What Causes Obvious Gear Shift Jerkiness?
1 Answers
The causes of noticeable gear shift jerkiness in a car may include clutch pressure leakage in the transmission, obstruction or poor flow in the transmission oil circuit, the use of inferior transmission fluid, or damage to the solenoid valve. While mild gear shift jerkiness is normal, severe jerkiness is abnormal, with common fault points possibly being the shift solenoid valve or control module in the automatic transmission. Below are detailed explanations: 1. Clutch pressure leakage inside the transmission. Inspect for clutch damage and carry out repairs. 2. Obstruction or poor flow in the transmission oil circuit. Wear in the oil circuit plate, long-term lack of transmission fluid change leading to deterioration and reduced lubrication effectiveness, excessively dirty transmission filter reducing filtration efficiency, allowing wear particles to enter the valve body. 3. Transmission fluid not filled to the standard level. Verify whether the transmission fluid is at the standard level, as both insufficient and excessive transmission fluid can cause this issue. For vehicles with a transmission dipstick, check during operation whether the dipstick indicates the standard level. 4. Solenoid valve damage. Sludge in the transmission fluid circulating and blocking the oil passages in the valve body can lead to jerkiness issues. Over time, this can cause a series of transmission problems such as overheating, impact, slipping, etc.
