my Mazda CX-5 gearbox began jerking when car is cold so I asked around and found this shop. They performed a full overhaul on the transmission. The SUV now changes gears smoothly during normal driving. Service was completed on time and the final bill matched the initial quote.

A complex job on my Porsche Cayenne Hybrid gearbox, but they nailed it. The system is now seamless, and the 2-year warranty gives real peace of mind.

Highly recommend for you to look for gearbox king for any type of gearbox repair or overhaul! Staff are friendly and knowledgeable to explain to me the process, the cost and how long it will take. Transparent pricing and repair was smoothly done. I managed to collect the next day with no reoccurring issue after 1 week since collection

Took my Mercedes C-Class in because the transmission was jerking hard between gears. The guys sorted out the mechatronic unit and did a thorough service. Driving feels smooth and responsive again. Quick work, clear updates, and no hidden charges.

Just had the gearbox oil changed on my Mazda 3. The difference is noticeable straight away. Gears engage cleaner and the whole drivetrain feels quieter and more willing. They used proper specification fluid, showed me the old dirty stuff, and wrapped it up fast. Honest pricing with no upsells

We only do gearboxes

Drive down to Sin Ming AutoCity and we'll take a look. No hard sell.

We diagnose first, then quote

Limp mode and a warning light could be a worn clutch pack. It could also be a sensor or a solenoid that costs a fraction to put right. The two are worlds apart on the bill.

That is why we diagnose before we quote. We confirm the exact fault with dealer-level tools, explain it in plain English, and give you a price before any spanner comes out. You decide with the full picture in front of you.

The warranty, in plain terms

Every gearbox overhaul is covered for two years or 40,000km, whichever comes first. That is the rebuild, in writing.

Servicing and oil changes are maintenance, not a rebuild, so they do not carry a workmanship warranty. We'll tell you straight which one your car needs.

From PDK to CVT, we know the box

Singapore's stop-start traffic and heat are hard on a transmission. Each type fails in its own way.

Automatic (AT). Fluid breaks down in the heat, clutches and solenoids wear, and shifts turn rough.

CVT. Belts and pulleys slip under load. Fluid condition matters more than most owners think.

Dual-clutch (DCT/DSG). The clutch packs, the valve body and the mechatronic unit are the usual suspects, often with erratic shifts and dash errors.

Porsche PDK. A sophisticated box that takes hard, high-speed shifting to heart. We treat it accordingly.

Whatever you drive, we know how the box behaves and how to put it right.

Can't drive it in? We'll fetch it

A gearbox that has given up does not care where you are. Stuck on the expressway or sat in the carpark, the car is going nowhere.

So we come to you. Free towing for gearbox repairs, anywhere in Singapore. Send us your location on WhatsApp and we'll arrange collection.
