What are the Four Main Types of Transmissions?
Shopping for a new car can be so much fun! There might be some terminology being used, though, that has you wondering what type of transmission you’re getting with your purchase. Here’s a quick rundown of the four most common types of transmissions so that you can make an informed decision when making your next vehicle purchase.
Four Main Types of Transmissions
Automatic transmission
This is a common term with which you might already be familiar. An automatic transmission allows drivers to operate their vehicles without having to manually shift or use a clutch. The vehicle itself will switch gears for you, most often through six different speeds. It most likely uses a hydraulic system to switch gears which depends on pressurized fluid, pumps and a converter to guide the vehicle through different gears depending on the power being asked of the engine.
Manual transmission
Another common transmission, manual transmissions, are often used by drivers that want more control over their vehicle’s performance. A manual transmission allows drivers to use a clutch and gear shift to indicate when they want their vehicle to switch gears. Older vehicles typically had four speeds, but most of today’s trucks and sports cars offer five or six speeds.
Automated manual transmission (AMT)
This offers the benefits of both an automatic and manual transmission. Essentially, having an automated manual transmission means that the vehicle has a manual transmission, but that the car itself (through the computer) can shift for you. Autotrader notes that some of the perks of having an AMT are that you get to drive like an automatic without having to pay attention to RPMs or shifting, but you get the fuel economy and acceleration performance of a manual transmission. Some drawbacks include that the shifting can feel jerky/abrupt at low speeds just like in a regular manual. It depends a bit on make and model, so a test drive here will be very important in getting a feel for a vehicle with AMT.
Continuously variable transmission (CVT)
The newest transmission on our list, a continuously variable transmission, is also a form of automatic transmission, where the driver does not have to shift manually. The CTV has an unlimited number of gears due to its layout, where cone-shaped pulleys are moved with a chain or belt. This provides a smoother, more even shift, and allows the car to be more responsive to each individual’s driving style. J.D. Power shares that pros of the CTV are better fuel economy, responsive acceleration and smooth transitions, while cons can include some additional noise and higher repair costs.
What’s the right transmission for you?
All of these transmissions offer benefits and drawbacks, so it really boils down to your driving wants and driving style. For those that want a hands-on experience, the manual transmission could be the right fit. For shoppers looking for a more automated experience, an automatic, AMT or CTV would be best.
