How to Match Gears with Speed?

[SanGabriel]

Methods for matching gears with speed: For manual transmission cars, the speed range for first gear is 0 to 20 kilometers per hour, second gear is 10 to 30 kilometers per hour, third gear is 20 to 40 kilometers per hour, fourth gear is 30 to 50 kilometers per hour, and fifth gear is above 55 kilometers per hour. For upshifting, accelerate first and then shift up; for downshifting, decelerate first and then shift down. In other words, the car should be shifted to the corresponding gear based on its current speed to avoid lugging the engine—this is proper matching. Upshifting should be done step by step without skipping gears. The same principle applies to downshifting: decelerate first and then shift down. However, downshifting can be done by skipping gears. Based on road conditions, reduce to a safe speed and then directly shift to the corresponding gear.
