Rebuild Transmission, Gearboxes, Diffs and Power Steering.

25/08/2026

Lift kit. 35s. A tune that woke it right up. Looks the part.

Here is the thing though. Bigger tyres, more weight and more power all put extra strain on the parts you cannot see.

Your transmission, transfer case and diffs were built for a factory 4WD, not the one you have created.

If you have built yours up, make sure the driveline can keep up. We will check it is all handling the load.

Buying a used 4WD? The paint job tells you nothing.

Plenty of tidy-looking rigs are hiding a tired transmission or a diff on its way out.

By the time you find out, it is your problem, not the seller’s.

Before you hand over the cash, get the driveline looked over.

A quick check now is a lot cheaper than a rebuild you did not budget for. Come and see us in Cannington.

Towing puts a transmission under stress most drivers never think about.

The heat, the load, the constant shifting - it adds up fast. Automatic transmissions in tow vehicles need more attention than most people give them. Fluid degrades quicker. Components wear faster. The margin for "she'll be right" gets a lot thinner.

S&G Gearbox works on everything from everyday autos to heavy-duty tow vehicles. If you're heading into the season with a loaded trailer behind you, it's worth knowing your transmission is actually up for it.

Manual gearboxes don't get as much attention as automatics - but they're not maintenance-free.

Synchromesh wear, worn shift forks, gear oil that hasn't been changed in years. Most manual transmission problems develop slowly, which is exactly why they get ignored until something finally gives way.

S&G Gearbox rebuilds manuals as well as autos. If yours is getting harder to shift, jumping out of gear, or just doesn't feel the way it used to - it's worth a look.

Your diff doesn’t get much attention, until it demands it. ⚙️

Differentials wear quietly in the background, especially if you tow, carry loads, or head off-road. A hum or whine at highway speed is usually the first sign something’s on its way out and leaving it only makes the repair bill bigger.

S&G rebuilds and repairs diffs for regular to heavy-duty 4WDs.

Your transmission fluid does more than you think. 🛢️

It cools, lubricates and creates the hydraulic pressure your gearbox needs to shift properly. Over time it breaks down, and that’s when you start noticing sluggish shifts, slipping, or an unexplained shudder.

A transmission service at the right intervals is one of the cheapest ways to protect a component that costs thousands to replace.

Don’t guess - get it checked.

Not all gearbox work is created equal. 🔧

There's a big difference between pulling a transmission, swapping some parts, and putting it back together — and actually rebuilding it properly with quality components and post-job testing to confirm it's right.

At S&G we recondition automatic transmissions, manual gearboxes, transfer cases and differentials to a standard that holds up — whether you're doing school runs or serious off-road work. Backed by our written warranty.

If you've had work done elsewhere and something still isn't right, we're worth a call. 📞 (08) 9356 9988 | 📍 18 Marriott Street, Cannington

That noise your 4WD started making last trip? It didn't fix itself.

A clunk under load, a hesitation when you shift, a whine that wasn't there six months ago — these are your drivetrain talking. The longer you leave it, the more expensive the conversation gets.

S&G Gearbox has been diagnosing and rebuilding transmissions, transfer cases and differentials since 1977.

We've heard every noise, seen every failure, and we know the difference between "keep an eye on it" and "fix this before it ruins your next trip."

Book a check before it becomes a recovery story.

Did you know your transmission fluid should be checked and serviced every 12 months or ~30,000 km — whichever comes first?

Keeping fluid clean and correctly filtered prevents heat, wear and costly breakdowns.

If your steering feels heavy, gears grind, or you hear odd noises, it might be time for a proper check — we don’t just refill fluid, we fully service it including gasket & filter changes.
