avgwarhawk Posted April 13, 2017 Share Posted April 13, 2017 I never really understood how a converter operated until I watched this 13 minute US Army informational video created in 1954. It is simplified but enough to understand what is going on under that transmission hump. 3 Link to comment Share on other sites More sharing options...
JohnD1956 Posted April 13, 2017 Share Posted April 13, 2017 That was a great video! Thanks for posting it. I have read the manual several times but never really understood how the torque converter worked. Now I'll be thinking about all that everytime I drive. 1 Link to comment Share on other sites More sharing options...

I kind of had an idea but never really delved into it. Fluid coupling is ingenious. There are some folks that not only think outside the box but also engineer the box. One of these "outside the box" is the Dynaflow. Link to comment Share on other sites More sharing options...
60FlatTop Posted April 13, 2017 Share Posted April 13, 2017 Before the microprocessor base variable frequency drives for electric motor, 40 years ago, we used the same fluid drive converters for pumps. I used to take care of a bank of fluid drive VSD pumps for a large dialysis unit in a hospital. They had a knob to set the nozzle flow. Old technology, even the Dynaflow, triple reverse acting waterwheel.. Back in those days I also had a computer monitor that indexed a slide carousel, selected a slide, and back lit it on a TV style screen, Honeywell Selectographic. 1 Link to comment Share on other sites More sharing options...
Joseph P. Indusi Posted April 13, 2017 Share Posted April 13, 2017 The video illustrates the operation of a fluid coupling. This what was used in the early Hydramatic transmissions. When a third element, the stator, is added to the pump and turbine, the result is a torque converter. This is similar to the fluid coupling but this video does not illustrate the action of a torque converter. The Dynaflow transmission used a torque converter and not a fluid coupling. There are several videos on You Tube that illustrate the action of the torque converter. Joe 2 Link to comment Share on other sites More sharing options...
PWB Posted April 13, 2017 Share Posted April 13, 2017 Best auto trans. video I've seen. They spent a small fortune fabricating the transparent housing, I'm sure. And dad better get on those Dandelions! The Jones' wont appreciate it. Thank you for the vid! Link to comment Share on other sites More sharing options...

Pascal's law and a kind heart will be around forever. I'll bet your expertise extended many lives. Kudos, Mr. Bernie Link to comment Share on other sites More sharing options...

My father was big into photography and had his pictures on slides. He would load in the carousel for us to look on a screen. Link to comment Share on other sites More sharing options...

It is quite a clever design. Link to comment Share on other sites More sharing options...
