In a few of the most recent cars on the market, you can change gears simply by pressing a button, turning a knob or toggling a little 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 when using one hand to manipulate the gear-change lever through a definite pattern of positions. And several other current vehicles don’t possess any traditional gears at all within their transmissions.

But regardless of whether a vehicle has a fancy automatic, an old-college manual or a modern-day continually variable tranny (CVT), each unit has to do the same job: help transmit the engine’s output to the driving wheels. It’s a complex task that we’ll make an effort to make a little simpler today, you start with the basics about why a transmitting is needed to begin with.
Let’s actually start with the typical internal combustion engine. As the fuel-air mixture ignites in the cylinders, the pistons start moving up and down, and that Variable Speed Transmission movement is utilized to spin the car’s crankshaft. When the driver presses on the gas pedal, there’s more fuel to burn in the cylinders and the whole 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 efficiency with the wheels moving slower than the engine, while with a higher gear, optimum performance includes 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 possess five or six forwards gears, but you’ll discover older models with from three to six forwards gears offered.

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