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.

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
range, so it enables the relationship between the speed of a vehicle,
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.
