What is a transmission? 

Transmission History? Transmission repair is something, like a car, owner we all dread. When the time comes, it’s a good idea to understand how they work and why break down. 

Alfred Horner Munro is the inventor of the transmission. He invented it in 1991. Howard Frederick Hobbs invented the first car transmission. He did accomplish this in 1932. 

The different kinds of transmissions are manual, automatic, and CVT transmissions. A manual transmission shifts gears by you pushing the clutch and using the stick lever. An automatic transmission shift gears automatically while you driving! A CVT transmission can shift gears during high speeds of rough driving.

Transmission history

Transmission history over the years has evolved a long way from where they are today. In the beginning, there were only manual transmissions. Back when all the cars were manual, there were no other options. They were simple cut meshing gears inside a case with some gear oil. 

The second transmission that was built for cars was the synchromesh transmission in 1919. It was invented by Earl A Thompson. This transmission was still a manual transmission but, it was a little different.

 Then came the automatic transmission. The first person to invent an automatic transmission was Alfred Horner Munro. He invented the automatic transmission in 1921. Of course, our automotive transmission has evolved from what Alfred left it. Other car companies have made their transmissions for their cars but Alfred Munro made his for General Motors or GM as we might know them. 

After that, was the manumatic transmission in the 1950s. Then, the sequential manual gearbox transmission. Which was invented in 1996.  And to top it, the dual-clutch transmission 1939 was invented by  Adolphe Kégresse.

Your car’s transmission is one of the most important machines in your car. It converts the power from the engine to the wheels. There are many different kinds of car transmissions. Some are automatic transmissions, some are manual transmissions. The transmission, uses the pressure plate, clutch, and flywheel, to take the torque from your engine, and move it to your clutch, the gearbox, then the wheels! 

Manuals are slowly being faded out. Nowadays, very few cars come in true stick shift transmission. Most manuals are now in a form of a paddle shifter or dual-clutch transmission. Have you ever wondered how the transmission works? The process is different depending on whether or not you have an automatic transmission or and manual transmission.

Manual transmissions have a clutch pedal and a shifter. This allows the driver to manually change gears instead of the car doing it for you. Manual transmissions have gears that consist of a set of gears along with two shafts, and input and output shafts. The driver has to select the proper gear for that clutch. The clutch is sandwiched in-between the flywheel and the pressure plate.

What Does Transmission Fluid Do?

What does transmission fluid do for a car? Well, transmission fluid is very important. It lubricates the mechanical parts, helps maintain fluid pressure in your vehicle, cools your transmission so that it doesn’t get too hot, helps prevent oxidation, conditions your gaskets, and prevents rust from forming on your car.  


The first transmission fluid was a special lubricant GM. It was used in a 1940 Hydra-Matic 4-speed transmission. “This transmission fluid was only available at Oldsmobile, Pontiac, and Cadillac dealerships.” 

9 years later GM makes another type of transmission fluid. The type A transmission fluid. Ten years later, in 1959, Ford makes their own transmission fluid. 

DEX fluid

DEX transmission fluid is another kind of transmission fluid! DEX transmission fluid is found in cars that have automatic transmissions. DEX transmissions and DEX transmission fluid were invented in 1967.

As you can tell, transmission fluid does a lot. But, did you know that there are multiple kinds of transmission fluid? Well, there is! One kind of transmission fluid is the type F fluid. Type F fluid was commonly used in the ’70s. This kind of transmission fluid didn’t have friction modifiers. (Friction modifiers help to reduce friction on lubricated parts. 

CVT stands for continuously variable transmission. One type of transmission fluid is CVT. The CVT transmission is the most common transmission being produced today. In 1879, the first CVT transmission was invented.

CVT transmission was designed by Milton Reeves. Milton had over 100 patents for all of his inventions. Reeves built the muffler, the transmission, busses, and more! Milton died in 1925. Unfortunately, he only lived for 60 years!  

It was produced under Subaru. The first car to have a CVT transmission was the 1958 DAF 600. Although they’d been around for a very long time, CVT transmission started becoming more and more popular in the later 1980s.
