Singapore’s Top Rated Gearbox Rebuild Specialist with 2-Year Warranty
Thousands of automatic gearboxes rebuilt perfectly
A Gearbox Rebuild Is Not a Repair. It Is a Reinstatement.
There is a meaningful difference between a gearbox patch up and gearbox rebuild. A repair addresses what is visibly broken. A gearbox rebuild addresses everything that has worn, degraded, or is about to fail, puts it back together with precision, and gives you a transmission that performs the way it did when the car was new.
Most car owners in Singapore hear “gearbox rebuild” and assume the worst. Weeks of downtime. A bill that makes their eyes water. A process so complex that only a dealer can handle it.
None of that is accurate when the job is done by people who do this every day.
We have completed over 2,000 gearbox rebuilds across every major car brand on Singapore roads. European, Japanese, Korean. Automatic, CVT, dual clutch, PDK. We rebuild gearboxes the right way, with the right parts, backed by Singapore’s longest warranty: 2 years or 40,000km.
Free diagnosis before anything else. Transparent pricing before we start. No surprises when you collect.
What Customers Say About Us
Why "Gearbox Rebuild" Is the Word That Matters
When a gearbox is sent to a specialist for a rebuild, the process is fundamentally different from what happens when a general workshop swaps in a used unit or does a flush and hope.
Here is what a proper gearbox rebuild actually means.
The entire transmission unit is removed from the vehicle and completely disassembled. Not partially stripped. Fully taken apart so that every internal component is physically accessible and can be individually inspected.
Once the gearbox is open, every consumable component is replaced as standard. This includes the clutch packs, all internal seals, all gaskets, the transmission filter, and the correct manufacturer-specification transmission fluid for your exact model. These are the components that wear out over time and that determine how the gearbox performs. Replacing them completely is what turns a tired transmission back into one that feels new.
Components outside the gearbox casing, such as the engine, flywheel, control modules, torque converter, valve body, oil pan, and autocooler, are not replaced as part of a standard rebuild unless inspection during the diagnosis reveals they are faulty. You pay to fix what is worn. Not a blanket parts list that includes items your car does not need.
After the rebuild, the gearbox is reassembled with precision, refitted to the vehicle, and the car is road-tested and scanned before it is returned to you. If there is anything not right, it stays in the workshop until it is.
That is a gearbox rebuild. That is what we do.
⚠️ A gearbox rebuild done at the right time, when symptoms first appear, costs a fraction of what a full replacement unit costs. The longer a known gearbox fault is driven on, the more internal components sustain secondary damage and the larger the eventual job. Do not wait.

What Makes a Gearbox Rebuild Different From Other Options
Most car owners are presented with a limited set of options when a gearbox develops a fault. The dealer recommends a replacement unit. The cheaper workshop suggests a flush. A third party offers a reconditioned unit from a scrapyard.
A rebuild is the option that none of them typically lead with, despite it usually being the most sensible one.
Versus a full replacement unit from the dealer Dealer replacement units are new or factory-remanufactured. The cost reflects that. For most cars on Singapore roads, a dealer gearbox replacement runs from S$8,000 to well over S$20,000 depending on the model. A rebuild of your existing unit achieves the same outcome at a fraction of that cost, and your gearbox number stays unchanged which means no LTA complications.
Versus a reconditioned unit from a scrapyard Reconditioned units carry unknown history. They were removed from another car, of unknown mileage, with unknown maintenance history, and unknown prior damage. They typically come with 1 month warranty. If they fail, you are back to square one. A rebuild of your own unit means you know exactly what went into it, and it comes with our 2-year / 40,000km warranty.
Versus a fluid flush A transmission fluid flush changes the fluid. It does not address worn clutch packs, degraded seals, failing solenoids, or any of the mechanical components that cause gearbox faults. For certain mild, early-stage issues a fluid service is appropriate. As a response to a gearbox that is slipping, shuddering, or showing fault codes, it is not a fix. It is a delay.
A rebuild fixes the actual problem. That is the difference.
Singapore’s Longest Gearbox Rebuild Warranty
2 Years / 40,000km. Whichever comes first.
This is the longest gearbox rebuild warranty available in Singapore. Most workshops offer 1 to 6 months on gearbox work. Scrapyard reconditioned units come with 1 month. We give you 2 years or 40,000km because every gearbox we rebuild leaves our workshop built to last 100,000km or more under normal driving conditions.
The warranty is not a marketing line. It is a reflection of how we rebuild. The parts we use, the standard we rebuild to, and the testing we carry out before the car leaves. If we were not confident in the outcome, we would not offer it.
Rebuilt to last 100,000km or more

Gearbox Rebuild Warning Signs: When Your Car Is Telling You Something
Gearboxes rarely fail without warning. The warning signs are often present weeks or months before a fault becomes critical. Knowing what to look for is what separates a S$2,500 rebuild from a S$12,000 replacement.
