The Basics of Torque Converters
A torque converter is a device that allows an engine to spin independently of the transmission, while still delivering power to the wheels. It consists of three main parts: the impeller, the turbine, and the stator. As the impeller spins, it creates a fluid flow that drives the turbine, which in turn drives the transmission. The stator helps to redirect the fluid flow, improving efficiency and reducing heat.
Say Hello to Automatic Transmission
Automatic transmissions became popular in the 1950s and 60s, as cars became more affordable and more people began driving. Unlike manual transmissions, which require the driver to shift gears manually, automatic transmissions use hydraulic pressure to shift gears automatically, making driving easier and more comfortable.

Without a torque converter, an automatic transmission would be jerky and inefficient, making it difficult to drive.
Understanding Torque Converter Operation
When the engine is running, the impeller spins, creating a fluid flow that drives the turbine. As the car accelerates, the impeller and turbine spin faster, creating more fluid flow and more torque. The stator helps to redirect the fluid flow, improving efficiency and reducing heat. When the car comes to a stop, the stator locks in place, preventing the fluid from spinning, and allowing the engine to continue running without moving the car.
The Importance of Fluid Coupling
The fluid inside the torque converter acts as a coupling, connecting the engine to the transmission and allowing them to spin at different speeds. This fluid coupling helps to reduce shock to the drivetrain, and allows for smooth, gradual acceleration.
Torque Converter vs. Clutch: Which is Better?
While both torque converters and clutches serve the same purpose of transferring power from the engine to the wheels, torque converters are generally considered better for automatic transmissions, as they allow for smoother, more comfortable driving. Clutches, on the other hand, are better suited for manual transmissions, as they allow for more precise shifting.
How to Maintain Your Torque Converter
To keep your torque converter running smoothly, it’s important to maintain the right level and quality of transmission fluid. Regularly changing the transmission fluid and filter can help to prevent wear and tear on the torque converter, and improve overall transmission performance.

A continuously variable transmission is a superior automotive transmission that provides outstanding efficiency and smooth, powerful driving performance.
A continuously variable transmission is a transmission in which the ratio
of the rotational speeds of two shafts, as the input shaft and output
shaft of a vehicle or other machine, can be varied continuously within
a given range, providing an infinite number of possible ratios.
A continuously variable transmission need not be automatic,
nor include zero or reverse output. Such features may be adapted
to CVTs in certain specific applications.
Other mechanical transmissions only allow a few different discrete
gear ratios to be selected, but the continuously variable transmission
essentially has an infinite number of ratios available within a finite

engine, and the driven speed of the wheels to be selected within a
continuous range. This can provide better fuel economy than other
transmissions by enabling the engine to run at its most efficient
speeds within a narrow range.
