When a BMW stops, it often jerks, which indicates a transmission issue. Some BMW transmissions have a ZF mechatronics component that is infamous for downshifting from second to first gear. In the valve body, worn or damaged solenoids or solenoid springs are the most frequent culprits. It is possible to replace this component on your own, but a professional repair could cost up to $3,500.
It is possible for owners experienced in error code interpretation and BMW transmission repair to fix this problem on their BMW. The home improvement project is classed as “Hard,” can cost up to $2,000, and takes two hours to complete.
Fortunately, there are a number of other transmission-related problems that your BMW could be experiencing, many of which are easier and less expensive to fix. Let’s examine the most common BMW ZF transmission issues and possible solutions.
The BMW being stuck in park is another frequent problem mentioned by BMW owners; if this is the case with your vehicle, read this article!

COMMON DISCLAIMER: Yes, I did attempt to search. Nothing definite. Just be polite.
I recently bought a 2006 BMW 750LI. adore it There are occasional little problems, like an out-of-focus angel eye (which was remedied! ), but there is one on which my mechanic and I differ. I’m not a mechanic, but this is the situation:
Car operates flawlessly. shifts flawlessly. Triptonic is the ideal. shifts down perfectly. However, I experience a jerk while I am coming to a halt. The wheel makes neither an odd noise nor feels an odd sensation. Simply put, the automobile doesn’t want me to stop smoothly. The automobile will brake normally if I am moving at any speed and apply “regular” braking pressure as I stop. No jerking or shaking. When you reach the final 5 mph to 0 mph stop, there will be a jerk (at stop), followed by an instant release, which will cause the car to briefly move before coming to a complete stop. The jerk IS a premature halt; it doesn’t happen when the car is moving. It appears as though you are applying the brakes as usual and just before stopping, you consciously hit them harder to come to a swift stop (the “jerk”). When the car finally stops, it does so with a little more rocking than you might anticipate from a hard stop. When braking, it almost looks as though something is loose and giving.
I can lessen the jerk at the end if I deliberately strive to come to a smooth and gradual halt, but I can’t achieve the truly smooth stop that anyone would expect.
The automobile will still come to a premature stop if I apply more force to the brakes toward the end, but I will be able to stop it from making a tiny forward movement.
As I even completed this task in Neutral and it still occurred, I do not believe that this is a tranny issue.
My mechanic initially believed it to be a typical issue he encounters with some components of the front suspension (thrust bars or something?). He later informed me that the rack required replacement. I find it very difficult to believe that. Again, I am not a mechanic, but when I noticed a change in the wheel, such as a problem with the power steering and an inability to make precise adjustments, I had the rack in my old Mercedes S500 changed. I experienced it. In my 750, I have no sensation in the wheel.
I’ve looked through the forums and found references to this for other models, but not particularly the E66. I’ve read that the tranny or some bushings might be to blame. Before I spend more than $2000 on a new rack, I thought I would get some advice from the locals.
HELP. I would be more than willing to upload a video to YouTube from both the exterior and the interior cabin experience.
Why does my car continue to jolt as I brake?
The most typical reason for a car to operate erratically is worn tires, but if the vibration appears to coincide with depressing the brake pedal, it may indicate that your brake components need to be replaced.
It’s one of the most frequent problems a car can experience. Your steering wheel shakes back and forth when you apply the brake. So what is it that makes a car tremble as it brakes?
Your wheels may not be balanced, which could be the cause of your wobbling steering wheel. As the shaking is transferred to your steering wheel at high speeds, this symptom may become worse.
Depending on the driving conditions, a car with warped or out-of-balance brake rotors may jerk to a stop or vibrate violently.
The area of the rotor under the brake pads may accumulate dirt and debris if the brake pads are worn or clogged with debris, which will cause the vehicle to pulse while applying the brakes.
Pressing the brake pads against the rotor is the function of the braking calipers. It can cause the steering wheel to vibrate if it doesn’t properly push the pads. Your brake calipers may malfunction if dust accumulation, wear, or corrosion prevent them from balancing the force between the two pads.
