Symptoms of a bad torque converter

There are only a few people who know that torque converter is an essential element of your car that is responsible for passing on a limited amount of fluid to the automatic transmission. It is also responsible for providing sufficient power to your engine so that it may continue running while at a complete stop.

You may experience erratic behavior of your car, such as slipping and shuddering, if any problem occurs with the torque converter. Figuring out the exact reason behind the problems of the torque converter is a tedious task. The malfunction can be caused due to many potential reasons, and it might not be a fault of the torque converter.

So, here we’re going to talk about a few symptoms of bad torque converter so that you may find a proper solution for the problem at the right time. Here you’ll find more information about a bad torque converter.


Symptoms of a bad torque converter include dirty fluid, shuddering, high stall speeds, slipping, overheating, or strange noises. Be patient before making any decision because most of the times the cause of the problem may not be the torque converter. So, make sure that you check the transmission first before coming to a conclusion.


If your temperature gauge is overheating, then it could be a sign that the there is some problem with the torque converter. The transmission will overheat due to a drop in a fluid, therefore, one of the most common signs of torque converter issues is the overheating. Overheating can also be a sign of malfunctioning solenoid or low fluid levels, so make sure to check that first.


Another most common sign of torque converter problems is the shuddering at the speed of 30-45 MPH. It can clearly be noticed when running over the bumps or rough road. You should get your transmission checked immediately once you experience the shuddering for the first time.

Transmission slipping

The gear might start slipping if the transmission isn’t receiving enough fluid. And due to this problem, you’ll often experience a loss of acceleration. Your car’s fuel economy might also start dropping suddenly. If you experience any slipping, you must check the fluid first because ineffective fluid can also be the culprit.

Contaminants in fluid

If you find a huge amount of black material in the fluid, it means that your torque converter clutches are malfunctioned.

Strange sounds

Some unnecessary sounds may also be an indication of a bad torque converter such as clicking or a revving noise.

Increase stall speed

The stall speeds will be higher than normal due to the bad torque converter because it’ll take longer for the transmission to engage the engine. You can diagnose any torque converter problems by doing a stall speed test but before that, you should clearly know the stall speed specifications of your engine and the torque converter first.

These are the basic symptoms of a bad torque converter that can easily be diagnosed. So, make sure you check these problems before coming to a conclusion. Click here and learn more about a bad torque converter.
