What Causes the Low-Speed Jerking in Cadillac?

It may be due to engine oil passage blockage or transmission damage. The following are relevant extended information: Engine oil passage blockage: The combustion of fuel, which is also the power source of the engine, is determined by the engine's ignition, air intake, and fuel injector. If the air intake decreases, ignition weakens, or the fuel injection reduces, the power will be insufficient, resulting in a jerking sensation. Transmission damage: Persistent dirt and impurities inside the transmission can cause jerking. During the new car break-in period: The power output of a new car and the meshing of components are not at their best level. Additionally, the transmission computer has a self-learning mechanism that requires continuous adjustment of oil pressure for gear shifting, thus causing a jerking sensation.

If your Cadillac feels jerky at low speeds, such as during traffic jams or when starting off, causing the car to lurch, this may be related to the automatic transmission system. Having driven similar models, I've found that it's often due to wear in the torque converter or clutch components, leading to insufficient oil pressure or delayed gear shifts. Additionally, check if the transmission fluid is too dirty or insufficient, as these can also cause jerking sensations. Another factor could be engine-related components, such as carbon buildup in the throttle body or spark plugs, affecting the smoothness of power output. Don't underestimate this issue; continuous jerking can wear internal parts and increase repair costs. It's recommended to visit a professional shop as soon as possible to scan for error codes. You might need to clean or replace fluids to maintain driving comfort and safety.

My Cadillac has been jerking a lot at low speeds lately, making the driving experience really poor. I asked my mechanic buddy, and he said it could be a transmission control module failure or the software needing an update, especially for high-end cars like this where the systems are more complex. Sometimes it's because a sensor is broken and not sending feedback signals in time, or it's more noticeable during cold starts. I thought regular checks of oil pressure and electrical circuits might help, but even after trying to check the oil level myself, the jerking persisted. In the end, I took it to the dealership, and after they updated the computer program, it got much better. I recommend you also get a professional diagnosis to avoid letting it turn into a more serious issue.

When driving a Cadillac to and from work, I experience jerking at low speeds, which makes me feel uncomfortable. This is often caused by torque converter slippage or clogged oil passages in the transmission, leading to uneven power delivery. It could also be related to the ignition system, such as aging spark plugs causing unstable engine RPM. During my bi-annual maintenance, I always have the mechanic inspect these components to prevent minor issues from escalating. If ignored, the jerking not only affects driving smoothness but may also accelerate internal wear and pose safety risks. Addressing it early saves money and hassle.
