If you know anything about transmissions, you probably know that there are different types of transmission. You almost certainly will have heard about manual and automatic transmissions. You may not have heard of CVT transmissions, however. When buying or leasing a new or used vehicle, one of the things you should definitely consider is the transmission. But why type of transmission is better for you? Just what are the differences between a manual and automatic transmission? And what’s the deal with this mysterious third type of transmission?
The Manual Transmission
The transmission is the part of your vehicle that transfers the power generated by your engine to the axles, which turn the wheels, which makes your vehicle go. As you can see, it’s pretty important. But not all transmissions are the same. There are three basic types of transmission. The original type of transmission is the manual transmission.
The manual transmission, which is also known as a “standard transmission” or a “stick shift”, is a type of transmission that utilizes a driver-operated clutch to regulate torque transfer from the engine to the transmission. The clutch is typically engaged or disengaged by a foot pedal or hand lever. Because they are the simplest, mechanically speaking, of the three types of transmissions, they also often have the longest lives, because there is less to go wrong. They also often offer the best fuel economy and manual transmission vehicles are typically a bit cheaper. Some drivers even enjoy driving them more.
The Automatic Transmission
Manual transmissions are mechanically simpler, but they are more complex to use. Many drivers either don’t know how to drive a manual transmission or do not like the extra work involved. For such drivers, the best type of transmission is an automatic transmission. This type of transmission can automatically change gear ratios as the vehicle moves, meaning the driver does not have to shift gears manually.
Controlling a vehicle at low speeds is typically easier with an automatic transmission rather than a manual, because of a side effect of the clutchless fluid-coupling design called “creep” that causes the car to want to move while in a driving gear, even at idle. Fun fact: the automatic transmission was invented by Alfred Horner Munro of Regina, Saskatchewan, in 1921.
The CVT – Continuously Variable Transmission
The continuously variable transmission (CVT), also known as a shiftless transmission, is a variant of the automatic transmission that can change seamlessly through a continuous range of effective gear ratios as opposed to a fixed number of gear ratios. The CVT’s belt-driven design offers approximately 88% efficiency, which is lower than that of a manual transmission, but this can be offset by lower production cost and by enabling the engine to run at its most efficient speed for a range of output speeds.
