In a few of the most recent cars available, you can shift gears simply by pressing a button, turning a knob or toggling a small joystick. Yet simultaneously, plenty of different vehicles still require drivers to make use of one foot for the clutch pedal and another for the gas, all while using one hand to control the gear-shift lever through a distinct design of positions. And several other current cars don’t possess any traditional gears at all in their Variable Speed Drive Motor transmissions.

But regardless of whether a vehicle has a fancy automatic, an old-school manual or a modern-day continuously variable transmitting (CVT), each unit must do the same job: help transmit the engine’s result to the generating wheels. It’s a complex task that we’ll make an effort to make a bit simpler today, you start with the fundamentals about why a tranny is needed in the first place.
Let’s actually begin with the normal internal combustion engine. As the fuel-air combination ignites in the cylinders, the pistons begin upgrading and down, and that motion is utilized to spin the car’s crankshaft. When the driver presses on the gas pedal, there’s more fuel to burn off in the cylinders and the complete process moves quicker and faster.

What the transmission does is change the ratio between how fast the engine is spinning and how fast the driving wheels are moving. A lesser gear means optimum performance with the tires moving slower compared to the engine, while with an increased gear, optimum performance comes with the wheels moving quicker.
With a manual transmission, gear shifting is handled by the driver with a gear selector. A lot of today’s vehicles have five or six forward gears, but you’ll find older models with anywhere from three to six ahead gears offered.

A clutch is used to transmit torque from a car’s engine to its manual transmission. The various gears in a manual transmission allow the car to travel at different speeds. Larger gears offer plenty of torque but lower speeds, while smaller sized gears deliver much less torque and invite the car travel more quickly.
