FAQs About The Torque Converter

Torque converters are key components of transmissions. How often do they require repair? Are they expensive? And just what the heck are they? Here are some frequently asked questions about torque converters.

What Is A Torque Converter?

In a manual transmission, the engine is connected to the transmission via the clutch. The clutch is pretty important, because without it, you couldn’t possibly stop your vehicle without stalling your engine. But automatic transmissions do not have a clutch. Automatic transmissions utilize a torque converter. The torque converter plays a similar role to the manual transmission clutch.

The torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission. When an engine is turning slowly, like when you’re idling, for example, only a small amount of torque passes through the torque converter. As a result, you needn’t press hard on the brake pedal to keep the automobile stationary. When the light turns green and you’re done idling, you press on the gas pedal. But you have to press harder to get going than you do to accelerate when you’re already in motion because engine is just speeding up and pumping more fluid in the torque converter, resulting in more torque being transmitted to the wheels.

How Much Torque Passes Through The Converter?

Modern torque converters can multiply the torque of the engine by two or even three times. Maximum multiplication only occurs when the engine is turning much faster than the transmission.

Are Torque Converters More Efficient Than Clutches?

It’s not exactly fair to compare the two directly, but no, they are not as efficient. Ultimately this is because automatic transmissions are not as efficient as manual transmissions. The goal of an automatic transmission is to maximize the ease of use. At high speeds, the engine and torque converter almost move at the same speed. However, for efficiency, it would be ideal for them to move at exactly the same pace.

What Is A Lockup Clutch?

Some torque converters have a lockup clutch to make up some ground on the efficiency front. When the two halves of the torque converter get up to speed, the lockup clutch locks them together, thus eliminating slippage and improving efficiency.

What Are Some Symptoms Of A Bad Torque Converter?

A problematic torque converter can manifest in a number of ways including slipping, overheating, unusual noises, and contaminating the transmission fluid.

Do Torque Converters Need To Be Replaced Often?

If you take care of your transmission, no. But when there are transmission problems, torque converters are some of the more common items to be replaced. To learn more about torque converters, please contact Mister Transmission.

Brought my truck to this location after discussing the symptoms of my faulty clutch.Dealt with two other garages previously who attempted to overcharge for work not needed.The manager here fixed the problem at a fraction that the other garages quoted me for.Truck drives perfect and he even threw in a free transmission oil change for some unforeseen delay.Honest and competitive. Thanks Mr Transmission.

Always above and beyond!Mostly my car has gone in for basic maintenance, but recently I had a hitch installed on my car. In the process of having this done it was noticed I had a sensor malfunctioning. NO PRESSURE what so ever to have this fixed at the same time. I was told the risks and given a choice. I chose to fix it as my car was in anyway, but I loved having the choice with no judgement or pressure. Pricing was fair, and definitely less than I was expecting. I didn't feel my lack of car knowledge as a female was an issue here at all. I was made to feel informed and involved. I recommend this shop to all of my friends ☺️
