What Causes Severe Transmission Jerking in the Buick Excelle?
2 Answers
The accumulation of dirt and impurities inside the transmission valve body of the Buick Excelle leads to blockages, preventing effective regulation of oil pressure and resulting in jerking, impact, and slippage issues. Below are relevant details: 1. Naming Convention: The Buick Excelle models are named using a combination of numbers and letters, where the numbers indicate engine displacement and the letters represent the engine type. For example, in '15n,' '15' denotes a 1.5-liter engine, and 'n' signifies a naturally aspirated engine. 2. Dimensions: The Buick Excelle measures 4587mm in length, 1798mm in width, and 1463mm in height, with a wheelbase of 2640mm. It is equipped with a 6-speed DSS intelligent transmission, delivering a maximum power of 120kw and a maximum torque of 230nm.
The transmission jerking issue in the Excelle is quite common. From my personal driving experience, it's mainly caused by aging or insufficient transmission fluid. Dirty fluid can affect the smoothness of gear shifts. Additionally, software malfunctions in the electronic control unit are another reason. For instance, my car once experienced an error during a system update, causing the transmission to jerk during acceleration. Mechanical components like clutch wear or sensor failure can also trigger jerking sensations. I remember one time on the highway when the jerking was particularly noticeable, almost causing a rear-end collision. I immediately took it to the 4S dealership for inspection, and after changing the fluid and updating the program, the issue was resolved. Don’t ignore this problem, as delayed repairs can increase the difficulty and cost of maintenance. It’s advisable to develop a habit of regularly checking the transmission to ensure smoother driving.
