Responsible for transferring power from the engine to its wheels, a car’s transmission is integral to how it operates and handles. Three types of transmission gearboxes, each with unique qualities, power today’s automobiles: automatic, manual, and continuously variable transmissions (CVTs). Here’s a guide to the main differences between them.

An Introduction to Automotive Transmission Types

Automatic

In the past, an automatic transmission was available only on luxury vehicles, but this is no longer the case. As the name suggests, if you have an automatic transmission, gears shift automatically as your speed and road conditions change. Thanks to a torque converter, an automatic gearbox detects when you’re accelerating, going uphill, or heading downhill and shifts gears accordingly. Automatic transmissions suit drivers who are just learning to drive as well as those who appreciate convenience. 

Manual

Outside the United States, the cars in most countries have manual gearboxes, commonly referred to as stick shifts. Instead of letting a torque converter decide when it’s time to change gears, it’s up to the driver. Most manual transmissions have five or six gears. To switch gears, the driver engages a clutch, usually a pedal on the floor, to temporarily disconnect the engine from the wheels. Once they’ve shifted again into gear, they can continue driving. Failing to engage the clutch when shifting damages the transmission. A manual transmission is recommended for anyone who wants more control over the handling of their car. 

Continuously Variable Transmission (CVT)

Instead of traditional gears, a CVT relies on a system of pulleys and belts. This system allows for smooth transitions and a greater variety of gear options. Some drivers may feel that CVTs operate a bit more slowly than either an automatic or manual gearbox. Like an automatic transmission, a CVT is recommended for drivers who like simplicity