Slipping or Flaring The engine revs climb but forward motion does not match. The gearbox is not maintaining positive drive through gear changes or across a CVT ratio band. Internal clutch pack or belt wear is usually the cause.
Shuddering or Juddering A vibration through the car under light acceleration, at a specific speed, or when pulling away from a standstill. Can be torque converter related, clutch pack wear, or in CVT-equipped cars, pulley or belt deterioration.
Delayed or Rough Gear Changes Shifts that feel late, heavy, or noticeably different from how they used to feel. The gearbox is losing the hydraulic precision that makes gear changes smooth. Solenoid wear or clutch pack degradation are common causes.
Warning Lights on the Dashboard Any transmission-related warning light needs a proper diagnostic scan with brand-specific equipment. Not a generic reader. Not a code clear. An actual diagnostic scan that tells you what fault has been logged and why.
Limp Mode The transmission control module has restricted the gearbox to protect it from further damage. This is not a fault to drive through. Stop driving and arrange a diagnostic check. The limp mode is the car protecting itself. Overriding it causes the damage the system is trying to prevent.
Noise in a Specific Gear or Speed Range Whining, grinding, or clunking that appears consistently at a specific speed or during a specific gear. Internal wear is progressing in a specific part of the gearbox.
Fluid Leak Reddish or brown fluid under the car after parking. Seal degradation. Low fluid levels accelerate internal wear and can turn a rebuild into a replacement if left unaddressed.
💡 The most expensive gearbox rebuild is the one you delay. Every kilometre driven on a symptomatic gearbox adds wear to components that were not originally part of the problem. Come in for a free diagnostic check the moment something feels different.
Gearbox Rebuild Process: What Happens When You Bring Your Car In
Step 1: Free Diagnostic Scan and Physical Assessment Brand-specific diagnostic equipment for every make. We read the full fault memory, not just the codes that show on a generic scanner. We also physically assess the gearbox externally before opening anything. No charge. No obligation. You get the honest picture first.
Step 2: Transparent, Itemised Quote We tell you exactly what the rebuild involves, which components are being replaced, and what it costs. You see the full breakdown before we start. No additions at collection time. What we quote is what you pay.
Step 3: Full Gearbox Rebuild The gearbox is removed, completely disassembled, and every consumable internal component is replaced. Clutch packs, seals, gaskets, filter, correct-specification fluid. Rebuilt with original manufacturer parts or OEM-grade equivalents. 3 to 5 working days for most makes and models.
Step 4: Road Test and Post-Rebuild Verification Every rebuilt gearbox is road-tested across a range of operating conditions before the car is returned. We also carry out a final diagnostic scan to confirm no fault codes remain. The car does not leave until it is right.
Step 5: Collect with Singapore’s Longest Warranty 2-year / 40,000km warranty issued at collection. Longest available in Singapore for gearbox rebuild work. Drive away with confidence.
Volkswagen Gearbox Issue
If you are driving a Volkswagen or Audi with a dual-clutch gearbox (DSG), you typically do not need a full gearbox overhaul when issues arise. The most common problems are usually related to either the clutch or the mechatronic unit. Since the clutch is a mechanical component, the symptoms are usually more consistent, such as a noticeable loss of power or the inability to engage either the odd or even-numbered gears, which is a characteristic of dual-clutch systems. On the other hand, if the mechatronic unit is faulty, the gear shifts tend to be erratic, and you may notice error messages on the dashboard. In some cases, the issue may temporarily resolve after restarting the engine. At 1 Car Service Workshop, we are experienced in diagnosing and repairing these common DSG gearbox issues, ensuring your Volkswagen or Audi operates smoothly and reliably.
Gearbox Rebuild Across All Makes and Models
We carry out gearbox rebuilds across the full spectrum of cars on Singapore roads. This covers all automatic gearbox types including conventional torque converter automatics, continuously variable transmissions, dual clutch transmissions, and the specialist gearbox systems found in performance and luxury European cars.
European Makes Mercedes-Benz, BMW, Audi, Volkswagen, Porsche, Volvo, MINI, Peugeot, Renault, Citroen, Jaguar, Land Rover, SEAT, Skoda, Opel, Maserati, Bentley, Ferrari, Rolls-Royce, Lamborghini.
The ZF 6HP and 8HP automatic units common across BMW, Audi, Jaguar, Land Rover, Volvo, Maserati, Bentley and Rolls-Royce are among the most frequently rebuilt gearboxes we handle. Mercedes 7G-Tronic and 9G-Tronic units, Porsche Tiptronic, and Volvo Aisin-Warner units are also core parts of our rebuild workload.
