What are the reasons for difficulty in engaging the first gear in a car?
1 Answers
Difficulty in engaging the first gear in a car may be caused by insufficient lubrication in the transmission, mismatch between vehicle speed and gear, synchronizer failure, or abnormal operation of the gear separation mechanism. Below is a detailed introduction regarding car gears: 1. Speed range: The first gear corresponds to a speed of 0-5 km/h. The second gear corresponds to 5-20 km/h, the third gear to 20-40 km/h, the fourth gear to 40-60 km/h, and the fifth gear to 60-100 km/h. 2. Gear shifting timing: Generally, the optimal gear shifting timing for most cars is when the engine speed reaches 2000 r/min, and should not exceed 2500 r/min. For high-displacement and high-power engines, shifting at around 3000 r/min is acceptable.
