Thanks for the link. It’s funny - at the end of the film they have a scenario where someone is testing downshifting on an automobile. The narrator describes how the young lady will accelerate to 60 mph going down a grade and then downshift to second.
She is driving a 1936 Chevrolet sedan. Those cars typically had a 216ci six behind a 3-speed transmission and a 411 rear differential. That means that 60mph was close to top speed and near the top end of the engines RPM range.
And she’s gonna downshift?!
you are right. IIRC Those cars had a very weak axle that you could break just by popping the clutch too hard...
