Automatic vs. Manual Transmission: What’s the Difference?

Blueprint / technical explainer · 53 seconds · English

A 53-second blueprint explainer: a manual and an automatic gearbox solve the same two jobs, letting go of the engine and picking a gear, by locking one part. The difference is who does the locking.

How it was made.

The whole brief was the question, worded the way people search for it. The director picked the style itself. It opened both gearboxes on one living engineering drawing: clutch plates and a sliding collar, then oil between two fans and a planetary set.

The takeaway is one line: same gears, different hands, you or the car. It cost $6.19 of model spend to make.

Every film on explain.film is made the same way: one sentence in, a storyboard you approve, then the director paints, voices, scores and animates it, and a critic model grades the cut before you see it.

Transcript

  1. Your engine can't stop spinning.
  2. But at every red light, your wheels must.
  3. So a gearbox does two jobs: let go of the engine, and pick a gear.
  4. In a manual, that's you.
  5. The clutch pedal pulls two spinning plates apart.
  6. And the gears never slide together.
  7. They're always meshed, always turning; the lever slides a collar that locks one to the shaft.
  8. An automatic does both for you.
  9. Its clutch is oil: one fan swirls it to turn another, so at a red light, it just slips.
  10. To change gear, a computer clamps one part of a nested gear set still.
  11. Both change gear by locking one part.
  12. The only question is who: you, or the car.
