請問開車時未暖車就開車,為啥偶然人波會挫和發出機械碰撞聲

開車時未暖就開車問題大嗎?最近發現我的車不知為啥有時一人波會挫和發出機械碰撞聲,好大聲,雖然不是每次都響,但己很嚇人。是否暖車未夠就人波開車,令到某個齒輪崩左,所以發出機械碰撞聲,有危險嗎?要怎麼樣的維修才不會導致再發出機械碰撞聲,在開車時。是否一定要暖車到車速的針回落後才人波,但很浪費時間.是否我己把車弄壞拉?請指教!

    Engine oil and transmission oils require a certain temputure to be functional. When the oil reach a specific temputure, it sticks and protects the metal surface from scratches. Without a proper warm up, you WILL wear out the engine and transmission and other power steering componments. If you think that is waste of time, try to warm up for 2 minutes and drive slowly and gently until it reach working temputure.

    For your transmission problem, you should first change your transmission fluids. It sounds like you have not change the transmission fluids for a long time, It may contain loose metal which causes you problem shifting smoothly. Get a quality oil with proper weight will improve a lot!
