Power to the ground, every gear
From a slipping clutch to a whining diff or a crunching AMT, driveline trouble only gets more expensive the longer you run it. We repair, rebuild and recalibrate every part of the driveline so power gets to the ground cleanly.
The driveline is everything between the back of the engine and the road — the clutch, the gearbox, the tailshaft and the differentials — and it lives a hard life under enormous load. A heavy combination launching a fully-laden trailer up a grade puts colossal stress through every one of those components, and when one starts to fail, the symptoms are hard to ignore: a clutch that slips or shudders, a gearbox that crunches, jumps out of gear or whines, a diff that howls, or a vibration through the floor that gets worse with speed. Left alone, these faults rarely fix themselves — they get more expensive.
We work across the full range of heavy-vehicle drivelines, from traditional crash and constant-mesh manuals to modern automated manual transmissions (AMTs) and full automatics. Our technicians understand the mechanical side and the electronic side — because on a modern AMT, a shifting complaint is as likely to be a clutch actuator, a sensor or a software calibration as it is worn gears. We diagnose accurately, repair or rebuild what needs it, and recalibrate the system so the truck shifts the way the manufacturer intended.
Driveline work we carry out
- Clutch replacement, including heavy-duty and ceramic upgrades
- Manual, AMT and automatic transmission repair and rebuild
- AMT clutch actuator, sensor and calibration faults
- Differential repair, rebuild and ratio changes
- Tailshaft, universal joint and centre-bearing replacement
- Driveline vibration diagnosis and balancing
Catch it early, save the big bill
Driveline components give plenty of warning before they let go — a noise, a vibration, a smell, a change in how the truck shifts or pulls. The operators who save the most money are the ones who book it in the moment something feels off, rather than running it until the gearbox locks up on the highway and takes the tailshaft and a recovery bill with it. A small clutch or bearing job caught early is a tiny fraction of the cost of a catastrophic driveline failure mid-run, plus the towing and downtime that come with it.
Rebuilt right, set up right
When we rebuild a gearbox or a diff, it is done properly — correct end-float, correct backlash, correct preload, quality bearings and seals, and the right oil to the right level. We set drivelines up to specification and road-test under load before handover, so the truck goes back to work shifting cleanly, running quietly and pulling without drama. And because we keep detailed records, anything we touch is documented for your service history and your fleet program.
Heard a new noise from the driveline? Don't wait for it to get worse. Book a diagnosis and we'll tell you exactly what's going on.
Transmission & Driveline questions
Yes. We diagnose and repair AMT mechanical and electronic faults — including clutch actuators, sensors and calibration — across all the major brands, not just traditional manual boxes.
We can. Whether you're re-gearing for a change in work, fuel economy or top-end speed, we supply and fit the right ratio and set the diff up correctly.
Yes. Vibrations usually come from worn universal joints, centre bearings or an out-of-balance tailshaft. We diagnose the source, replace what's worn and balance the driveline so it runs smoothly.
