If you operate a heavy vehicle, you already know that a reliable transmission is the heart of your rig’s performance across Australia’s demanding roads. Whether you are hauling freight interstate or managing a local fleet, when gearbox issues arise, you need specialists who understand the complex mechanics of heavy-duty drivetrains — and that’s where Nova Automatics comes in.
Located in Holden Hill, we are Adelaide’s trusted name in heavy transmission services, with decades of experience servicing and rebuilding both automatic and manual gearboxes for commercial and heavy-duty industrial vehicles.
Modern heavy automatic transmissions, such as those from Allison or ZF, are incredibly complex systems that rely on a perfect balance of hydraulics and electronics. When your automatic starts “hunting” for gears or shifting harshly, it often points to a solenoid issue or a fluid pressure problem. Our workshop is equipped with the latest software to communicate with your transmission’s Control Module (TCM), allowing us to recalibrate shift points and clear fault codes that standard scanners might miss.
To prevent expensive rebuilds, we emphasize the importance of specialized automatic transmission flushing and cooling. Heavy-duty automatics generate immense heat, especially when towing or operating in Australian summer conditions. We provide thorough fluid analysis and high-flow cooling upgrades to protect your torque converter and planetary gear sets from thermal breakdown. By maintaining the integrity of the hydraulic system, we help you extend the lifespan of your automatic transmission and avoid the high costs of a total replacement.
Manual transmissions in heavy vehicles are built for durability, but the constant stress of heavy hauling can lead to significant internal wear. Our technicians specialize in diagnosing synchronizer issues, bearing failures, and gear damage that can make shifting difficult or noisy. We don’t just swap parts; we perform teardowns to identify the root cause of the failure, ensuring that once your manual gearbox is back in the truck, it shifts with the precision and reliability required for long-distance transport.
Beyond internal gear sets, we provide comprehensive servicing for heavy-duty clutch systems and flywheels. A slipping clutch or a sticking pedal can lead to catastrophic failure if not addressed early. We offer professional machining and replacement services using high-quality components designed to withstand the high-torque demands of industrial engines. Whether you’re driving a 9-speed or an 18-speed Roadranger, we have the expertise to keep your manual drivetrain operating at peak efficiency.
There’s nothing worse than an unreliable vehicle, and the longer you leave it the worse it will get, so give Nova Automatics a call today on 08 8266 0499 and see how they can help you!
