Is It Normal to Hear Abnormal Noises When Starting the Car and Shifting into Reverse Gear?
2 Answers
It is not normal to hear abnormal noises when starting the car and shifting into reverse gear. Possible causes include abnormal gear engagement or aging car components, which require timely inspection and replacement. Below is a detailed introduction about car gears: 1. Speed range: First gear corresponds to a speed of 0-5 km/h. Second gear corresponds to 5-20 km/h, third gear to 20-40 km/h, fourth gear to 40-60 km/h, and fifth gear to 60-100 km/h. 2. Gear shifting timing: For most cars, the optimal shifting time is when the engine speed reaches 2000 r/min, and should not exceed 2500 r/min. For some high-displacement, high-power engines, shifting can be done around 3000 r/min.
As someone who has been driving for over a decade, I often encounter such issues. Abnormal noises when shifting into reverse during vehicle startup aren't necessarily normal—it depends on the specific type of sound. A slight clicking noise might just be the normal sound of the brake system breaking in under low temperatures or damp conditions, similar to when the handbrake isn't fully released. However, if the noise is sharp or keeps rattling, then there's likely an issue—possibly due to worn transmission gears or insufficient fluid. Worn transmission gears increase friction during gear shifts, which can damage the car and hurt your wallet over time, so it's best to check if the fluid needs changing early on. Gear-shifting noises are also common with clutch system failures, especially in manual transmission cars during cold starts when parts stiffen. For safety, if you notice anything unusual, don't hit the road immediately. First, check the transmission fluid level yourself. If you can't figure it out, take it to a repair shop for a mechanic to inspect with a diagnostic tool. Regular transmission maintenance can prevent such issues—don't overlook this detail, as it can save you a lot of trouble down the line.
