Singapore’s Top Rated Gearbox Overhaul Workshop with 2-Year Warranty
Japanese and Asian Car Gearbox Specialists · Sin Ming AutoCity · Multi-Brand Diagnostic Tools
Your Japanese Car Has Been Reliable for Years. Until Now.
That’s the thing about Japanese and Korean cars. They earn a reputation for going and going without complaint. So when the gearbox starts playing up, it catches owners completely off guard.
Slipping on the expressway. Jerking at the traffic light. That horrible hesitation when you pull away. You know something is wrong but you’re not sure how serious it is or how much it’s going to cost.
Here’s what fixing thousands of gearboxes across Toyota, Honda, Nissan, Hyundai, Kia, Mazda, Lexus, Subaru, Suzuki, Mitsubishi, MG and Infiniti has taught us. High mileage catches up with every gearbox eventually. The good news is that catching it at the right time makes the fix significantly cheaper than leaving it.
Free diagnosis. Transparent pricing. Honest advice on what your car actually needs.
Japanese Cars and Gearboxes: What Singapore Owners Need to Know
Japanese and Korean car brands use a wider variety of transmission technologies than most owners realise. The repair approach, cost, and urgency depend entirely on which system your specific car is running. Here is a practical breakdown of what’s common on Singapore roads and what typically goes wrong.
CVT: The Most Common Transmission Across Japanese and Korean Brands
Continuously Variable Transmission is fitted across the majority of Japanese and Korean passenger cars sold in Singapore over the past 15 years. Toyota Corolla, Honda Civic, Nissan Sylphy, Subaru Forester, Hyundai Elantra, Kia Picanto, Mitsubishi Attrage, Suzuki models and many Infiniti variants all run CVT systems in their petrol versions.
CVTs are smooth and fuel efficient when working properly. When they start to go, the symptoms are hard to ignore: slipping under acceleration, shuddering at low speed, whining noises at highway speed, delayed engagement, or overheating warnings on the dashboard.
A CVT overhaul means stripping the unit completely and replacing all the consumable internal components: the drive belt or chain, pulleys, solenoid valves, clutch assembly, all seals, all gaskets, the transmission filter, and the correct manufacturer-specified CVT fluid. Rebuilt to last 100,000km or more under normal driving conditions. Every CVT overhaul comes with our 2-year / 40,000km warranty, the longest available in Singapore.
Most CVT overhauls for Japanese and Korean models run from S$1,800 to S$3,200 depending on the brand and specific unit. A fraction of what the dealer charges for a replacement unit.
One important distinction for Honda owners. The petrol Vezel and petrol HR-V use a conventional belt-and-pulley CVT covered by our overhaul service. The Hybrid versions of both models use an e-CVT, which is a fundamentally different electric-motor-based system. If you have a Honda Hybrid with transmission concerns, WhatsApp us and we will advise honestly on what applies to your car.
Nissan Xtronic CVT: A Special Mention
Nissan’s Xtronic CVT fitted to the Sylphy, Almera, Qashqai, X-Trail, Teana, Latio and Note is one of the most frequently repaired transmission units in Singapore. High mileage Sylphy and Almera units in particular, including ex-taxi cars, are extremely well-known to our technicians. We see these every week and know exactly what fails and why.
If you drive a Nissan with a slipping or shuddering gearbox, especially an ex-taxi or high mileage unit, come in for a free check. Most of these are very fixable at a fraction of what people expect.
Conventional Automatic Gearbox
Mazda is the standout example of a Japanese brand that has largely stuck with conventional torque converter automatic gearboxes across its range rather than switching to CVT. The SKYACTIV-Drive 6-speed automatic is a well-regarded unit that responds well to a proper overhaul when internal wear develops at higher mileage.
Lexus non-hybrid models, certain Honda models, older Toyota platforms, and some Hyundai and Kia variants also use conventional automatic gearboxes. When these need attention the approach is a full strip, inspection, replacement of all consumable internals, and a rebuild to the same standard as any other overhaul we carry out.
