Car Jerks When Shifting From Park to Drive – Reasons and Solutions
It seems that several people have reported experiencing a jerk when shifting their cars from Park to Drive or Reverse, as well as when shifting from Drive or Reverse to Neutral.
Some people have reported that the issue was resolved after a software update, while others have suggested that it could be related to the transmission mount, solenoids, throttle body adaptation, or the mechatronics unit. It’s recommended to have a mechanic inspect the issue to determine the root cause.
Reasons for Car Jerking
Engine Problems
- Engine misfiring: Engine misfiring occurs when one or more of the cylinders in the engine fail to ignite the fuel-air mixture as intended. This can cause a loss of power and a jerking sensation when shifting from park to drive.
- Engine oil level is low: A low engine oil level can cause friction between the engine components, leading to a jerking feeling when shifting from park to drive. This is because the lack of oil leads to the parts rubbing against each other and causing a jerking sensation.
Transmission Problems
- Low transmission fluid level: The transmission fluid acts as a lubricant and coolant for the transmission components. If the fluid level is low, it can lead to friction between the components and result in a jerky shifting sensation.
- Worn or damaged transmission components: Over time, the components in the transmission can wear out or become damaged. This can lead to a jerky shifting sensation, especially when shifting from park to drive.
Drivetrain Problems
- Worn or damaged drive axles or CV joints: The drive axles and CV joints transfer power from the engine to the wheels. If these components are worn or damaged, it can cause a jerking sensation when shifting from park to drive.
- Damaged or worn out differential: The differential is responsible for distributing power to the wheels. If the differential is damaged or worn out, it can cause a jerking sensation when shifting from park to drive.
Car jerking when shifting from park to drive can be caused by a variety of factors, including engine problems, transmission problems, and drivetrain problems. It’s important to have your car inspected by a professional mechanic to determine the cause of the problem and get it fixed as soon as possible.
Solutions
Engine Problems
- Engine misfiring: Engine misfiring can cause jerking when shifting from park to drive. This can be due to a number of issues such as a faulty spark plug, a clogged fuel injector, or a malfunctioning ignition system. To fix the problem, a mechanic will need to diagnose the cause of the misfire and repair or replace the faulty component.
- Engine oil level: If the engine oil level is low, this can cause jerking when shifting from park to drive. Engine oil is essential for lubricating the engine components and preventing wear and tear. If the oil level is too low, the engine can become damaged, leading to jerking and other performance issues. To fix the problem, the oil level needs to be checked and topped off as needed.
Transmission Problems
- Low transmission fluid level: Low transmission fluid levels can cause jerking when shifting from park to drive. The fluid is necessary for the proper operation of the transmission and if it’s too low, the transmission can become damaged, leading to jerking and other performance issues. To fix the problem, the fluid level needs to be checked and topped off as needed.
- Worn or damaged transmission components: If the transmission components are worn or damaged, this can cause jerking when shifting from park to drive. This can be due to normal wear and tear over time, or damage from an accident or other issue. To fix the problem, the worn or damaged components need to be replaced by a qualified mechanic.
Drivetrain Problems
- Worn or damaged drive axles or CV joints: Drive axles and CV joints are responsible for transferring power from the transmission to the wheels. If these components are worn or damaged, this can cause jerking when shifting from park to drive. To fix the problem, the worn or damaged components need to be replaced by a qualified mechanic.
- Damaged or worn out differential: The differential is responsible for dividing torque between the wheels and allowing them to rotate at different speeds. If the differential is damaged or worn out, this can cause jerking when shifting from park to drive. To fix the problem, the damaged or worn out differential needs to be replaced by a qualified mechanic.
Prevention
Regular maintenance is one of the key ways to prevent car jerking when shifting from park to drive. This includes regularly checking the engine oil level and topping it off if necessary, as well as checking the transmission fluid level and topping it off as needed.
By doing this, you can ensure that your engine and transmission are functioning properly and that there are no issues that could cause your car to jerk. In addition to regular maintenance, it is important to pay attention to warning signs that could indicate a problem.
This includes an engine misfire, which is when the engine misses a few beats and doesn’t fire properly. Another warning sign is unusual noises, such as clunking or grinding sounds, which could indicate a problem with the transmission or drivetrain.
If you notice any of these warning signs, it is important to get your car inspected by a professional to determine the cause of the issue and make any necessary repairs.
Overall, by following a regular maintenance schedule and paying attention to warning signs, you can help prevent car jerking when shifting from park to drive and ensure that your car is functioning properly.

FAQs
The most common causes of a car jerking when shifting from park to drive are engine problems, transmission problems, and drivetrain problems. Engine misfiring, low engine oil level, low transmission fluid level, worn or damaged transmission components, worn or damaged drive axles or CV joints, and damaged or worn out differential can all contribute to a jerking sensation when shifting gears.
Yes, low transmission fluid can cause a car to jerk when shifting gears. This is because the transmission relies on a certain level of fluid to function properly and smoothly. If the fluid level is too low, the transmission may struggle to shift gears, which can result in a jerking sensation.
Signs of a worn out differential include unusual noises, such as whining or growling, as well as vibrations felt through the car’s body or steering wheel. Additionally, if you notice a loss of power or acceleration when driving, it may indicate a problem with the differential.
It is recommended to check your engine oil level at least once a month, or more often if you drive frequently or under extreme conditions. Checking the oil level regularly can help prevent engine problems and ensure that your car runs smoothly.
It is generally not safe to drive a car that is jerking or experiencing other unusual sensations. Driving a car with these symptoms can cause further damage to the engine, transmission, or drivetrain and may result in costly repairs. It is recommended to have the car inspected by a professional as soon as possible to identify and address the problem.
Conclusion
A car jerking when shifting from park to drive can be caused by a number of factors, including engine problems, transmission problems, and drivetrain problems. To solve the issue, it is important to identify the root cause and take the necessary steps to fix it.
Regular maintenance and paying attention to warning signs can also help prevent car jerks when shifting from park to drive. By addressing the issue promptly, you can keep your car running smoothly and avoid any potential hazards on the road.
