What are the reasons for severe transmission jerking in the Cadillac XTS?
2 Answers
Cadillac XTS transmission jerking severely for the following reasons: Excessive carbon deposits: Due to excessive carbon deposits on the throttle body, fuel injectors, and intake passages, it is recommended to regularly clean the carbon deposits. Poor fuel quality or spark plug issues: Due to poor fuel quality leading to incomplete combustion, or possible faults with spark plugs, ignition coils, etc., causing cylinder misfires. This requires inspection and repair at a maintenance facility, and timely repairs should be carried out to avoid more potential safety hazards. Engine problems: Engine ignition, intake, and fuel injectors collectively determine fuel combustion, which is also the power source of the engine. If the intake volume decreases, ignition weakens, or the fuel injection reduces, the power will be insufficient, resulting in a jerking sensation.
I've been driving a Cadillac XTS for three years and have encountered severe transmission jerking issues. When shifting gears, it feels like being suddenly jerked, especially during frequent start-stop driving in the city or when going uphill. This isn't just uncomfortable driving—it may indicate internal problems: such as low transmission fluid level or aged fluid quality, where insufficient lubrication increases component friction; outdated control module software causing inaccurate shifting due to algorithmic errors; or sensor failures like position sensor malfunctions misleading transmission actions. Untreated, this accelerates wear and raises repair costs. I recommend first checking the dipstick for dirty or black fluid—address any leakage signs immediately. Regular maintenance should include having technicians read fault codes; software updates or fluid changes may improve performance. Safety first—jerking can lead to stalling or loss of control, so never push through it.
