Causes of jerking and stalling when shifting gears of automatic transmission vehicles and how to fix them

In today's car market, the use of automatic transmission cars is becoming more and more popular. Over time, many drivers are facing annoying problems such as automatic transmission cars jerking and stalling when shifting gears. This is not only annoying but also poses challenges to traffic safety.

Automatic transmission vehicles do not depend on the driver when shifting gears, so if the vehicle shows symptoms such as difficulty accelerating, slow shifting, high rpm, jerking, or stalling when shifting gears, it may be due to lack of oil. Transmission oil plays an important role in the movement of the vehicle, and if there is a lack of oil, the smoothness of the gear shifting process will be significantly affected.

The vacuum damper is the part that helps the vehicle determine when to shift gears. If this part is no longer working properly and has a problem such as a leak or broken diaphragm, the vehicle will not be able to determine when to shift gears correctly, resulting in jerking or uneven shifting.

Many newer vehicles use sensors to help the system know when to shift gears. If this sensor is faulty or damaged, the vehicle may jerk or stall when shifting gears. Checking and replacing the sensor is important to maintain the performance of the system. Components such as the transmission belt, clutch, oil filter, oil pump, and friction plates inside the transmission can also cause an automatic transmission to jerk or stall when shifting gears. These components can wear out and need to be checked periodically to ensure smooth transmission operation.

For drivers, regular maintenance and taking their vehicle to an authorized garage when problems arise are key to keeping their transmission running smoothly. Regularly checking the transmission fluid, vacuum regulator, sensors, and other internal components of the transmission will help avoid unwanted problems down the road. While vehicle manufacturers often recommend that transmission fluid last “the life of the vehicle,” checking and replacing it when necessary is still a safe and effective way to keep the system running smoothly.

Regular monitoring and maintenance will not only keep your car running smoothly, but also keep your journey safe and enjoyable. Keep your car in the best condition.
