What to Do When an Automatic Transmission Car Shakes During Start-Up?
2 Answers
Automatic transmission car shaking during start-up should be addressed by removing the ignition coil to check for rust on the contacts and observing whether the screws are tightened. Here are some explanations regarding the shaking during start-up of an automatic transmission car: 1. Reasons for shaking during start-up of an automatic transmission car: Poor fuel flow, where insufficient fuel supply at low throttle causes uneven operation of the engine cylinders, leading to shaking. A dirty throttle valve causing uneven air intake and operation results in shaking. Broken or burnt high-voltage wires or spark plugs causing a cylinder to misfire leads to unstable engine operation and shaking. Abnormal transmission operation. 2. Inspection recommendations: It is recommended to check whether the fuel pump and fuel supply lines are functioning properly. The likelihood of transmission issues is relatively small.
Having driven automatic transmission vehicles for over a decade, I've encountered startup vibrations on numerous occasions, each time worrying it might be a serious issue. From my experience, this is often the result of accumulated minor issues – like aging, loosened engine mounts causing body sway during acceleration, or old, contaminated transmission fluid affecting smooth gear shifts. Uneven tire pressure or irregular tread wear can also induce vibrations, especially during low-speed starts. My advice is to first conduct simple self-checks: kick the tires to detect abnormalities and inspect fluid conditions. If the issue persists, don't hesitate to visit a professional repair shop immediately. Neglecting minor problems risks collateral damage to other components, ultimately increasing repair costs. Cultivating regular maintenance habits, such as comprehensive biannual inspections, effectively prevents such issues.
