'''Dynaflow''' was the [[trademark]]ed name for a type of [[automatic transmission]] developed and built by [[General Motors Corporation|General Motors]] [[Buick]] Motor Division from late 1947 to mid-1963.<ref name="Flory, Jr. 2008">{{cite book|last=Flory, Jr.|first=J.

It was also used in the 1951 [[Le Sabre concept car]].<ref>Flory,  J. "Kelly", Jr. ''American Cars 1946-1959'' (Jefferson, NC:  McFarland & Coy, 2008), p.1021.</ref>
