How your gearbox works

The part that turns engine power into motion

An engine only works well within a certain range of speeds. The gearbox, also called the transmission, uses different gear ratios so your car can pull away from a standstill and then cruise at highway speed without the engine straining. A manual uses a clutch pedal and a gear lever you move yourself. An automatic changes gear for you, using fluid pressure and a control module (a small computer that decides when to shift).

Many newer cars use a CVT (continuously variable transmission), which swaps fixed gears for a steel belt running between two pulleys. Others use a dual-clutch gearbox, which works like two manuals sharing one case. 4WDs and many utes add a transfer case to send drive to the front wheels. Each type wears in its own way, so the right repair depends on finding exactly which part is at fault.

Fluid does a lot of the work. It lubricates and cools the gears, and in an automatic it carries the pressure behind every shift. Heat breaks it down. A summer afternoon crawling along Anzac Avenue through Kallangur works an automatic far harder than the same time at a steady speed on the Bruce Highway.

What we check

An inspection that covers the whole driveline

A gearbox symptom can come from the gearbox itself or from the parts around it. We check both, so you are not paying for major gearbox work when the real fault is a worn mount or a tired clutch.

  • Fluid level and condition

    We check the level, colour and smell. Dark, burnt or gritty fluid tells us a lot about what is happening inside.

  • Fault codes and live data

    On automatics, CVTs and dual-clutch gearboxes, we read the transmission control module for stored codes, fluid temperature and shift data.

  • Road test on local roads

    We drive your car through the conditions you describe, such as a cold start or a hill, to feel the shifts and hear any noise.

  • Clutch and its hydraulics

    On manuals, we check how the clutch engages, how the pedal feels and the hydraulic cylinders that operate it.

  • Leaks, seals and cooler lines

    We look for weeping seals, a leaking sump pan or damaged cooler lines, because a slow leak can starve a gearbox of fluid.

  • Mounts and shift linkages

    Worn gearbox mounts and stretched shift cables can cause clunks and vague changes that feel like an internal fault.

  • Driveshafts, CV joints and diffs

    Clicks and whines can come from the parts that carry drive to the wheels, including the differential, which lets each wheel turn at its own speed through corners.

  • Transfer case on 4WDs

    On 4WDs and all-wheel-drive utes, we check the transfer case, its fluid and how cleanly four-wheel drive engages.

Warning signs

When your gearbox is asking for attention

Gearbox faults usually start small, and catching them early often means a simpler repair. If you notice any of these, such as when pulling away uphill in Albany Creek, book a check.

  1. Slipping gears

    The revs rise but the car does not speed up to match.

  2. Delayed or harsh shifts

    A pause before Drive engages, or a thump as it changes gear.

  3. Whining, humming or grinding

    A noise that changes as you change gear or road speed.

  4. A clutch that slips or grabs

    Revs flare under load, or the pedal bites very high or feels spongy.

  5. Red or brown drips

    Automatic fluid is often red when new, so a drip under the middle of the car is worth checking.

  6. Warning light or limp mode

    A gearbox light shows, or the car holds one gear to protect itself.

How it works

From first symptom to a smooth shift

  1. 1

    Tell us what you feel

    Book in and describe the symptom: which gear, hot or cold, uphill or flat. A detail like 'only on the drive home from Brendale' helps us repeat it.

  2. 2

    We diagnose the cause

    We road test, check the fluid, read the codes and inspect the driveline. Then we send you a video of what we found.

  3. 3

    You approve the repair

    We explain the fault and your options in plain English, from fixing an outside part through to repairing or replacing the gearbox, with the price. Nothing goes ahead without your OK.

  4. 4

    Repair and final road test

    We do the agreed work, road test the car again and show you the old parts when you collect it.

Why DreamWorks

Straight answers on a costly repair

Gearbox work can be expensive, so a wrong guess costs real money. Here is how we keep it honest for drivers across Strathpine, Petrie and Bray Park.

  • Diagnosis before parts

    We confirm the cause before recommending any work, so you are not paying for a gearbox when the fault is a sensor, a seal or a mount.

  • Video you can watch

    You see the fluid, the leak or the worn part on your phone before you decide what to do.

  • 20+ years across all makes

    Small cars, family SUVs, work utes, 4WDs, European cars and hybrids, with diagnostic equipment suited to modern models.

  • Local, licensed and insured

    Our workshop on Leanne Crescent in Lawnton is fully licensed and insured, with Saturday appointments available on request.

From our Google reviews

“Had my clutch and master cylinder replaced, 100000km service and got a road worthy. The work was done within 2 days and the car has never driven better. The work was affordable and there was no messing around. I got a video update on what was happening and what needed to be replaced. ... told me exactly what I needed for a road worthy and there where no unforeseen costs.”

Konrad

“It's obvious that ... approach to mechanical work is really thorough! He's very honest and you can't help but leave his workshop feeling confident that your car has had more than 'just a service', even if that's the only work you've had him do. Recently with my car, he picked up a lot of minor details that many of my previous other mechanics have just skimmed over in the past. He fixed them all up for a really fair price, and without any hassles at all. Now my little old car drives way way better than it has in years!”

Gearbox and transmission questions

Your questions, answered

Is it safe to keep driving with a slipping gearbox?

It's best not to. A slipping gearbox can lose drive without warning, which is risky when you are merging onto the Bruce Highway or crossing a busy intersection. Driving on it can also turn a smaller fault into internal damage. Book a check as soon as you can.

Does a shifting problem mean I need a new gearbox?

Not always. Many shifting problems come from low or worn fluid, a leaking seal, a faulty sensor or solenoid (an electrically operated valve that controls shifts), or a worn mount. We find the cause first. If the gearbox does need major work, we explain the options and the cost before you decide.

Do you repair gearboxes on diesel utes and 4WDs?

Yes, we look at gearbox and transmission problems on diesel utes and 4WDs, both manual and automatic. Diesels make strong pulling power at low revs, so towing a boat or trailer up the Bruce Highway or loading a ute for work puts extra heat and strain through the gearbox and clutch. If you notice slipping, harsh shifts or a clutch that feels different, we can check it and explain whether it needs a fluid service, an adjustment or a repair.

Should my automatic transmission fluid be changed?

It depends on the car. Some manufacturers set a change interval, while others call the fluid 'lifetime' under normal use. Heat and stop-start traffic, both common around Moreton Bay, can shorten its life. We check your manufacturer's schedule and the fluid's condition, then tell you whether a change is worth doing. The correct fluid type matters, because the wrong one can cause shift problems.

My car is still under the manufacturer's warranty. What should I do?

A gearbox fault may be covered by the manufacturer's warranty, so check with them or the dealer first. Australian Consumer Law also gives you consumer guarantees on new cars. If you'd like an independent look at what's wrong, we can diagnose it and explain what we find.

Do you work on CVT and dual-clutch gearboxes?

Yes. We work on all makes and models, including manuals, conventional automatics, CVTs, dual-clutch gearboxes and 4WD transfer cases. We use diagnostic equipment suited to European and hybrid cars. Many hybrids use their own style of transmission, and we check them with that in mind.

How much will my gearbox repair cost?

It depends on the fault, which is why we diagnose first. Replacing a leaking seal and rebuilding a gearbox are very different jobs. Once we know the cause, we give you the price before any work starts, so you know where you stand.
