What Causes Transmission Shudder and How to Resolve It

all about transmission shudder

Transmission shudder, also known as torque converter shudder, is a vibration or shaking that occurs when the transmission shifts gears, particularly during lockup in the torque converter. It’s often felt during acceleration and can be intermittent. Let’s go through the common causes and fixes of shuddering transmission. 

Here are the common causes of transmission shudder. 

Shuddering transmission is also caused by dirty transmission fluid. With time, the car’s fluid can become contaminated with tiny metal particles, thickening the oil and preventing proper contact between the transmission plates during engagement.

To prevent this, it’s crucial to follow the manufacturer’s recommended service intervals and change transmission fluid regularly. Unfortunately, many drivers neglect routine maintenance and only service their vehicle when problems arise. This neglect allows the transmission fluid to become dirty, leading to issues like shuddering.

Additionally, many drivers are unaware of how or when to change their transmission fluid. Understanding the importance of regular transmission fluid changes and seeking professional assistance can ensure a smoother driving experience and help prevent transmission problems in the future. Here are the common symptoms of excessive car transmission fluid. Moreover, using the wrong type of transmission fluid can also cause shudders. 

When transmission fluid levels are too low, the internal parts may not receive adequate lubrication, leading to the accumulation of metal shavings and debris in the fluid. These particles can circulate within the transmission, causing premature wear on critical components such as gears and clutch plates.

Low fluid levels can also cause shuddering transmission. It hinders smooth gear shifting, resulting in jerky and rough transitions, causing shuddering while driving. Driving on low transmission fluids is also among common habits that damage car transmission.

To prevent these issues, it’s essential to regularly check and maintain the correct transmission fluid levels. If you notice the fluid is low, adding more can help avoid further damage and ensure smoother operation. Here is how to check transmission fluid levels while the engine is on. 

The torque converter is a crucial component of a vehicle’s transmission system, responsible for transferring power from the engine to enable movement. In automatic gearboxes, it serves as the connection between the engine and the transmission.

The torque converter consists of five essential parts: the impeller, turbine, fluid, clutch and stator. These components work together to transfer power efficiently. When the engine spins the impeller, it pushes the fluid, which in turn rotates the turbine. This process allows the engine’s power to flow smoothly through the transmission, facilitating seamless gear shifts and ensuring optimal vehicle performance.

A faulty torque converter can lead to transmission shudder, gear slipping and overheating. If you notice these symptoms, it is important to replace the torque converter to prevent further damage and maintain smooth gear shifting and overall vehicle performance.

Modern vehicles use sophisticated electronic control systems to manage the operation of the transmission. These systems rely on a network of sensors, actuators and control units to ensure smooth and efficient gear changes. 

When these electronic components malfunction, they can cause transmission shuddering. Faulty transmission control modules, malfunctioning sensors, wiring issues, solenoid problems (transmission solenoids control the flow of transmission fluid within the transmission) or software problems can cause transmission shudders.

Fixing transmission shudder in cars involves addressing the underlying causes, which can range from fluid issues to electronic control problems. Here are detailed fixes for common causes of transmission shudder:

For fixing dirty transmission fluid, drain and replace the old transmission fluid with fresh, manufacturer-recommended fluid. In some cases, a transmission flush may be necessary to completely clean out the system. It’s important to follow the vehicle manufacturer’s specifications for fluid type and change intervals.

To fix shudder problems caused by low levels of transmission fluid, check and maintain the fluid levels regularly. If the fluid is low, add the appropriate type and amount of transmission fluid. Check for leaks that might be causing the fluid levels to drop and repair any leaks found. Here is how to identify fuel leaks by colour and spot leaks.

In case of a bad torque converter, replace the worn or faulty torque converter with a new or rebuilt unit. Ensure proper installation and compatibility with your vehicle’s transmission system. A professional mechanic can diagnose and perform this replacement.

For electronic problems, the following transmission shudder fixes are essential:

For fixing this problem, diagnose the solenoids using diagnostic tools. Replace any solenoids that are not functioning properly. Solenoids control the flow of transmission fluid. The malfunctioning ones can cause shuddering.

Preventing transmission shudder can be done with regular maintenance, using the right fluid, monitoring fluid levels and addressing transmission issues promptly.

A bad torque converter and transmission shudder are related but not the same problem. The torque converter is a part of automatic transmissions. It transfers power from the engine to the transmission. It also allows the engine to keep running while the vehicle is stationary and helps multiply engine torque. On the other hand, transmission shudder, sometimes called torque converter shudder, is a vibration or shaking that happens when the transmission shifts gears, particularly during torque converter lockup.

Drain and replace the old fluid with fresh, manufacturer-recommended transmission fluid. A transmission flush may also be necessary.

Yes, low transmission fluid levels can lead to inadequate lubrication and cause shuddering.

Those were the typical issues causing transmission shudder and how to fix them. It’s crucial to regularly maintain your car to prevent technical issues like shuddering. Additionally, if you detect any signs of transmission problems such as odd noises, gear slipping, or shuddering, it’s best to have your vehicle checked by a professional promptly. 

By pinpointing and resolving the root causes of transmission shudder, you can ensure your vehicle operates smoothly and prolong the lifespan of its transmission. Besides, those looking to buy a vehicle can go through these used cars for sale in the UAE.
