What Causes the Jerking Sensation When Braking in an Automatic Transmission Car?

[VonAshley]

Automatic transmission cars experiencing a jerking sensation when braking is often caused by sludge circulating within the transmission fluid, which can clog the oil passages in the valve body. Tips for transmission maintenance: Regularly check the automatic transmission fluid level—unlike engine oil, which is checked when the engine is cold, automatic transmission fluid should be warmed to approximately 50 degrees Celsius. Then, shift the gear lever through each position for 2 seconds before placing it in park. At this point, the dipstick's normal fluid level should be between the high and low marks. Add automatic transmission protectant to the transmission at a ratio of 5%. For older vehicles, it's advisable to add a bottle of automatic transmission leak stopper to restore aging seals and prevent leaks. Understand the replacement cycle for automatic transmission fluid: generally, it should be changed every 2 years or 40,000 to 60,000 kilometers. During normal operation, automatic transmission fluid operates at around 120 degrees Celsius, so it's essential to use high-quality transmission fluid.
