What is the impact of coasting in D gear on the transmission?
1 Answers
The impact of coasting in D gear on the transmission is that it puts a load on the transmission, and prolonged use can cause the clutch to overheat or wear out. Reasons for the impact: When the vehicle is in D gear with the brakes applied, the transmission is under load. To cope with this load, the engine also increases its load, meaning it increases fuel injection and raises the RPM. Some engines and transmissions are not well-matched, or the engine's power may have decreased, leading to shaking. For dual-clutch transmissions, the clutch is in a semi-engaged state during this time, and prolonged use can cause the clutch to overheat or wear out. How the transmission works: The transmission primarily applies the principle of gear reduction through gear transmission. In simple terms, the transmission contains multiple sets of gear pairs with different gear ratios. The act of shifting gears while driving involves the operation of different gear pairs within the transmission. For example, at low speeds, gear pairs with larger gear ratios are engaged, while at high speeds, gear pairs with smaller gear ratios are engaged.
