What is rev-matching in a manual transmission? The idea is if you want to shift to a lower gear in a manual transmission vehicle, rev-matching allows for a smooth shift. For a given vehicle speed, the higher the gear you’re in, the lower your engine’s speed. So to downshift from 4th to 3rd the engine speed is going to increase. To compensate for this, the shift is as follows: you push in the clutch, blip the throttle (raising the engine speed to match the next gear), shift from 4th to 3rd as your engine speed climbs, and then let out the clutch. It’s easier on your vehicle, and doesn’t upset the car’s balance while shifting.
