Automatic Transmissions

audi-1193214_1920Manual transmissions, in which a driver-operated clutch is utilized to change gears, have been becoming increasingly less popular in recent years. There are a lot benefits to using a manual transmission, or a “stick shift,” but many people are opting for automatic transmissions now. This is typically because even though automatics require a little more maintenance than manuals, they are simpler to use and have less of a learning curve. So, if a manual changes gears manually, the automatic must change automatically, right? That is the basic idea behind it, however there is more than just one kind of automatic transmission. Automatic transmissions can be separated into three different types: fully automatic, semi-automatic, and continuously variable transmissions. We’ve outlined some of the basics of each below.

Fully Automatic Transmissions
These are the most common kind of transmission installed in cars today. In fact fully automatic transmissions consist of more than 90% of new cars sales in America. This has to do with the fact that it is completely capable of shifting gear ratios automatically, making it very user-friendly and easy for people to learn how to use. This does, however, come with a price. They these tend to be more expensive than manuals and are more costly to repair usually.
Semi-Automatic Transmissions
Semi-automatics, as the name suggests, are a mix between manuals and automatics. The most common use for these is in high end sports cars like Ferraris and Porsches. The manual part of this type of transmission is that you still need to manually switch gears, the transmission will not do it automatically. However, it differs from a manual transmission because it is not necessary to engage and disengage the clutch and instead uses electronic sensors, processors, actuators, and pneumatics to shift gears when the driver intends to.
Continuously Variable Transmissions
Continuously variable transmissions, often referred to as CVTs, uses a different system to change gears, instead of toothed gears like a fully automatic system, CVTs utilize a pulley system. This makes shifts much smoother and free of hesitations and allows the engine to run at the optimal revolutions per minute. This transmission is best for fuel efficiency.
