Re: 55 Packard Transmission Cooler Mockup ?

Randy old friend, I enjoyed your dissertation but what you fail to realize is that, logic, common sense, and facts are, to some, not relevant when forming a position.

Also, what seems missing in this discussion is appreciation for the fact that hydraulically actuated apparatus like a transmission are regulated by pressure which is a function of viscosity, which is a function of temperature. Now no one wants an overheated transmission, but the Packard factory unit was (presumeably) designed to keep the fluid within a certain temperature range which provided the viscosity which then established spring pressures, orifices, etc. So you could speculate that a radiator-mounted cooler, driving across Dave Kenney's country in February into a freezing wind, would result in viscosities and hence pressures outside of the engineering design parameters. Also I wonder how well a radiator-mounted cooler does crawling along in a July 4th parade on a 110 degree day when there is little to no air flow across it? I'm beginning to think that, if you must have an radiator-mounted air cooler, perhaps having it in series with the original as you have done may be the best answer.
