What Are The Indications Of A Bad Torque Converter?

The torque converter is an integral part of the transmission. However, torque converters can also be a problem area. Is there something wrong with yours? What are the symptoms of a bad torque converter?

What Is The Torque Converter?

Before we get into symptoms and other matters, let’s make sure everybody is on the same page first. What exactly is the torque converter? The torque converter is a form of fluid coupling which transfers rotating power from the engine, to a rotating driven load, i.e., it allows power to flow from the engine to the wheels. But more than that, a torque converter can multiply torque when the rotational speed is very low, effectively providing the equivalent of a reduction gear. This is how the torque converter goes beyond simple fluid coupling, which can match rotational speed but cannot multiply torque. Your torque converter might also have a “lockup” mechanism that binds the engine to the transmission when their speeds are roughly equal, avoiding slippage and reducing inefficiency.

That’s What The Torque Converter Does When It’s Working. What Does It Do When It Isn’t?

The torque converter is one of the more commonly replaced components of transmissions. That means torque converters tend to wear down and receive damage more often than other parts of the transmission. Is your torque converter in bad shape? How can you tell? What are the symptoms of a bad torque converter? Here are four of them:

1.    Odd sounds are a symptom of a bad torque converter
Transmissions, and your vehicle in general, shouldn’t be very loud. And the noises it makes, it should make pretty regularly. When you begin to hear unusual noises, you should take notice. Rattling is one sound you want to be aware of. If you hear odd rattling sounds when you accelerate, this might be a symptom of a bad torque converter. The same can be true of whirring noises.

2.    Shakiness is a symptom of a bad torque converter.
If those rattling noises are accompanied by shakiness and bad vibrations, your torque converter is likely in trouble. If it feels like you’re driving on a bumpy country road when you are not, bring your vehicle in as soon as possible.

3.    Difficulty shifting is a symptom of a bad torque converter.
You want to be able to shift gears smoothly. A bad torque converter will not allow for that.

4.    Slipping out of gear is a symptom of a bad torque converter.
Hard shifts are bad but the opposite is also bad. You don’t want to be slipping out of one gear into another.

Vanessa Orchard
Mandy's customer service was second to none. Not only did he make sure the work they could do on our truck got done in a timely manner, but also made arrangements for other services to be completed that are outside their scope. PLUS, he took care of getting our truck there and back! Like Mandy said, we hope we don't need to see him for that truck again, but if we need transmission services for any of our other vehicles, we'll be back! Thank you for your great customer service Mandy!

Akash Kachchhi
Highly recommended! I wasn't sure where to take my car for a transmission repair. Had quotes from other shops, which were all around the same, but no one was offering warranty on their work more than one year even after spending so much money. Only Mr. Mandeep offered me three years warranty, which makes me assured to go forward with the repair. Mr. Wes is really knowledgeable technician and he did a fantastic job, car works like new! Incredible staff that go above and beyond for their customers. Their customer service is great and the car was done on time.

I took the car in because I had issues with my transmission, not only did they fix it but they fixed my lower control arm and adjusted my brakes, these are problems that were missed on the safety, Dan also dealt with my warranty company as well as made sure I had the financing to get my car back with no out of pocket funds, they worked late making sure I had the car on the day they said, thank you Dan and Bob for all your hard work.
