What Causes the Gear Shift Jerk in an Automatic Buick Excelle?
2 Answers
Reasons for gear shift jerk in an automatic Buick Excelle: Internal clutch pressure leakage in the transmission, requiring clutch inspection and repair; Unobstructed transmission oil circuit; Wear of the oil circuit plate; Deterioration due to prolonged lack of transmission fluid change, leading to reduced lubrication effectiveness; Excessive dirt in the transmission filter, allowing wear particles to enter the valve body. Below are the related introductions: 1. Automatic transmission gears: In the driving process of a car, the P gear is the parking gear, the R gear is used when reversing the car, the N gear is the neutral gear, and the D gear is the forward gear. 2. Troubleshooting methods: When the car experiences a jerking sensation during gear shifting, it indicates a fault in the car's transmission. It is necessary to promptly take the car to a 4S shop for transmission inspection, identify the fault by reading the fault code, and then carry out repairs based on the fault code.
I feel that the automatic transmission in the Buick Excelle has a noticeable gear shift jerkiness, possibly due to insufficient attention to regular maintenance. Dirty or insufficient transmission fluid can affect the smooth operation of the torque converter, causing a bump during gear shifts. If the filter is clogged, the oil passage is not smooth, and the computer-controlled shift signals become uncoordinated. Long-term driving in congested areas can also lead to excessive wear of the clutch plates, resulting in shaking. Another issue could be aging components, such as valve body problems causing unstable oil pressure. It's best to regularly check the fluid condition and recommend changing the transmission fluid every two years. If you notice any jerkiness, stop driving immediately and have a thorough inspection at a repair shop to avoid compromising safety.
