Buying a Hyundai Gearbox in South Africa
Hyundai is one of the makes where matching the right gearbox matters most, because the same nameplate can carry three completely different "automatics". A 1.6 T-GDI turbo car like the Kona or Tucson uses the D7UF1 7-speed dual-clutch (DCT); a newer naturally-aspirated petrol such as the i20 or Creta increasingly runs the Smartstream IVT, which is a CVT; and the everyday 2.0 petrol or 2.2 CRDi diesel uses a conventional torque-converter automatic (A6MF1, A6LF or the older 4-speed A4CF). They share no internals and won't interchange. The Creta is the trickiest of all — depending on engine it can be a manual, a 4-speed auto, an IVT or the DCT. If you're weighing up an engine at the same time, compare it against a used Hyundai engine so you can plan the whole job.
The DCT and the IVT drive most of the demand
The D7UF1 7-speed DCT is widely reported for shudder and limp-mode, with technical service bulletins and recall activity behind it — and the Smartstream IVT/CVT has drawn power-loss complaints (the subject of a US class-action). Both are exactly the boxes people come looking to replace. Clean open-market prices for the DCT and IVT are scarce in South Africa, so on those you should expect an indicative range and a quoted figure rather than a fixed shelf price. Always confirm whether the quote covers the control electronics or valve body, not just the casing.
When the gearbox isn't the real problem
DCT shudder, harsh shifts and limp-mode are often clutch-pack or control-unit faults rather than a dead gearbox, and IVT/CVT power loss can come down to the belt, pulleys or the control module. It's worth having the fault properly diagnosed before committing to a full box. If the car is older and you're weighing up the spend, it's also worth checking what it's worth for scrap first.
