What Causes D Gear Shaking in Cars?
2 Answers
If you shift into D gear but keep pressing the brake, some noticeable shaking at this time is a normal phenomenon. If there is still significant shaking when driving after shifting into D gear, it may be caused by aging transmission mounts. In this case, it is recommended to check the transmission mounts. If the mounts are indeed aged, they need to be replaced with new ones. Below is an introduction to dual-clutch transmissions: 1. Dual-clutch transmissions are currently the hottest products. This type of transmission is actually developed based on manual transmissions, and its structure is quite similar to that of manual transmissions. 2. Dual-clutch transmissions only have one more clutch and one more gear-shifting control mechanism compared to manual transmissions. One clutch in this type of transmission controls the odd-numbered gears, while the other clutch controls the even-numbered gears. 3. Dual-clutch transmissions offer fast gear shifting and high transmission efficiency. Many performance cars and supercars use dual-clutch transmissions because they provide drivers with a crisp and decisive shifting experience. 4. There are two types of dual-clutch transmissions: dry and wet.
My car keeps shaking at D gear when waiting at red lights, just like a massage chair. This situation is mostly caused by aging or cracked engine mounts, as rubber parts lose elasticity over time. It could also be due to excessive carbon buildup in the throttle body, leading to unstable idling; or problems with ignition coils and spark plugs, as misfiring cylinders can cause severe shaking. Additionally, dirty transmission fluid or unstable oil pressure might be the culprit, especially for older vehicles with over 100,000 kilometers. If shifting to neutral feels better when parked, it's basically an engine-side issue. Anyway, don't delay and get it checked soon, otherwise the shaking will worsen and cost more to repair.
