Hyundai cars use its own developed classic automatic transmissions (AT), CVT and dual-clutch DCT transmissions, depending on the model and engine.
What gearboxes are used in Hyundai cars?
- 6-speed and 8-speed AT – i30, Tucson, Santa Fe, Sonata.
- IVT (CVT) – i20, i30, Kona, Venue.
- 7DCT / 8DCT (dual clutch) – i30 N, Tucson, Santa Fe (more powerful engines).
How is the repair going?
- Diagnostics – checking electronics, pressure, clutches (DCT) or pulleys (CVT).
- Disassembly and troubleshooting – analysis of friction, solenoids, clutches, valve blocks.
- CVT repair (IVT) – pulley, chain or belt replacement.
- DCT clutch and mechatronics repair – necessary for sporty driving.
- AT hydraulic unit repair – frequent due to overheating or impacts.
- Oil change – important for all gearboxes, using the correct specification.
The most common problems:
- CVT (IVT): noise, slipping, overheating.
- DCT: jerking, lag, clutch wear.
- AT: shocks, loss of pressure, solenoid damage.
Technical disadvantages:
- CVT: oil and temperature sensitivity.
- DCT: expensive repair in case of mechatronics failure.
- AT: Requires regular maintenance in severe conditions.
Approximate Hyundai gearbox repair costs:
- CVT repair (IVT): €1000–2200
- DCT clutch/mechatronics repair: €1200–2500
- AT hydraulic unit repair: €900–1500
- Oil change (all types): €250–400
- Full AT repair: €1500–2800
