sources of automatic transmissions to complete that year's model year production. As a result, Oldsmobiles and Cadillacs during the downtime were assembled with Buick's Dynaflow transmission, while Pontiacs used Chevrolet's Powerglide, both two-speed torque-converter units. Non-GM makes that bought Hydra-Matics from the corporation, including Ford Motor Co.'s Lincoln division and independent automakers Hudson, Kaiser and Nash, ended up looking for other sources of automatic transmissions as well, with Lincoln using the Borg Warner designed Ford-O-Matic transmission, while other automakers also switched to automatics from Borg-Warner during the downtime.

About nine weeks after the Livonia fire, GM opened up a new source for Hydra-Matic production at Willow Run, Michigan. By the time the 1954 models debuted in late 1953, Hydra-Matic production had returned to normal levels and all '54 model Cadillacs, Oldsmobiles and Pontiacs with automatic transmissions were once again equipped with Hydra-Matics.
