Car jerks when i put it gear

what makes my car jerk when i put it in gear
Experienced mechanics share their insights in answering this question :
Assuming your car has an automatic transmission, it sounds like you may be low on transmission fluid. Automatic transmissions use transmission fluid that is pressurized to shift gears. When the transmission is low on fluid, this can cause delays in shifting or a bit of a jerking reaction due to the delay in building up the required hydraulic pressure to shift into gear. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
Old Or Incorrect Transmission Fluid

Using the wrong transmission fluid may result in some hard car jerks, especially at high speed.

This is usually caused by troubles with the vacuum, transmission fluid or a faulty sensor. The vacuum modulator valve helps older vehicles determine when to shift gears. There`s a hose that connects the valve with the intake through a hose.
What`s the secret to changing down gear smoothly? Maintain light pressure on the accelerator pedal as you press the clutch down, change gear and then clutch up gently (or the car will jerk). Using the accelerator will raise your engine speed to match your road speed, ultimately giving you a jerk free gear change.
It could be caused by a number of things from low transmission fluid to bad alignment. Several things might be the cause of this issue. Most of them will need to be diagnosed and fixed by a mechanic. Before taking your car to the mechanic, you can attempt to drain and refill your transmission fluid.
Lurching is caused by a mismatch between wheel and engine speed as the clutch engages. Release the clutch more slowly so their speed is synchronized gradually.
Avoid changing gears while the car is moving

The car will actually stop but you will end up wearing out your automatic transmission band. The transmission band is hard to access making its repair and replacement expensive and time-consuming.

1. At the top of all auto repair experts lists for causes of problematic transmissions is low transmission fluid. Usually caused by a leak somewhere in the system, low or contaminated fluid makes it nearly impossible for the transmission to automatically shift gears and run smoothly.
Typically, when your transmission begins to fail you may start to notice some form of difficulty when changing gears. Occasionally you may hear or feel a clunk noise when you shift gear. Another sign of a rough shifting is difficulty in accelerating to the speed for the gear that it is in.
This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
Low-quality transmission fluid – or driving without transmission fluid altogether – can cause a number of problems such as transmission failure, gear slipping, a hard time shifting, and a few more issues.
Rough Shifting or Jerking Transmission

Causes of rough shifting include: Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions.

When your car jerks, stumbles or stutters while driving, it usually means something is interfering with the proper distribution and transfer of power from your transmission. Another example is if you`re driving a manual transmission and haven`t gained the feel of shifting for your particular vehicle.
Automatic: Every 60,000 to 100,000 miles

If you drive manual, most manufacturers will recommend changing your transmission fluid every 30,000 to 60,000 miles. If you have automatic, you can typically boost that range up to 60,000 to 100,000 miles. There`s no harm in changing your fluid early.

This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears.
To answer your question, if you take your foot off the accelerator quickly while you are in first gear, the car will jerk in most cases because you transition from engine power to engine braking very quickly, and since first gear is so low, everything is amplified. The higher the RPM, the more pronounced the jerk.
This is a common problem when the throttle body sensor is faulty or dirty. There should be just 4 bolts holding this in place. I would recommend cleaning and checking this first before diving into transmission diagnosis. Also check the mass airflow sensor as this can also cause the same type of problem.
Shifting Before Your Car Has Stopped

If you switch between reverse, park, and drive too quickly, you run the risk of grinding your gears and causing serious damage to your car`s transmission.

There are 6 ways to improve automatic transmission performance and reliability. These are servicing the transmission, changing driving habits, driving with lower gears when loaded, maintaining engine performance, having proper alignment of tires, and having the correct tire size.
It is widely believed that switching the car to the neutral mode while driving will save fuel. However, it is dangerous to do so. Switching to neutral will reduce the control you have over the car. This can prove to be life-threatening in a risky situation.
Yes. While traveling at high speed, shifting from L to D could harm your car`s transmission. When driving, it is best to change from L to D slowly. If you were to move from a hilly road to a leveled road, you could slow down a little and shift from L to D without hesitation.
Low transmission fluid, clogged filters, and problems with the clutch can all contribute to transmission damage, so watch out for these issues.
Transmission fluid will become foamy if there is too much fluid. Excessive fluid prohibits proper lubrication and cooling and slows the rotating crankshaft, similar to the effect of running through water.