For PDK-equipped Porsches, most faults are sensor or clutch pack related rather than requiring a full rebuild. Similarly, Volkswagen Group DSG faults across Audi, VW, SEAT and Skoda are usually addressed through clutch or mechatronic replacement rather than a complete rebuild. We diagnose first and recommend the right scope of work, not the largest one.
For Mercedes, Jaguar, Land Rover, and certain BMW dual clutch models, the fault is often the dual clutch pack or mechatronic unit rather than the full gearbox. Again, diagnosis determines the actual repair scope.
Japanese and Korean Makes Toyota, Honda, Nissan, Hyundai, Kia, Mazda, Lexus, Subaru, Suzuki, Mitsubishi, MG, Infiniti.
CVT rebuilds form a significant part of our Japanese and Korean car workload. Nissan Xtronic CVT units, particularly from high-mileage Sylphy and Almera cars including ex-taxi units, are among the most common rebuilds we complete. Toyota CVT, Honda petrol CVT, Subaru Lineartronic, Mitsubishi INVECS-III, and Hyundai and Kia CVT units are all regularly handled.
Honda Vezel and HR-V Hybrid models use an e-CVT which is a different system from a conventional belt-and-pulley CVT. If you drive a hybrid variant with transmission concerns, WhatsApp us and we will advise on what applies.
Mazda’s SKYACTIV-Drive conventional automatic is a well-engineered unit that responds particularly well to a proper rebuild when mileage-related wear develops.

Questions People Ask About Gearbox Rebuilds in Singapore
What is the difference between a gearbox rebuild and a gearbox overhaul?
In practice, the terms refer to the same process: full disassembly, replacement of all consumable internal components, and reassembly to a standard that restores original performance. Some workshops use one term, some use the other. What matters is what actually happens to your gearbox, not what it is called. At 1 Car, a rebuild means complete strip, inspect, replace all internals, reassemble with quality parts, road test, and a 2-year / 40,000km warranty.
How much does a gearbox rebuild cost in Singapore?
It depends on the make, model, and gearbox type. Japanese and Korean CVT rebuilds typically run from S$1,800 to S$3,200. European automatic gearbox rebuilds generally range from S$2,300 to S$5,500 depending on the specific unit. Performance and luxury brand gearboxes vary based on the model. WhatsApp us your car details and we give you a realistic ballpark before you come in.
How long does a gearbox rebuild take?
2 to 5 working days for most makes and models. We confirm the exact timeline after the free diagnostic scan. Parts availability for less common European or older models can occasionally extend this and we will tell you upfront if that is the case.
Is a rebuild better than a reconditioned replacement unit?
Almost always yes. A reconditioned unit from a scrapyard comes with unknown history, unknown prior damage, and typically a 1-month warranty. A rebuild of your own unit means you know exactly what went into it, your gearbox number stays the same for LTA purposes, and it comes with our 2-year / 40,000km warranty. The only scenario where a replacement unit makes more sense is if the gearbox casing or major structural components have been damaged beyond serviceable limits, which our diagnosis will identify.
What is included in the rebuild price?
All consumable internal components: clutch packs, all seals, all gaskets, transmission filter, and correct-specification transmission fluid. External components including the torque converter, valve body, control modules, oil pan, and autocooler are not included unless found to be faulty during diagnosis. You pay to fix what is worn, not a fixed package that includes parts your car does not need.
Do I definitely need a full rebuild or could it be a smaller fix?
This is exactly what the free diagnostic scan determines. A significant number of gearbox faults, particularly in Porsche PDK, Volkswagen Group DSG, Mercedes dual clutch, and Hyundai and Kia DCT equipped cars, are targeted component issues rather than full rebuild jobs. We tell you which one applies to your car after the diagnosis. If a smaller repair resolves the fault, that is what we recommend.
My car is in limp mode. Does it need a rebuild?
Not necessarily. Limp mode means the transmission control unit has detected a fault and restricted the gearbox to protect it. The fault could be a failing sensor, a solenoid issue, low fluid, or an internal wear fault that requires a rebuild. Only a proper diagnostic scan with brand-specific equipment tells you which one it is. Do not drive it further. Come in or arrange a tow for the free diagnostic check.
Is the 2-year / 40,000km warranty really the longest in Singapore?
Yes. For gearbox rebuild work, our 2-year / 40,000km warranty is the longest available in Singapore. We offer it because every gearbox we rebuild is built to last 100,000km or more under normal driving conditions and we stand behind that standard.
My car cannot drive. Can you tow it in?
Yes. WhatsApp us and we will arrange towing to our workshop at Sin Ming AutoCity. If your gearbox is symptomatic, do not push it further than necessary.
Why should I choose 1 Car over other gearbox rebuild workshops in Singapore?
2,000+ rebuilds completed. Brand-specific diagnostic tools for every major make. Singapore’s longest warranty. Transparent pricing before we start. Original and OEM-grade parts throughout.