First, check to see if there are any worn components in any of your tires. It’s time to replace your tires if they are severely worn. Take your automobile to a reputable repair shop to have the worn brake rotors and pads changed or serviced if your car is shaking as a result. Try to drive smoothly, and have your car periodically inspected by a reputable mechanic to prevent brake component wear and tear. This includes not abruptly depressing the brake or accelerating too much.
Why jerks my car as it slows down?
Your automobile makes a sound as it jerks, but the sensation is more noticeable. Usually, you experience quick tremors. It resembles your car gasping for breath.
Most frequently, an imbalance between the air and fuel coming to the engine is what causes a car to jolt while slowing down. It is crucial to troubleshoot because there are numerous parts and components that could be the source of this imbalance.
Your automobile may potentially jolt due to an issue with your brakes or tires. It’s possible that your gasoline filter is clogged.
Impurities are kept out of your engine by the filter, but when it is unclean, it is unable to do so. They eventually end up in your engine, where they could cause an abrupt jerk.
The mass airflow sensor checks if the amount of fuel and air entering the engine is balanced. If the sensor malfunctions, the two become unbalanced and your automobile may either receive too much or too little fuel.
Additionally, this can cause your car to jerk. Your automobile can jerk if your throttle position sensor is malfunctioning. The sensor controls the throttle position, and if it malfunctions, your automobile may jerk.
Last but not least, a faulty or broken tire might make your car jerk and pull.
Simple objects like metal, glass, or nails can harm your tire sufficiently to cause alignment issues.
Is jerking in an automobile bad?
You shouldn’t dismiss the problem if you notice that your automobile shakes as you accelerate. If you don’t fix a jerking car, your vehicle may experience further issues in the future. One of the most frequent causes of jerky acceleration is dirty fuel injectors.
How is a jerky car fixed?
Fuel injector clogging is a relatively frequent problem that can lead to a variety of auto issues. Your automobile may jerk if a clogged fuel injector prevents it from getting the fuel it needs to accelerate. The injectors may not be supplying enough gasoline if you hear the engine of your car stuttering.
You should routinely clean the injectors to resolve this. The issue of the automobile jerking could be resolved by using a fuel injector cleaning solution. Injectors may need to be removed, cleaned, or replaced by a mechanic if the obstruction is too bad.
Is it secure to operate a jerky vehicle?
When an automobile shakes while accelerating at high speeds, airflow problems are frequently to blame. At high speeds, your car needs more air to be injected into the engine. Your car will have trouble providing the right amount of air to the engine if there is a problem with the intake system. Your engine won’t function properly since the combustion process will be hampered. It results in misfires and jerking when your automobile tries to accelerate.
If you experience this, you should examine your air intake system and mass air flow sensor, and if necessary, get it replaced. However, this could also be caused by other issues.
In any event, if you’re experiencing this, it would be smart to examine your car right away. Driving a car that jerks when accelerating at high speeds can be risky since you risk losing control of the speed of your vehicle. If the drivers behind you are unaware, your car may lose speed quickly and you may be rear-ended.
Can a car jerk because of the transmission?
Transmissions that are in good working order maintain your ride comfortable when shifting gears. Automatic transmissions that jerk, tremble, or shift harshly could indicate that the fluid in the transmission needs to be changed or is low. Abnormal gear shifts in a manual transmission car could point to worn clutches, damaged gear synchros, or other, more serious problems.
What does it indicate when an automobile jerks?
When you press the gas pedal, your automobile may feel like it is jerking, surging, bucking, or stuttering. This is usually because there is not enough fuel, air, or spark to complete the combustion process.
There are other factors, though, that could be the reason. Before the issue worsens and becomes more expensive to resolve, you want to identify and address it as quickly as you can.
Does jerking result from low brake fluid?
I’m a little anxious about my brakes. My car, which I don’t know much about, jerks every time I use the brakes. Do I need to worry? Why would hitting the brakes cause my car to jerk?
In less than two minutes, find out if your auto insurance is being overcharged.
Uh oh! It doesn’t sound nice, that! I’m sorry to hear that your brakes aren’t working properly. Jerking while braking can be brought on by a number of problems, including worn brake pads or rotors as well as bad ABS wiring.
Brake problems should be taken seriously, therefore you should get your car serviced as soon as possible. Here are some typical causes of jerky braking that the mechanic will check for when you bring your car in:
