Transmission Repair 101: What Is a Torque Converter?, West Haven, Connecticut

Torque converters are commonly heard during automatic transmission repair. If you’ve driven a car with a manual transmission system, you may be familiar with how it uses the clutch to send power from the engine to the drivetrain. This is not the case with an automatic model. Instead of a clutch, a torque converter is used.

What Is a Torque Converter?

A torque converter is a hydrodynamic device designed to transfer rotating power from an engine to a rotating driven load. It provides the same function as a clutch in a manual vehicle. Simply put, it allows the engine to keep running even if the wheels and gears in the transmission come to a stop. A torque converter is composed of two fans, a pump, a turbine, and an impeller. These components are sealed inside a housing that is bolted to the flywheel of the vehicle’s engine.

How Does a Torque Converter Work?

A torque converter uses a liquid medium—transmission fluid—to operate. As you turn on the engine, it generates power to spin the impeller, which will fling fluid toward the turbine to make it spin. The turbine is connected to the wheels through the transmission, so when it performs this movement, it causes the car to advance. When you step on the brake pedal, the turbine stops spinning, bringing the car to a stop. However, the impeller will still function, causing the engine to continue running.

Why Is a Torque Converter Important?

transmission repairThis system’s function is more than getting your vehicle to stop—it increases the amount of torque for your engine during acceleration or when hitting high revs. Modern converters can even multiply torque by two to three times. Failure of this system can lead to gear slipping, overheating, and shuddering. So at the earliest signs of a problem, bring your car to a mechanic for transmission repair right away.
