Perodua.
Perodua runs Malaysia's roads — and its gearboxes are correspondingly the most common units in any workshop. The older 4-speed automatics in the Myvi and Axia are simple, tough and cheap to fix. The newer D-CVT in the Ativa, Alza and facelifted Myvi range brings Daihatsu's split-gear design, which reduces belt load but demands the right fluid.

What's fitted
| Unit | Type | Found in | Specialist note |
|---|---|---|---|
| 4AT (Daihatsu/Aisin) | Conventional automatic | Myvi (pre-2022), Axia, Bezza, Alza (old) | Simple, proven, inexpensive to overhaul — the workhorse of Malaysian motoring. |
| D-CVT | CVT with split gears | Ativa, Alza (new), Myvi facelift, Axia (new) | Gear drive at low speed, belt drive at cruise — clever design that cuts belt wear significantly. |
Known failure modes
Fault 01
Delayed engagement / flare between gears (4AT)
Usually degraded fluid or worn solenoids first, clutch packs second. Caught early it's a service; late, it's an overhaul — still one of the cheapest overhauls in the market.
Fault 02
Shudder on take-off (D-CVT)
Early D-CVTs are sensitive to fluid condition and software calibration. The correct Daihatsu-spec fluid matters — generic CVT oil causes exactly this complaint.
Fault 03
Whine at constant speed
On high-mileage 4ATs, differential and bearing wear inside the transaxle. Worth quoting alongside any overhaul.
Cost band · Malaysia
RM 150 (diagnosis) to RM 3,500 (4AT overhaul); D-CVT work RM 2,500–5,000

Perodua owners ask
- 01How much to repair a Myvi automatic gearbox?
- For the 4AT: a fluid and solenoid service runs a few hundred ringgit; a full overhaul typically RM 2,500–3,500 including parts. It's among the most economical gearboxes in Malaysia to put right.
