[QUOTE="Josh"] I had a neighbor with one of those '41 fluid drive Cryslers. Being young and curious about cars, I found it surprising that the neighbor would pay so much more for his fluid drive Chrysler, when it was a noisy high rpm slug off the mark compared to our cheap 36 Chev 6 cyl .[/QUOTE] Josh, You have to remember that people were looking to "NOT" having to shift all the time. I remember my grandfather always starting out in second gear, then slipping it into third as quickly as he could. He got into fluid drive when he started buying Dodges, and never went back to any other make. As to the cost, Fluid Drive became standard on three car lines: Chyrsler, DeSoto, Dodge. This reduced the cost by having just one transmission. It was not the transmission that people were paying for, it was the"trim" levels, interior "luxuries" etc. As to noise, it is silent, no gear clashing. It is kind of like the CVT transmission that when it gets into gear,it just gains speed without a lot of noise. Also, people were not really interested in "off the mark" and "O-60" times until car testers started these measurements when the V-8's became the norm. Over 52% of Chrylsers were 6 cylinder, all DeSotos were 6's and all Dodges were 6 cylinder. The 48% of Chryslers that were not sixes were straight 8's. Then, in 1951, the hemi V-8 came out for Chrysler, later Desoto and Dodge, but still the majority of cars sold came with the flathead six. Chrysler only changed from Fluid Drive when the V-8 needed a transmission that could handle the torque and HP generated, then Chrysler came up with the PowerFlite, later the Torque Flite. But Fluid Drive lasted from 1938 until 1953, and millions of cars were sold with them.
