Why does the Tiggo 8plus transmission have a jerky feeling?
2 Answers
If a car has a jerky feeling, it is definitely related to the two major components: the engine and the clutch. There are many factors that may cause the car to have a jerky feeling during startup and low-speed acceleration. Below are the most common reasons: 1. Engine oil passage blockage: First, focus on the engine. If the car has a jerky feeling while driving, the engine is certainly involved. The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is also the power source of the engine. If the air intake volume decreases, the ignition weakens, or the fuel injection reduces, the power will be insufficient, leading to a jerky feeling. 2. Clutch: For automatic transmission cars, a jerky feeling during startup is normal. If you want to accelerate quickly while driving, you need to press the accelerator pedal deeply. At this time, the automatic transmission will automatically downshift to increase the engine speed. When the speed reaches a certain level, it will upshift. After upshifting, because the speed will drop significantly, a relatively obvious jerky feeling will occur.
I've driven quite a few cars and also test-driven the Tiggo 8 Plus. I feel that transmission jerking is quite common, especially with dual-clutch transmissions where design issues might be a key factor. Dual-clutch transmissions aren't very smooth when shifting at low speeds or in traffic jams, which can easily cause jerking. This might be due to poor clutch engagement or suboptimal control software logic. For example, during rapid acceleration or when suddenly releasing the throttle, the computer might inaccurately judge the shifting timing, leading to body vibrations. Some people also report that new cars during the break-in period can exhibit this issue, which might improve as mileage increases. However, it's advisable to pay attention to driving habits—avoid slamming the accelerator or frequent speeding up and slowing down. If the jerking is severe, it's best to get it checked at a 4S shop. A software update or hardware adjustment might be necessary, as this not only affects comfort but could also damage other components. During regular maintenance, it's also important to check the condition of the transmission fluid, as aging fluid that isn't replaced in time can exacerbate the problem.