Car won’t go into gear. 2002 Audi A4 Quattro
ANSWER : Hi there – Your symptoms describe the behavior to expect when your clutch hydraulics go out (clutch master and clutch slave cylinders). Check your clutch fluid level – it may be low. If the fluid level is low, this usually means your clutch slave cylinder has worn out, not unusual with your mileage, and should be replaced. I recommend a malfunctioning clutch inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Car won’t move. I can start the car but when I put the shifter in 1st, 2nd, 3rd, ect. The car will not move.
ANSWER : The transaxle is not engaging internally to the axle shafts inside the transaxle or you have one or both axle shafts disengaged from the transaxle. The fact that the speedometer moves when gear is engaged and clutch is released shows the speed sensor in the transaxle is getting turned.

You will need to have the vehicle raised and the axles inspected for broke or stripped shafts. If the axles do not have anything visually wrong with them then hold one wheel and try to turn the other wheel while transaxle is in gear, with engine off, to see if the wheels are locked together. When you spin one wheel the other wheel should turn in the opposite direction. If it does not then the problem is in the transaxle differential gears and the transaxle would need to be removed and disassembled to find the broken internal components.

My car jerks when i put it on R/D and also there is a 2 seconds delay when i put it on reverse ( gear takes 2 seconds to engage )
ANSWER : The transmission has electronic controls as does the engine. It’s possible there is an electronic issue. A faulty transmission control module can give symptoms like you are experiencing. The brake light switch can also cause issues. On modern cars, the brake light switch also performs as a sensor for various systems like the ignition and anti-lock brake / stability control systems. Even if the check engine light is not on, there may be fault codes stored in the system. A certified technician can inspect the vehicle for shifting issues by scanning the system for faults. Fault codes will give the technician a direction to take in finding and repairing the exact cause.

Stays idling when I put it in gear, and the car doesn’t move. When forced into any gear without the clutch, the car does not shut off.
ANSWER : Hi there. The clutch may be worn and slipping causing the engine to stay running as the shifter is put into a gear selection. If the clutch was working, when put into gear and let off the clutch pedal, the vehicle will either move or stall out the engine. Check the slave cylinder and see if the return spring has broken off causing the clutch fork to stay engaged. Also the clutch adjuster cable could be out of adjustment or damaged. If the pedal and hydraulic assembly has no issues, then I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your clutch.

I was driving had my car on gear and lost acceleration. I pushed the clutch in and put on gear but only grind but won’t move?
ANSWER : If the clutch lever, on the transmission, is functioning something has mechanically failed in the clutch and/or the transmission. If the clutch failed, and you heard gears grinding, as you tried to shift the transmission, some damage may have been done to the transmission. Even if just the clutch has failed, the engine and transmission will have to be separated to find the cause of the failure and worn out or broken parts will likely have to be replaced . To request an inspection, the recommended service is clutch system diagnostic. If you request that diagnostic, the responding certified mechanic will evaluate what you have and let you know of your repair options and costs. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I got sound when I shift to 3rd gear and it’s get hard to put shift to second gear when car is in 3rd gear.
ANSWER : Hello. It sounds as though the synchronizers in the transmission, which are used to adjust transmission internal gear speed when upshifting or downshifting are possibly worn out or you are shifting a bit too fast. It is also possible that the clutch is not releasing fully when you press the clutch pedal. In some conditions, utilizing synthetic gear oil in the transmission can help the quality of gear shifting. If the clutch is not fully releasing an inspection of the clutch hydraulics is a good idea. I would recommend having an inspection of the hard shift completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost for repairs.