Toyota and Lexus Hybrid eCVT
Toyota and Lexus hybrid models use a power-split device known as an eCVT. This is not a belt-and-pulley CVT in the conventional sense. It uses electric motors and a planetary gear set to blend power from the petrol engine and the hybrid battery. Common across the Prius, Corolla Hybrid, RAV4 Hybrid, and most Lexus hybrid models.
Hybrid transmission issues require a different diagnostic and repair approach from conventional CVT work. WhatsApp us with your hybrid model and symptoms and we will advise on what is involved.
Hyundai and Kia Dual Clutch (DCT)
Higher output Hyundai and Kia models, including certain Tucson, Sonata, Sportage and K5 variants, use a dual clutch transmission rather than a CVT. Similar to the VW Group DSG in concept. When these develop faults the issue is usually the clutch pack or the mechatronic control unit rather than the full gearbox. We diagnose first before recommending a repair scope.
MG
MG, now a Chinese-owned brand, uses a mix of CVT and DCT transmissions depending on the model. The newer MG models increasingly use DCT setups. We assess each car individually after a diagnostic scan to confirm the exact unit and what it needs.

Symptoms to Watch For Across All Japanese and Korean Models
Slipping Under Acceleration Engine revs build but the car doesn’t accelerate properly. Classic CVT belt or pulley wear. The earlier you address this the less the repair costs.
Shuddering or Jerking at Low Speed That juddering sensation when pulling away from a standstill or crawling in traffic. Points to worn solenoids, degraded fluid, or clutch pack wear. Very common on high-mileage Nissan CVT units.
Delayed Response When Selecting Drive or Reverse A noticeable pause before the car moves. An early warning sign on both CVT and conventional automatic gearboxes. Worth checking before it develops into something larger.
Whining or Droning Noise at Highway Speed Specific to CVT-equipped cars. The characteristic noise of a CVT under strain, usually from belt or pulley wear. Owners often assume it’s a tyre noise. It usually isn’t.
Overheating Warning Transmission temperature light on the dashboard. Overheating accelerates internal wear dramatically. Stop driving and get it checked immediately.
Limp Mode or Loss of Drive The transmission control unit has detected a fault serious enough to restrict normal operation. Needs a proper diagnostic scan, not a reset and a hope.
Fuel Consumption Increasing Without Explanation A slipping or inefficient CVT forces the engine to work harder. Unexplained fuel consumption increases in a Japanese car with a CVT are sometimes the first sign of a developing gearbox fault.
💡 Real talk: Most Japanese and Korean car owners are pleasantly surprised by the repair cost compared to what they feared. A CVT overhaul on a Nissan Sylphy, Toyota Corolla, or Honda Civic is a manageable job when caught at the right time. The expensive scenario is waiting until the unit fails completely. Drive in for a free check and find out where you actually stand.
What a Full Gearbox Overhaul Includes
Every overhaul covers all the consumable parts inside the gearbox. The components that wear out over time and need replacing regardless of which specific unit your Japanese or Korean car is fitted with.
✓ Clutch packs or CVT clutch assembly
✓ CVT drive belt or chain (where applicable)
✓ CVT pulleys reconditioned or replaced (where applicable)
✓ Gearbox internal seals
✓ Gearbox gaskets
✓ Transmission filter
✓ Gearbox fluid for your exact model
External components including the engine, flywheel, control modules, valve body, oil pan, torque converter, and autocooler are not included in the standard overhaul because they do not need replacing if they are not faulty. We inspect them during diagnosis. If something external is contributing to the gearbox problem we tell you upfront and include it in the quote. You pay to fix what’s broken, not everything on a checklist.
Brand-Specific Diagnostic Scan Every job starts with a scan using diagnostic tools matched to your specific brand. This gives us accurate fault data before we open anything up. No guessing about what’s causing the symptoms.
