Find out what needs fixing
A change in how your transmission behaves does not tell you which part needs replacing. The first step is to assess the vehicle and establish what is causing the problem.
Contact us if you have noticed:
Harsh or delayed shifts: A thump when changing gear, or a delay before Drive or Reverse engages.
Slipping or flaring: Engine revs rising without the acceleration you would expect.
Shuddering or juddering: Vibration when taking off, changing gear or driving under load.
Warning lights or messages: A transmission warning, flashing gear display or restricted operation.
Fluid leaks: Signs of leakage around the transmission or its associated components.
Loss of drive or unusual noises: Changes that need assessment before further use.
Tell us when the fault occurs, whether the vehicle is hot or cold, and any warning messages or codes you have. If the vehicle loses drive, has a severe leak, shows an overheating warning or cannot be driven safely, stop in a safe place and arrange roadside assistance rather than driving it to the workshop.
Transmission diagnosis before repair
Start by telling us about the vehicle and what has changed. We can discuss the initial assessment, applicable charges and booking availability before you bring it in.
Depending on the symptoms, diagnosis may involve a road test where safe, fault-code scanning, live-data checks, fluid and leak checks, or inspection of wiring and related components. Some faults require further testing or dismantling to establish the repair scope.
We explain the findings and recommended next steps before seeking approval for repair work. The aim is to distinguish a service requirement from an electrical, hydraulic or mechanical fault, rather than recommend a replacement based on symptoms alone.
Automatic transmission servicing and repairs
The work your vehicle needs depends on its transmission type, condition and the findings of the assessment. We keep preventative maintenance, fault repairs and rebuilds separate so you can understand what is being recommended and why.
Transmission servicing and maintenance
Maintenance work can include fluid and filter replacement where applicable, leak assessment, and checks or adjustments suited to the transmission. We can also discuss transmission cooling requirements for your vehicle and how it is used.
If you are booking because the transmission is slipping, shuddering or displaying a warning, let us know before requesting a routine service. A fluid change is maintenance, not a promise to correct an existing fault.
Electrical, mechatronic and component repairs
Our transmission repair work includes valve bodies, mechatronics, solenoids, sensors, wiring and transmission control modules. Depending on the confirmed fault, work may also involve seals, torque converters or DSG dual-clutch assemblies.
The appropriate repair depends on the vehicle and the condition of the surrounding components. Replacing an individual part is an option to assess, not a guarantee that every transmission can be repaired without further work.
Transmission rebuilds
Where the findings support a rebuild, we can discuss a transmission overhaul and the work it involves. This includes dismantling and inspecting the unit to establish the condition of its internal components and the required repair scope.
A rebuild is not the starting assumption for every complaint. We explain the recommended approach, the proposed work and the applicable warranty before you decide how to proceed.
A local workshop with transmission experience
Col Voss has served Sydney’s Northern Beaches since 1998. Our independent workshop is based in Brookvale, with transmission diagnosis, servicing and repair at the centre of what we do.
You can speak with us about the symptoms, the assessment and the proposed work. For a closer look at the kinds of faults we investigate, read our guides to Mazda U0101 and TCM communication faults and DQ381 transmission diagnosis and repair.
Warranty for your repair
Warranty coverage depends on the work carried out and the terms applicable to your job. Selected transmission rebuilds are available with a warranty of up to 3 years or 60,000 km, whichever occurs first, subject to the applicable terms.
This is not a blanket warranty for every transmission service, component or repair. Ask us to explain the coverage for the proposed work and read our parts and labour warranty information.
Questions before you book
Can you quote a transmission repair over the phone?
We can discuss the symptoms and how to arrange an assessment, but symptoms alone are not enough to establish the repair scope. An inspection, testing or further investigation may be needed before we can quote the repair.
Will a transmission service fix slipping or shuddering?
Do not book a routine service on the assumption that it will fix those symptoms. Tell us what the vehicle is doing so we can discuss an assessment and determine whether maintenance or fault repair is appropriate.
Does a transmission fault mean I need a complete rebuild?
Not necessarily. The findings may support a component repair, more extensive work or a rebuild, depending on the fault and the condition of the transmission.
Can I enquire about a DSG, dual-clutch or CVT transmission?
Yes. Tell us the vehicle’s make, model, year and symptoms so we can confirm the assessment and service options available for your particular transmission.
Do I need a Furitech report before booking?
No. You can contact Col Voss directly to request a workshop assessment.
If you already have a report from Furitech, or findings from another workshop, let us know when you enquire. That information can provide context, but it does not replace inspection and testing of your vehicle.
What should I include in my enquiry?
Include your registration, make, model and year, along with a short description of the problem and when it occurs. Mention any warning messages, fault codes, previous repairs and whether the vehicle can currently be driven.
