In some of the most recent cars out there, you can shift gears by simply pressing a button, turning a knob or toggling a little joystick. Yet at the same time, plenty of Variable Speed Transmission different vehicles still require motorists to make use of one foot for the clutch pedal and another for the gas, all while using one hand to manipulate the gear-shift lever through a definite pattern of positions. And several other current vehicles don’t have any traditional gears at all in their transmissions.

But whether or not a vehicle includes a fancy automatic, an old-college manual or a modern-day continuously variable transmission (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 bit simpler today, you start with the fundamentals about why a tranny 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 begin moving up 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 faster 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 lower gear means optimum functionality 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 discover older models with from three to six ahead gears offered.

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