Which automatic to buy in India: AMT, CVT, DCT or torque converter

The short answer

If your driving is mostly city stop-go and the budget is tight, an AMT is the one to buy. Maruti sells it as AGS, and on its own website the Swift's petrol AMT is rated at 25.75 km/l against 24.8 km/l for the petrol manual, so you are not paying for convenience with fuel.

If you want smoothness above all, pick a torque converter automatic or a CVT. If you want quick shifts behind a turbo-petrol engine, pick a DCT, but read the heat warning below first.

What each gearbox actually is

An AMT is a manual gearbox with robots doing the clutch and shift work. There is one clutch, few extra parts and no new fluid circuit, which is why it is the cheapest automatic on sale. The trade-off is the pause and head nod between shifts, which you feel most on an uphill crawl.

A torque converter AT uses fluid to pass drive from engine to gearbox, which is why it creeps forward smoothly and never jerks. Maruti's technology page lists a 4-speed AT on the Ciaz and Jimny, and a 6-speed AT on the Ertiga, Brezza, XL6, Grand Vitara Smart Hybrid and the 1.0 Boosterjet Fronx.

A CVT has no fixed gears. Maruti describes it as two belt-driven pulleys worked by a transmission control unit to reach the ratio it wants, and lists it on the Grand Vitara Intelligent Electric Hybrid. Revs rise and hold, which some buyers read as a slipping gearbox when it is simply how the hardware works. The same page lists the e Vitara's single-speed electric drive as an e-CVT.

A DCT has two clutches. Hyundai's own explainer says one handles the odd gears, the other the even gears and reverse, and the next gear is pre-selected so a shift takes under one second with no break in drive. Hyundai India offers its 7-speed DCT on the i20 N Line, Venue and Venue N Line, Verna 1.5 Turbo GDi, Creta and Creta N Line and the Alcazar. Tata offers a 7-speed wet clutch DCA on the Nexon alongside a 6-speed manual and AMT.

The trade-off nobody mentions at delivery

Dry clutch DCTs are light and efficient on small engines. Wet clutch versions sit the plates in oil, which cools them and lets them take more torque and harder use. That matters in Bengaluru or Mumbai traffic, where a dual clutch spends its life slipping at crawl speed.

Read Hyundai's own guidance on this. It asks DCT owners to avoid prolonged creeping in traffic, to brake firmly at stops rather than inching along, and to shift to neutral during a long standstill so heat does not build up. No manufacturer says that about a torque converter. If your commute is 10 km of bumper-to-bumper, a torque converter AT or a CVT asks less of you and of the hardware.

Why automatic prices should ease by 2029

Aisin, the Toyota group supplier that builds much of the world's automatic hardware, said in February 2026 that it will invest about 32 billion yen in India. About 16 billion yen expands its Rohtak plant in Haryana by roughly 24,000 sq m to build CVTs, and about 16 billion yen builds a new plant at Sambhajinagar in Maharashtra, about 86,000 sq m, for automatic transmissions and body parts. Both are planned to start in 2029. Aisin's reason is plain in the release: demand is shifting from manual to automatic, so there is greater need to make automatics locally.

Localised ATs and CVTs mean less imported content in the gearbox, which is the single biggest reason an automatic variant still costs more than the manual. Until then, the honest buying rule stands. Heavy city use favours AMT or torque converter. Highway and spirited driving favour DCT. A strong hybrid takes the choice away from you, since the ratio is managed by the hybrid unit itself.
