Manual or automatic: which gearbox suits you?

Choosing between a manual and an automatic gearbox is partly habit and partly practical. Both can be a good choice, and both can be a bad buy if they have been neglected. This guide explains how they differ so you can decide with a clear head.

What the gearbox does

An engine works well only within a range of speeds, but the wheels must turn from standstill to motorway speed. The gearbox gives different ratios so the engine stays in a useful range. The question is who changes the ratios: you or the car.

Manual gearbox

You press the clutch pedal and move the gear lever yourself. It is mechanically simple and has been used for decades.

• Pros: usually cheaper to buy, simple to repair, and gives you direct control. Many drivers enjoy it.
• Cons: more effort in heavy traffic, stalling is possible, and hill starts take practice. The clutch wears, and a clutch driven roughly wears faster.

Automatic gearbox

The car changes gears for you. Several designs exist under the same word, which is why it pays to find out which one a car has.

• Torque converter automatic: the classic type. Smooth, and generally robust when maintained.
• Dual-clutch: two clutches pre-select gears for fast, efficient shifts. It can feel less smooth at crawling speeds and can be costly to repair if neglected.
• Continuously variable (CVT): no fixed gears, just a smooth range of ratios. Comfortable, but the sound can feel unusual, and the type needs careful maintenance.
• Automated manual: a manual gearbox with a computer working the clutch. It is often cheaper, but the shifts can feel jerky.

Electric cars usually have a single fixed gear, so there is nothing to shift. See EV basics for buyers.

Which is easier to live with?

In stop-and-go traffic an automatic is much more relaxing. On open roads, either works well. If you drive mainly in a city, or have a physical reason to prefer fewer controls, an automatic is a strong choice. If you like control, drive on varied roads or want the lowest purchase price, a manual may suit you better. If you have only ever driven one type, plan some practice time before the other.

Running costs

Years ago automatics used clearly more fuel; today the difference is small and sometimes reverses, because a good automatic can shift more efficiently than an average driver. Purchase price can still be higher for an automatic, and repairs on complex units can cost more. Gearbox oil changes matter on many automatics, even where the maker once called the oil "lifetime". Use the cost of ownership tool to see how the totals compare for your own case.

Checking a used manual

• Test the clutch: the pedal should feel even, and the car should pull away smoothly without slipping or shuddering.
• Shift through all gears, including reverse. Crunching, popping out of gear or a notchy lever are warnings.
• Listen for whining or humming that changes with speed.
• Watch for oil leaks around the gearbox.

Checking a used automatic

• Start the car cold and move the selector through every position. Engagement should be quick and smooth, without a bang.
• During the test drive feel for hesitation, flaring revs between gears or harsh shifts. See the test drive checklist.
• Ask for the service history and whether the gearbox oil has ever been changed.
• Warning lights relating to the gearbox should never be present; see dashboard warning lights.

Resale

Buyer preference differs between places and car types. In some markets automatics sell faster, in others manuals are the default. Think about how easy your choice will be to resell, though your own comfort matters more for a car you keep for years.

Driving tips for each type

In a manual, avoid resting your foot on the clutch pedal and do not hold the car on a hill with the clutch; use the handbrake. In an automatic, come to a complete stop before changing between drive and reverse, and use park with the handbrake when you leave the car. Both habits reduce wear and are cheap to learn. If the manual gives a different instruction for your gearbox, follow the manual.

What to remember

• Manual: simple and usually cheaper, but more effort in traffic.
• Automatic: comfortable, with different designs that behave and age differently.
• Find out which automatic type a car has before buying.
• Service history matters most on gearboxes, particularly automatics.
• Try both on a test drive if you are unsure.
