Spinning Levers - How A Transmission Works (1936)

 The transmission in the modern motorcar -- the mechanism that makes it possible to have three forward speeds and a reverse -- is a series of levers, levers that spin.

  1. That’s when General Motors made real cars and not the junk of today. Chevrolet Motor Division made a whole series of these films to educate the motoring public on how various components of a car work. Everything is explained thoroughly but in an easy to understand way so that you do not need to be a mechanical engineer to grasp it.

  3. I can't help but be reminded of the Turbo Encabulator. https://www.youtube.com/watch?v=Ac7G7xOG2Ag

  6. Transmissions are fascinating things. Especially in the simple times before synchros and during the time of straight cut gears. Those transmissions were amazingly easy to drive when you knew what you were doing and gave you a real feel for the rig that you were driving.

    Then there was the added plus of the sound they would produce as you passed a rig at 60 miles an hour on a two lane road. Between that and the sound of the passing rig's turbo it was a beautiful thing indeed.

    1. And then you can add the complexity of a 5 & 4, the 5 speed main and the 4 speed brownie or auxiliary, and that was a hoot to drive, to say nothing about the blue flame shooting a foot and a half from the top of the stack, blue if you were in the zone, and orange if you were pulling to hard. Yeah buddy, those were the good days. Course any days when I was younger were good.

    2. That was just before my time. When the guys with supercharged Cummins or Hall Scott engines would stand on the running board and watch the flame while pulling Bear Valley grade on their last run of the day as dark approached.

      My first truck was a '53 Kenworth with a two six-bits Cummins (supercharged). I never watched the flame but I sure loved the sound of that engine 'barking'. I only drove that truck for three weeks (1975) until the owner went broke. Good times.

  7. If only there was a time transmission. Would you go forward or would you go in reverse? Yep, me too! Ohio Guy

  8. My uncle when I was a yonker gave me a book on Archimedes. In several moves haven't been able to find it. I was looking for it a while back again. My sister in law said my brother claimed how strong I used to be but he was always stronger. I learned early on due to my size I had to apply leevereege as Capt. Jack Sparrow says.

  9. Video stated 9:40 duration, they don't say after 3:45 commercials. TLDW - wish I had the patience to, though.

  10. Cool video! Although I know a little bit about simple machines, I never realized that gears and gear reduction were based on levers. It makes perfect sense, but I'm just a MOron...

  11. Wow that is something like I would have watched in 8th grade. Now I’m guessing the movie would show how bad white man is for inventing cars.
