Transmission Jerks When Shifting? Here are the Possible Causes

Does your vehicle transmission lunge when shifting gears? There are many reasons why a transmission gets this kind of issue. If your car is new and you notice the transmission jerking, then it’s probably due to a driver’s error. In general, a transmission malfunction usually occurs when the fluid level is low, there is scarcity in the fluid for frictional properties, or there is a degradation of cold temperature fluidity. If you experience the problem of transmission shifting hard, then there can be other mechanical faults as well. The issue of transmission jerks when shifting should not be ignored. This can lead to serious issues while driving. Ignoring transmission bucking can cause damage to other performance parts of the car as well, such as the engine.

Problems That Lead to Transmission Jerks When Shifting

Does your transmission jolt when shifting gears? There can be many probable reasons that result in the jerking of transmission while shifting gears.

Clutch Malfunctioning

A clutch can that cannot set itself free from the flywheel often halts the process of shifting gears. It is also known as clutch dragging. In this, the clutch continuously keeps spinning along with the engine, making an annoying sound that also causes wear and tear to other transmission parts.

The common sign to detect is a dragging sound every time you try to shift the gear. Consider getting the problem checked by a professional mechanic to ensure smooth driving.

Defect in Synchronization Ring

The synchronization ring is part of the transmission that is aligned with the gear and the clutch. Its main function is to cone the gear either to slow it or pace it up. This ensures smooth shifts of the gear.

However, if the problem still continues with the clutch, it can affect the functioning of the ring. This results in transmission jerks when shifting gears. Therefore, it is better to get the problem of the clutch checked.

Because ring replacement is often costly and time-consuming. Also. if the ring is not functioning properly, it also degrades the functioning of the transmission completely.

Gear Lever Wire Problem

Sudden car jerks while shifting gears can be due to a defect in the gear lever wire. It acts as an acceleration link. It can also result in the car stopping mid-way while shifting gears.

Therefore, it is better to get the gear lever wire checked. If the wire is loosely set up, it can be altered accordingly. However, in most cases, the lever wire is subject to replacement.

Therefore, it is better to get it checked by a professional mechanic, as the wire is quite significant to the overall functioning of the system.

Worn-Out or Damaged Gearbox Parts

The gearbox is often damaged by improper driving style. If the clutch is not completely pressed while shifting gears or the gear is not properly in, shift to another gear. In both cases, there is a definite possibility that the gearbox and the transmission are meant to get damaged.

This can also result in acceleration not working at all. It is better to ensure smooth gear shifts in the correct manner. Otherwise, it will continuously degrade the overall transmission performance.

If you are experiencing such a problem, get your vehicle inspected by a nearby Spare Part Shop. Such problems ignored for a long time are often costly to fix.

Weak Mounting of the Gearbox

Does the transmission jerk when shifting from reverse to drive? A degraded or weak gearbox mounting can result in harsh jerks while shifting gears. You can detect this problem if the gear automatically changes while speeding up.

Also, if there is a constant sound of thumping or knocking from the transmission, you probably have this issue.

Consider getting the problem fixed by a professional mechanic. Neglecting the problem will result in harm to other parts of the transmission and will significantly cost more.

Can Low Transmission Fluid Cause Jerking While Shifting Gears?

Transmission fluid is an integral part of the transmission as it ensures the optimum functioning of the gearbox. With low transmission fluid levels, friction increases while shifting gears.

Therefore, the gear shifts are hard and rigid. Maintaining a proper level of transmission fluid is essential. The fluid also helps to keep the temperature normal for better transmission output.

If you are looking for an aftermarket transmission for your vehicle. You can quickly get it delivered to your doorstep from “used transmissions for sale.”


What causes a transmission to jerk while shifting gears?

Many reasons can lead to transmission jerks when shifting gears. Low fluid levels, worn-out gearbox, faulty synchronization ring, issues with the gear lever wire, and malfunctioning of the clutch are the common reasons for bad gear shifting experience.

How can I stop my car from jerking while shifting gears?

It is important to shift the gears accurately. Always push down the clutch entirely and not halfway while shifting gears. Do a firm but systematic gear shift. Do not shift the gears abruptly. However, if there are mechanical problems with the transmission, there is significantly less that you can do apart from seeking help from a professional mechanic.

Does changing the transmission fluid help in fixing the jerks while shifting gears?

There is a possibility that the transmission fluid in your vehicle is at a low level. In such cases, changing the transmission fluid is the best thing you can do. However, if the problem persists, then there is no issue with the transmission fluid. Get your vehicle checked by a professional mechanic to tackle the problem.

How to know that the transmission fluid is at a low level?

If your vehicle has low levels of transmission fluid, then it will make a gurgling sound. A lot of people forget to check the transmission fluid regularly. This often results in bad performance of the transmission. In the long run, Neglecting the problem can result in transmission jerks when shifting gears.

What to do if the automatic transmission jerks when shifting gears?

Consider changing the transmission fluid of your vehicle if these problems happen. Low fluid levels are the common reason for such cases in automatic transmission.
