In some of the latest cars out there, you can change gears by simply pressing a button, turning a knob or toggling a small joystick. Yet simultaneously, plenty of different vehicles still require motorists to use one foot for the clutch pedal and another for the gas, all while using one hand to control the gear-change lever through a definite design of positions. And many other current vehicles don’t possess any traditional gears at all within their transmissions.

But whether or not a vehicle includes a fancy automatic, an old-college manual or a modern-day continually variable transmitting (CVT), each unit must do the same work: help transmit the engine’s output to the traveling wheels. It’s a complex task that we’ll make an effort to make a little simpler today, starting with the fundamentals about why a transmission is needed to begin with.
Let’s actually begin with the normal internal combustion engine. As the fuel-air mix ignites in the cylinders, the pistons begin Variable Speed Drive Motor moving up and down, and that motion can be used 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 overall performance with the tires moving slower compared to the engine, while with an increased gear, optimum performance includes the wheels moving faster.
With a manual transmission, gear shifting is handled by the driver with a gear selector. A lot of today’s cars have got five or six forward gears, but you’ll discover older models with from three to six forwards gears offered.

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