Cadillacs with Dynaflow
I had read about this before too Steve. Here is the clip from Wikipedia about this:
The early 1950s Cadillacs were normally equipped with Hydramatic transmissions. In 1953 the General Motors Hydramatic Plant burned to the ground, leaving Cadillac without a source of transmissions. Buick Dynaflow transmissions were hastily adapted to Cadillac mount points, and some 19,000 1953 Model 62 Cadillacs, and some 28,000 Cadillacs of all models, were equipped with Dynaflow transmissions. Several thousand 1953 Oldsmobiles were also equipped with Dynaflow.
I owned a 67 Buick Skylark 2 dr HT from the spring of 76 til the fall of 81. The car was without doubt the most favorite car I ever owned. The Twin Turbine Dynaflow was a smooth as silk and I consistantly got 19 mpg. I know this because the float for the gas gauge stuck for about a year, so I had to keep track of my milage so I wouldn't run out of gas, which never happened. Then one day when I went over some RR tracks fast the gauge suddenly began to registar again, the float must have been rusted and the sharp movement shook it loose.
I also owned a 55 Cadillac Coupe DeVille for about 8 months in 74. That big old boat just floated, but big as it was I used to parallel park it in downtown San Francisco, and it took the curves of the north coast Hwy 1 like a much smaller car, handled with ease, the power brakes were very good, little fade and they didn't grab like a lot of the power brakes on 50's and 60's cars. But the gas milage, terrible! I could actually watch the gas gauge go down on the Waldo Grade. It got about 8 mpg and used a quart of oil with every fill up. But for a 19 year old car at the time, with 100,000 plus miles it really flew. And if you've never driven a car with vacuum wipers before, its a different experience. They will slow to almost a stop on acceleration. The Hydramatic shifted smoothly and predictably. I got rid of it because it was a money pit and there was gas rationing, but I sure enjoyed that Cadillac while I had it. You could squeeze four in the front and another four in the back, so it was popular with friends.
