A slipping, jerking or limp-mode gearbox is a job for a workshop that actually opens up transmissions, not only changes oil. This guide gathers eight Singapore workshops whose own websites describe gearbox or automatic transmission repair, overhaul or servicing, from dedicated specialists to general garages that also have a gearbox bay. We describe only what each business publishes about itself, attribute those claims, and leave out prices entirely, since quotes depend on the car and the diagnosis. Use the list to shortlist two or three, check which transmission types and car brands each one names, and read the how-to-choose notes below before you approve any teardown or authorise a rebuild.

1. Jackson Powertrain

Jackson Powertrain presents itself as an automatic transmission specialist, and its site has a dedicated gearbox repair page covering overhaul of automatic gearboxes, CVT units and torque converter rebuilds. The same website also lists engine overhaul, oil changes and hybrid battery replacement, which may suit owners who prefer one workshop for several drivetrain jobs. It works from an industrial building in the Loyang area on the east side of the island and publishes weekday and Saturday opening hours, with Sundays and public holidays closed. Its page says gearbox overhauls come with a time-and-distance warranty, so ask exactly what that covers before agreeing to a rebuild. Enquiries go through an email address and phone number shown on its contact details.

2. Gearbox King

Gearbox King describes itself as a gearbox specialist working inside Sin Ming AutoCity. Its homepage lists gearbox overhaul, gearbox servicing, mechatronics unit repair, torque converter repair and valve body repair, across automatic, CVT, dual-clutch and Porsche PDK transmissions. It says it handles Continental makes such as Audi, Volkswagen, Porsche, BMW and Mercedes, as well as Japanese and Korean cars. The site also mentions a free towing arrangement for gearbox jobs and a two-year or 40,000 km cover on overhauls, both stated by the workshop itself. Customers are pointed towards WhatsApp for enquiries, and weekday and Saturday hours are published, so confirm towing terms, the exact warranty wording and what each covers in writing before work begins.

3. Ellipse Auto Transmission

Ellipse Auto Transmission is another specialist in the Sin Ming AutoCity cluster, and its website is organised around automatic transmissions rather than general servicing. Services listed include rebuilding, overhauling or repairing automatic gearboxes, torque converter rebuilding, transmission parts supply and routine automatic transmission maintenance. It also says it can supply brand new or reconditioned transmissions for a wide range of models, and names the parts brands it works with, including ZF South East Asia among them. The company describes diagnostic equipment for both mechanical and electronic faults. It publishes two phone lines, an email address and a contact page, along with weekday and Saturday hours, so you can request a diagnosis before committing.

4. 1 Car Service Workshop

1 Car Service Workshop is a Sin Ming AutoCity garage whose homepage and service pages put gearbox work front and centre alongside engine and aircon repair. Its gearbox overhaul page lists dual-shift, automatic, CVT, dual-clutch, Porsche PDK, automated manual and conventional manual gearboxes, with further pages aimed at BMW, Audi and Volkswagen owners and other Continental models. The workshop states that overhauls carry a two-year or 40,000 km warranty and describes symptoms such as jerking, slipping and limp mode as typical reasons to call. It publishes weekday and Saturday hours, a phone number, an email address and a contact page, so a diagnosis request is easy to start. Note that this workshop also appears on LocalRank's car servicing guide.

5. MCM Garage

MCM Garage runs a workshop in the Kaki Bukit industrial area and describes itself as an automatic engine and transmission specialist. Its site lists automatic transmission and engine servicing, gearbox repair and overhaul, and diagnostic troubleshooting for automatic transmission faults across makes and models. Beyond drivetrain work, it also advertises general servicing, air conditioning repair and accident repair with insurance claims support, so it can double as an all-round garage after the gearbox is sorted. The business says warranty and a free car diagnostic are available, subject to its own terms. Opening hours run Monday to Saturday, and it lists payment methods including PayNow and cards. Ask what the diagnostic covers before leaving the car.

6. Doctor Gearbox

Doctor Gearbox positions itself as a dedicated gearbox specialist rather than a general repair shop, working from a business centre unit off Kaki Bukit Road. Its website sets out a ladder of services: diagnosis, repair, fluid servicing, full or partial rebuilds, help sourcing a replacement transmission for an ageing vehicle, and preventive management. It says it covers Continental, Japanese and Korean gearboxes for both private and commercial vehicles. A notable detail is the spread of published hours, which include longer weekday evenings and Sunday opening, something not every workshop offers. Booking is available by phone, email and WhatsApp as listed on its contact page. As with any rebuild, ask for the findings before approving the work.

7. Battery Lab

Battery Lab is best known on its own site for hybrid battery repair, but it also lists gearbox repair and overhaul as a core service and publishes a dedicated gearbox page. That page describes automatic, CVT, dual-clutch and hybrid eCVT transmissions being diagnosed, repaired and rebuilt in its own workshop, including mechatronic repairs and clutch pack replacement for several dual-clutch designs. It operates from an industrial centre in the Woodlands area and states a two-year or 40,000 km warranty on gearbox work. Aircon repair is listed too. Owners of hybrid vehicles may find a workshop that handles both the battery and the gearbox convenient. Contact details and a form are on its contact page.

8. Revol Carz Garage

Revol Carz is mainly known for coating and paintwork, but its garage arm lists European-car servicing, and a May 2026 article on its own site sets out its gearbox approach. The article describes diagnostic scanning, fluid analysis and changes, repairs, rebuilds and replacements, hydraulic pressure testing and mechatronic unit diagnosis, with specific mention of dual-clutch DSG units, CVT gearboxes and conventional torque-converter automatics. It names two Singapore sites, in Ang Mo Kio and Toh Guan, and offers an online inquiry form and WhatsApp contact. The garage focuses on Mercedes, BMW, Audi and Volkswagen, so owners of other brands should confirm coverage before booking. The business also appears on LocalRank's car workshops guide.

How to choose

Match the transmission type first. Automatic, CVT, dual-clutch, Porsche PDK and manual gearboxes are different jobs, and each workshop here names the types and car brands it handles. Ask whether it has opened your exact gearbox code before, rather than relying on a general claim about transmissions.
Ask for a diagnosis in writing before any teardown. A clear findings note should say what failed, whether a repair, a rebuild or a replacement unit is proposed, and what remains uncertain. Compare that note across two workshops instead of comparing only the final amount you are quoted.
Read the warranty wording yourself. Several workshops on this list publish a time-and-distance warranty on overhauls, but terms differ in what is covered, whether labour is included, and what voids it. Ask for the conditions in writing and whether repairs elsewhere would affect the cover.
Check practical logistics. Some workshops mention towing, WhatsApp updates or evening opening hours on their own sites, while others list only weekday daytime slots. Confirm turnaround time, where the car will be kept, and whether a loan vehicle or pickup is offered for your case.
Be clear on parts and sourcing. Ask whether the work uses new, reconditioned or used parts, which brands, and whether the old components are returned. A transparent workshop should explain why a rebuild is proposed instead of a fluid service, especially when symptoms are mild or intermittent.