Full Disassembly and Inspection The gearbox comes fully apart. Every component is inspected. We find what is actually failing and build the repair scope around that.
Rebuild with Original or OEM-Grade Parts Top-grade components throughout. The quality of what goes back inside determines how long the overhaul lasts. We do not cut corners here regardless of whether your car cost S$30,000 or S$300,000.
Post-Overhaul Road Test and Final Verification Every car gets a proper road test before you collect it. If it isn’t right, it doesn’t leave the workshop.
The Process:
Step 1: Free Diagnosis. Brand-specific scan and physical inspection. No charge. No obligation.
Step 2: Transparent Quote. Itemised breakdown of the exact work required and what it costs. You approve before we start.
Step 3: CVT Overhaul or Targeted Repair. Most jobs completed within 2 to 4 days.
Step 4: Collect with Warranty. Road-tested. 2-Year / 40,000km warranty issued on full overhauls.

Questions about Japanese and Korean Gearbox Overhaul
My Japanese car has been reliable for years. Why is the gearbox suddenly failing?
CVT gearboxes have a natural lifespan. Most run well until 80,000 to 120,000km before wear accumulates to a point where symptoms start showing. Japanese cars being reliable does not make their transmissions immune to mileage. The good news is catching it at the symptom stage rather than the failure stage makes a significant difference to what the repair costs.
How much does a CVT overhaul cost for a Japanese car?
Most Japanese and Korean models run from S$1,800 to S$3,200 depending on the specific brand and CVT unit. We confirm the exact figure after the free diagnostic scan. WhatsApp us your model and year for a ballpark straight away.
What does the overhaul include?
All consumable internal parts: clutch assembly, drive belt or chain, pulleys where applicable, all seals, all gaskets, transmission filter, and correct-spec CVT fluid. External components are only replaced if found to be faulty during diagnosis. You pay to fix what’s broken.
I drive a Honda Vezel or HR-V Hybrid. Is the CVT overhaul applicable?
No, and this is important to get right. The Honda Vezel and HR-V Hybrid use an e-CVT, which works on electric motor and planetary gear principles rather than a conventional belt-and-pulley system. Our CVT overhaul covers the petrol Vezel and petrol HR-V only. If you have a Hybrid model with transmission concerns, WhatsApp us and we will advise honestly on what applies.
My Nissan Sylphy is a high mileage ex-taxi. Is an overhaul still viable?
Yes, and we do this regularly. High mileage Sylphy and Almera units, including ex-taxi cars, are among the most common CVT jobs we handle. Nissan’s Xtronic CVT has well-documented failure modes at higher mileage that we know how to address. After the free diagnosis we will tell you straight whether an overhaul or a replacement unit makes more sense for your specific car.
My Toyota or Lexus is a hybrid. Does the overhaul apply?
Toyota and Lexus hybrid models use an eCVT that operates differently from a conventional CVT. WhatsApp us your specific model, year and what symptoms you are experiencing. We will advise on what is involved before you come in.
Is the warranty really 2 years or 40,000km?
Yes, on every full gearbox overhaul. Longest available in Singapore. Most workshops offer 1 to 6 months on gearbox work. We offer 2 years or 40,000km, whichever comes first, because we stand behind how we rebuild.
How long does a Japanese car CVT overhaul take?
2 to 4 working days for most models. We confirm after the free diagnosis and keep you updated throughout so you can plan around the downtime.
My car is undriveable. Can you arrange towing?
Yes. WhatsApp us and we will arrange towing to our workshop at Sin Ming AutoCity. Do not drive a car with a slipping or shuddering CVT further than necessary. The additional wear adds to the repair cost.
Another workshop told me I need a full replacement. Is that right?
Come in for a free diagnostic scan before committing to anything. In our experience, replacement recommendations for Japanese CVT units are frequently made without a thorough internal inspection. A full overhaul achieves the same result at a fraction of the cost and comes with a proper warranty. We will tell you honestly after the scan what your car actually needs.
