As an essential component in the transmission system of modern vehicles, the torque converter plays a vital role in transferring power from the engine to the transmission. However, when this complex system isn’t working properly, you can run into issues such as the infamous torque converter shudder. In this blog post, we will explore what the torque converter is, how it works, and the causes and symptoms of torque converter shudder.
What is a Torque Converter?
The torque converter is a fluid coupling that allows the engine to continue running even when the vehicle is stopped. The torque converter uses a hydraulic system to transmit power from the engine to the transmission. It is made up of three main components: the impeller, turbine, and stator.
When the engine is running, the impeller, which is connected to the engine, pumps fluid into the turbine. The turbine, which is connected to the transmission, then receives the fluid and begins to rotate. The stator, which is located in the middle of the impeller and turbine, redirects the fluid flow to increase the torque output of the engine.
How Does a Torque Converter Work?
As mentioned above, the torque converter works by using a hydraulic system to transfer power from the engine to the transmission. This system consists of a pump, a turbine, and a stator.
The pump is driven by the engine and draws fluid into the torque converter. The fluid is then directed to the turbine, which is connected to the transmission. The turbine uses the fluid’s energy to turn the transmission’s input shaft, which provides power to the wheels. The stator redirects the fluid flow to increase torque output.
Causes of Torque Converter Shudder
A torque converter shudder occurs when the torque converter fails to transfer power smoothly. This can happen due to a variety of reasons, including:
Worn Torque Converter Clutch
The torque converter clutch is responsible for connecting and disconnecting the engine from the transmission. Over time, the friction material on the torque converter clutch can wear out, causing the clutch to slip or engage improperly. This can lead to torque converter shudder, especially during acceleration.
Contaminated Transmission Fluid
The transmission fluid in an automatic transmission is essential for lubricating and cooling the components inside. However, over time, the fluid can become contaminated with debris, dirt, and metal particles. Contaminated fluid can interfere with the operation of the torque converter, causing it to shudder.
Damaged Torque Converter
A damaged torque converter can cause torque converter shudder. Damage to the torque converter can occur due to overheating, wear, or manufacturing defects. For example, if the impeller, turbine, or stator blades are damaged or bent, the fluid flow inside the torque converter can become disrupted, leading to shuddering.
Symptoms of Torque Converter Shudder
When torque converter shudder occurs, it can manifest in a few different ways. Some of the most common symptoms of torque converter shudder include:
Vibrations
One of the most noticeable symptoms of torque converter shudder is vibrations or shaking while driving. These vibrations can be felt through the steering wheel, floorboard, or seat of the vehicle. The severity of the vibrations may vary depending on the extent of the shudder and the speed of the vehicle.
Rough Shifting
Torque converter shudder can also cause rough shifting between gears. You may notice that your vehicle jerks or hesitates during acceleration or deceleration. In severe cases, the transmission may shift erratically, making it difficult to maintain a consistent speed.
Slipping Transmission
If the torque converter is slipping, you may experience a delay in acceleration or a loss of power. You may notice that your vehicle struggles to maintain speed, especially when going uphill or towing a load. In some cases, the transmission may slip out of gear entirely, leaving you stranded on the side of the road.
How to Solve Torque Converter Shudder?
Fixing the torque converter shudder comes down to two approaches — temporary and permanent. If you’re looking for a permanent fix, you’ll most likely deal with one of the following.
Flush and Replace Transmission Fluid
Dirty or contaminated transmission fluid needs to be flushed and replaced with fresh fluid. A mechanic will drain the old fluid from the transmission, including the torque converter, and replace it with new fluid. They may also add a transmission fluid conditioner to help prevent future shudder issues. Find a wide selection of high quality transmission fluids at our store!
Replace Torque Converter Clutch
If the torque converter clutch is worn out, it needs to be replaced. This involves removing the transmission from the vehicle and disassembling it to gain access to the torque converter. The old clutch is then removed, and a new clutch is installed in its place. The transmission is then reassembled and reinstalled in the vehicle.
Repair or Replace Damaged Torque Converter
A damaged torque converter is a common cause of torque converter shudder. In that case, you’ll need to repair or replace the converter. This involves removing the transmission from the vehicle and disassembling it to gain access to the torque converter.
Depending on the extent of the damage, the torque converter may be repaired or replaced with a new one. The transmission is then reassembled and reinstalled in the vehicle.
