What causes the Civic to shake when braking in D gear?
2 Answers
The reasons for the Civic shaking when braking in D gear are as follows: Braking at high speeds: Actually, it's not the braking that causes the engine to shake, but the deceleration from high speed that leads to engine vibration. Matching issues: During deceleration, if there are problems with the transmission logic or the matching between the transmission and the engine, it can cause the engine to shake. If this is indeed the issue, it is recommended to conduct a thorough test. If the transmission also shakes, then it is likely this problem. In such cases, it's best to visit a 4S shop for professional diagnosis and have the technician inspect and repair it.
I'm a bit annoyed by the shaking when braking in D gear with my Civic. I think it's mainly caused by the lack of coordination between the engine and transmission. When the engine idles unevenly, it vibrates—for example, worn spark plugs or ignition system faults can transmit the shaking to the car body. Then there's the engine mount, which is supposed to cushion engine vibrations. If it's worn or damaged, the shaking becomes noticeable when braking. As for the transmission, in D gear, the engine is still delivering power while being held back by the brakes. If the torque converter or internal clutch plates aren’t smooth, it causes conflict, leading to car wobbling. Don’t underestimate this issue—ignoring it for too long may accelerate transmission damage and affect driving comfort. I’ll start by checking the spark plugs and engine mount condition, and maybe give the throttle body a simple cleaning.
