A transmission is a gear box attached to a vehicle’s engine; the transmission gives vehicles different speeds.
By engaging the clutch, you can change gears on a shifter, or if your vehicle has an automatic transmission, they change gears on their own.

Some tractors need a lot of torque to pull plows, but they need to go fast on dirt roads to get from field to field. So often ¾ of the gears are for the field and the others for the path. As for example for our Kubota M110X, the first 12 gears are for the field but the last 4 are for the path. But not all tractors have the same transmission; tractors that have less horsepower have a smaller transmission. For example, our smallest tractor is a Kubota M6800 with 70 hp, and our largest tractor is the Kubota M110X which has 110 hp. The M6800 has an 8-speed drivetrain, and the M110X has a 16-speed drivetrain. Why? Because the bigger the transmission is, the more power is required.
Basically it has different transmissions for different jobs; for example, a trailer truck, or a tractor needs a lot of gears, so you can pull big loads, but you can still go fast on the way. But a car has a small 4-gear automatic transmission to carry the world. But you can have different transmission options in the same vehicles. Like for example if you want a truck that hauls light loads it has a 6 gear transmission, but if you want your truck to pull heavy loads it can have a 10 gear transmission.
Many trailer trucks have what is called a “Jake Brake” which assists the truck in downshifting to stop them. The transports have probably the coolest transmissions!
Emile Levassor and Louis-René Panhard are credited with developing the first manual transmission in 1894. Levassor and Panhard used a chain drive on their original transmission. Their invention is still the fundamental starting point of contemporary manual transmissions. Not too long after that Alfred Horner Munro, a Canadian steam engineer, designed the first automatic transmission in 1921 and patented the transmission in 1923. He created the automatic transmission with four forward gears and no reverse or park gear, and it used air pressure instead of hydraulic fluid. Over the years the transmissions have evolved to be bigger, faster, more gears, and more torque!
And that’s all! Thanks for reading!
