Thanks for posting the article. I found the reference to Dynaflows to be not entirely accurate as a properly sealed dynaflow does not present a real leakage problem. Certainly no worse than other automatics of the period. Technical inaccuries also. eg: "dynaflow varies the pitch of the torque converter". Actually varies the pitch of the first stator blades which alters the stall speed thus the converter ratio. We already have a whole group of "modern" dynaflows in the form of CVT's. I currently own a Ford Freestyle with the CVT. It behaves differently from a dynaflow but gives the same solid, consistent thrust on acceleration. Other designs are near production - notably the IVT - infinitely variable transmission. ToroTrac is the trade name for a roller version of this trans that may soon see production. Any of these designs provide, in theory, a much improved driving experience over a conventional step gear auto. Trouble is, so many drivers only frame of reference is with rising rpm, shift, rising rpm feel. They initially do not appreciate the huge advantage of always having just the right ratio. The feel is foreign to them and therefore it seems wrong. The "hydristor" is a fascinating design that would appear to have just as much development potential as these other designs. Thanks again for the reference.
