The transmission turns the engine's power into the right speed for the wheels. Here's what each kind is, what a CVT really is, and how each one feels to drive.
The short version: automatics and CVTs both shift for you. A CVT has no fixed gears, so it feels smoother and usually saves gas. A manual has a clutch pedal and a stick, and it's getting rare.
The three you'll see most
Automatic
A set of fixed gears, usually 4 to 10, that the car shifts through for you. How it feels: small steps as it shifts. Good to know: common on trucks, SUVs and anything built to tow; check the car's records for fluid service.
CVTContinuously variable
No fixed gears at all: two pulleys and a belt change the ratio smoothly. How it feels: very smooth, with a steady hum under hard acceleration. Good to know: usually the best gas mileage of the three.
ManualStick shift
You press a clutch pedal and move the shifter yourself. How it feels: the most connected to the car, and takes practice. Good to know: the clutch wears with use and is eventually replaced.
So what is a CVT?
CVT stands for continuously variable transmission. Instead of a set of gears, it has two cone-shaped pulleys joined by a steel belt or chain. As the pulleys squeeze together or spread apart, the belt rides higher or lower on each one, so the ratio changes smoothly with no steps.

Because it can pick any ratio in between, a CVT keeps the engine at its most efficient speed, which is why it usually saves gas. Press the pedal hard and the engine may hold a high, steady hum while the car catches up. Many newer CVTs fake a few "shifts" so they feel more familiar.
Service records matter. A CVT likes its fluid changed on schedule, and some makers extended CVT coverage on certain years. Each model guide says if one applies, and we'll show you the car's records.
Less common types
Hybrid eCVTPrius, RAV4 Hybrid, Subaru hybrids
Not a belt-and-pulley CVT: planetary gears and electric motors blend gas and electric power. It feels like a smooth CVT.
Dual-clutch (DCT)Some VW, Audi, Ford, Hyundai
Two computer-run gearboxes, one for odd gears and one for even. Very quick shifts, and can feel jerky at parking-lot speeds.
Automated manualRare
A regular manual where a computer works the clutch and shifts. Shifts can feel slow, with a pause between gears.
Single-speedElectric cars
Electric motors work across a huge speed range, so most EVs have just one gear.
Which one fits how you drive?
Commuting, errands, best gas mileage
CVT, or a hybrid's eCVT
Towing a trailer or hauling heavy loads
A regular automatic, and check the towing rating
You like to shift, or want the simplest setup
Manual
Every listing's details say Automatic, CVT or Manual, and each model guide's "Engines and transmissions" table shows which ones that generation came with.
